Problem with: wildcard search in Endeca with Russian language, or adding custom stemming dictionary

Hi endeca-gurus. I need your assist in typeahead functionality to implement it with endeca (also we should able to search within * from search input-field). So, per documentation, OLT doesn't support wild card search, but latin-1 does it. So, I tried to switch to Latin-1, but it doesn’t work…maybe I performed some mistakes :
1.created file stemming file named ru_word _ forms _collection.xml and added it to the MDEX..\conf\stemming\custom directory:
<?xml version="1.0"?>
<!DOCTYPE WORD_FORMS_COLLECTION SYSTEM "word_forms_collection.dtd">
<WORD_FORMS_COLLECTION>
<WORD_FORMS>
    <WORD_FORM>ноу</WORD_FORM>
    <WORD_FORM>ноут</WORD_FORM>
    <WORD_FORM>ноутб</WORD_FORM>
    <WORD_FORM>ноутбу</WORD_FORM>
    <WORD_FORM>ноутбук</WORD_FORM>
</WORD_FORMS>
<WORD_FORMS>
    <WORD_FORM>sm</WORD_FORM>
    <WORD_FORM>sma</WORD_FORM>
    <WORD_FORM>smar</WORD_FORM>
    <WORD_FORM>smart</WORD_FORM>
</WORD_FORMS>
</WORD_FORMS_COLLECTION>
2. set USE _STATIC _WORDFORMS="TRUE" in <appname>.stemming.xml;
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<!DOCTYPE STEMMING SYSTEM "stemming.dtd">
<STEMMING>
<STEM_RU ENABLE="TRUE" USE_STATIC_WORDFORMS="TRUE"/>
</STEMMING>
3. run baseline_update script
4. try to search with params in endeca_jspref:
N=0&Ntk=All&Ntt=ноут*&Nty=1&D=ноут*&Ntx=mode+matchall&Dx=mode+matchall
And search result is zero.. ((
What the encoding should be for the edited files? any other suggestions for doing it?
and, common question : willl endeca support wildcard search for russian in close future??

Did you enable the dimension for wildcard search? In dev studio, in the dimension pane there is a button called configure search, click it and check the wildcard search checkbox in the dialog. I think you may have the stemming entry right but as OLT is fairly new I have not had a chance to test changing the default analyzer as yet. If my suggestion does not work or you have already applied the wildcard flag then I will dig a little deeper.

Wildcard search + thesaurus on xquery

Hi All,
I just realized that thesaurus matching is not supported with wildcard search.
Here is current codes.
<Searches>
if (fn:exists(http:get-query-parameter("Ntt"))) then
for $paramNtt in http:get-query-parameter("Ntt")
return <Search Mode="AllPartial" Key="i_products_st">{concat("*",concat($paramNtt,"*"))}</Search>
else ()
</Searches>
So, now i am thinking that I can change to somthing like following eql
<EqlExpression>
collection()/record[ endeca:matches(.,"i_products_st",$paramNtt,"AllPartial") or endeca:matches(.,"i_products_st",concat("*",concat($paramNtt,"*")),"AllPartial") ]
</EqlExpression>
though I didn't test it out yet. I guess there might be some other solution.
So, I would like to ask if any better way can solve this issue.
Thanks,

Are you trying to retrieve the union of (a) records that match the user's search term as literally entered, perhaps expanded by thesaurus and (b) records that match the user's search term as a substring via wildcard?
If so, then EQL can express that logic. For example, suppose that:
* the thesaurus contains an entry "truck" <-- --> "lorry"
* the user enters "truck" in the search box
EQL: collection()/record[ endeca:matches(.,"i_products_st","truck","AllPartial") or endeca:matches(.,"i_products_st","\*truck\*","AllPartial") ]
This search filter expression would match records containing: { truck, lorry, trucker, trucking, struck, ... }
This kind of infix wildcard expression has very broad recall. In this case you would probably also want to assert a relevance ranking strategy based on matching the user's original entry "truck", using Nrr.
Also worth thinking about search inputs that are multiple words like "truck driver" - would you want to implicitly wildcard every token separately e.g. \*truck\* \*driver\*
Finally, definitely worth thinking about search inputs that give pathological queries when implicitly wildcarded, like very short tokens e.g. a ==> \*a\*

Oracle BI Publisher - Passing multiple wildcard search to a bind variable

Hi,
Please help me in resolving the below mentioned issue:
I have developed a report in oracle BI Publisher with a SQL query.
While scheduling the report to run I used to pass mutilple parameters like CGAMSVC08,RLCSVC51
If the pass the parameter with wildcard search like C% it works.
When I pass two or more parameter values with wildcard search like C%,R% its not working.
Could you please let me know how should I give the bind variable in the SQL query. Currently I'm paramater like the one shown below for passing multiple paramaters:
Where (',' || :PRMRETRID || ',' like '%,'||RL.RETROFIT_ID|| ',%')

HI Tyler.
Well, here's the latest.
I found this little gem in the BIEE 10.1.3.3.3 Release Notes Documentation...
This issue applies to Versions 10.1.3.3, 10.1.3.3.1, 10.1.3.3.2, and 10.1.3.3.3.
Reports that use the BI Publisher data template as the data model may fail with the
following error: "Data not defined."
This error will occur if you defined a parameter in your data template but you do not
pass a value to it via the user interface. If you do not specify this parameter in the "Parameters" section of the report definition that you created using the BI Publisher Edit Report interface, then you will receive the error.
To work around this issue, either define the parameter in the Edit Report interface or remove the parameter from the data template.
That bit is now working.
Having set this up and using your guide it works if my SOAP parameters declaration passes a single value like this...
<parameterNameValues>
<item>
<name>P_INVOICE_ID</name>
<multiValuesAllowed>true</multiValuesAllowed>
<values>
<item>16641</item>
</values>
</item>
</parameterNameValues>
But if I try and pass two or more like this...
<parameterNameValues>
<item>
<name>P_INVOICE_ID</name>
<multiValuesAllowed>true</multiValuesAllowed>
<values>
<item>16641,18421</item>
</values>
</item>
</parameterNameValues>
BIP states "java.sql.SQLException: ORA-01722: invalid number"
My SQL where clause is..
<sqlStatement name="Q1">
<![CDATA[select * from vw_invoice_summary
where invoice_summary_id IN (:P_INVOICE_ID)]]>
</sqlStatement>
And the BIP error records the parameter value as P_INVOICE_ID 16641,18421 (which are legit invoice IDs)
In summary, works if I pass one invoice ID, fails if I pass two or more.
Any ideas? Or do you reckon this is now a post for the BIP forum?
Kind regards.

Wildcard search with catsearch on Oracle 10g

Wildcard search problem is being discussed many times, however the solutions provided did not solve the problem.
I am using catsearch to take its advantages and return results at a faster rate. Aim is to simulate a like '%abc%' using catsearch in 10g.
Following are the steps to reproduce the problem.
CREATE TABLE test
   (name VARCHAR2(60))
INSERT ALL
INTO test VALUES ('VCL Master')
INTO test VALUES ('VCL Master S.')
INTO test VALUES ('VCL Master S.A. Compartment 1')
INTO test VALUES ('VCL MasterS.A. Compartment 2')
INTO test VALUES ('VCL Master., S.A.')
INTO test VALUES ('KCL Master Corp.')
SELECT * FROM DUAL
begin
ctx_ddl.create_preference('Jylex', 'basic_lexer');
ctx_ddl.set_attribute('Jylex','SKIPJOINS','.-=[];\,/~!@#$%^&*+{}:"|<>?`§´¨½¼¾¤£€©®''');
end;
begin
    Ctx_Ddl.Create_Preference('wildcard_Jylex', 'BASIC_WORDLIST');
    ctx_ddl.set_attribute('wildcard_Jylex', 'wildcard_maxterms', 15000) ;
end;
CREATE INDEX test_inx ON test(NAME)
INDEXTYPE IS CTXSYS.CTXCAT
PARAMETERS('STOPLIST CTXSYS.EMPTY_STOPLIST
LEXER     Jylex
WORDLIST wildcard_Jylex')
problem1:
select * from test where catsearch(name, 'CL Mast*', NULL)>0 --- no results returned
problem 2:
when I run the following query on the actual column of my table with 3 million records,
select * from XXXX where catsearch (NAME, 'VCL Master S*', NULL) > 0
I get the following error.
DRG-51030: wildcard query expansion resulted in too many terms
I have used () and "". Did a lot of R&D and still I am not able to a solution that resolves both of the problems.
Suggestions will be much appreciated.
Thanks.

This post has nothing to do with Oracle Objects. Perhaps some moderator will move it to the Oracle Text sub-forum/space, where it belongs.
Your search for 'CL Mast*' did not find any rows because there aren't any rows that match that criteria. If you want to return rows that have that string, then you need to add a leading wildcard. Technically CTXCAT indexes and CATSEARCH do not support leading wildcards, but you can use two asterisks as a workaround, so you can search for '**CL Mast*'.
Your wildcard_maxterms is set to 15000, so if there are more than 15000 words that begin with 's' in your 3 million records, then it will result in an error. If you upgrade to Oracle 11g, then you can set the wildcard_maxterms higher or to unlimited by setting it to 0, but that may cause your system to run out of memory. Most applications trap these errors and return a simple message to the user, indicating that the search for s* is too broad and to narrow the search.
I would use a CONTEXT index with CONTAINS instead of CTXCAT and CATSEARCH. It supports leading wildcards and you can index substrings for faster searches. If you want it to be like the CTXCAT index then you can make it transactional.

Fix for SOLR searches beginning with wildcard?

All, I am having problems finding clear answers on if the above was corrected in ColdFusion 10.
I can't get my head around the idea of SOLR not allowing search criteria to begin with a wildcard. I've seen a solution for reverse wildcard searching, which is great as long as I specify criteria for which I know the ending letters. For example, if I am looking for all entries ending in "ing", I could do a search on "*ing", using the reverse wildcard to find "gni*". I have yet to see, or come up with, a solution for a SOLR search with wildcards in the start and end of the criteria. For example, lets say I am looking for any word with "fus" in the middle, such as "confusing" or "perfusing" or "profusely". I would want to do a search such as "*fus*". From what I understand thus far, this cannot be done in SOLR?
Thanks,
Tom

ColdFusion will support whatever Apache solr supports as it is the underlying engine we are using.
And Solr does support it: http://lucene.apache.org/solr/api/org/apache/solr/analysis/ReversedWildcardFilterFactory.h tml
I think this is an egregious hack, but still, it's the way they've chosen to support it.
Solr technically disables support of leading wildcards by default in the traditional query parsers due to concerns about query performance since it tends to select a large percentage of indexed terms.
Be that as it may, this should be my decision, as the maintainer of the index, not your decision to blanketly disallow it. If it's available, then one can use it if one choses, or not use it for the reasons you cite. If you blanketly disallow it, you're removing the ability for me to make that decision.
It's also a bit of a backwards compat issue, innit? Verity allowed leading wildcards.

Is there any problem going on with google search embadded in firefox or is it with firefox?

i m can't search any thing via Google search embedded to Firefox, rather i have to open google.com and then search, i was wondering is there somthin wrong with Firefox or its wrong with google itself. im facing this issue since morning. Time-morning IST.

There's a general iCloud problem now. See: http://www.apple.com/support/systemstatus/

The problem is with Google search in FF 5.0.

The problem is with Google search in FF 5.0. Everything was fine until I upgraded to FF 5.0. Now, I enter a text and search, I get results, no problem so far. Then, I want to edit the search text slightly to fine tune, so I click in the search bar, that is it, the original search text that was still there in the bar just disappears. I tried this with IE, it works fine, problem is only with FF. Any suggestions?

The Operator said i go to the "premium" site, on which a sepparate billing of traffic,several times more expensive than usual. it happens only when i use google search in safari. When i open the same site in the browser without using google search, traffic is billed according to tariff

Problem with Binary search statement

Hi,
I have problem with reading the internal with Binary search.
I have two internal tables BSAS and BSIS. In BSAS I have 1,200,000 line items and BSIS 500,000 line items. I need to delete the line items if BSIS-BELNR NE BSAS-AUGBL.
I am using the following code :
    LOOP AT gt_bsas .
      READ TABLE gt_bsis WITH KEY bukrs = gt_bsas-bukrs
                                  belnr = gt_bsas-augbl
                                  gjahr = gt_bsas-gjahr.
      IF sy-subrc NE 0.
        DELETE gt_bsas.
        CLEAR gt_bsas.
      ELSE.
     endif.
endloop.
By this execution of the loop is taking long time. If I use the binary search it is fast but result is not correct.
Please suggest me, how to resolve this issue.
Thanks,
Sri.

Try this way:
LOOP AT gt_bsas .
<b>SORT GT_BSIS BY BUKRS BELNR GJAHR.</b>
READ TABLE gt_bsis WITH KEY bukrs = gt_bsas-bukrs
belnr = gt_bsas-augbl
gjahr = gt_bsas-gjahr
<b>BINARY SEARCH.</b>
<b>IF sy-subrc eq 0.</b>
****Do Nothing.
ELSE.
<b>DELETE gt_bsas sy-tabix.</b>
CLEAR gt_bsas.
endif.
endloop.
1. Also make sure that the KEY mentioned in READ statement follows the same seqeunce of gt_bsis structure.
Thanks,
Santosh

Planning problems with russian language during refresh application

Hello all ))

Recruiting problem with the candidate search by trex with questionnaires

Hi Gurus,
I am trying to search candidates using trex in recruiting by candidate_questionnaires but the trex does not show any result. How can I solve it?
When candidates register theirselves on internet, they complete questionnaires that I have added in the apllication wizard.
But the problem starts when I want to search candidates by the answers that they have complete in this questionnaire. So I select the criteria search candidate questionnaire, then I select the questionnaire and then the answer and I run the searh. I know that the results shown are always about others requisitions and not the one that I am doing the search. But in my case candidates are assigned in other requisition with the same process template so I do not know where is the problem, because other sort of search works fine. This is the only one that it does not work.
In addition, I have run the report RCF_CHECK_SEARCH_SETTINGS but the result is that all the parameters are fine except that I have not implement the badi HRAHAP00_FOLLOW_UP_SES. May I have to implement?
Moreover I have seen that when I select the answer to search, any operator (element of selection mask) is assigned but I have read that it is correct because I am using the search profile "int_cand" with the category "candidate_document" that it use in the mask search candidate_questionnaire.
In conclusion, I don't know how I can solve this problem with trex? Any idea?
Thanks in advance,
Juanjo Garcin.

I've already done it.
Do you think this will help?
I doubt that Apple will listen to us. Users with a problem that occurs quite a lot.

Problem with ALV search help Dictionary Search Help

Hello experts
I have a problem with ALV search help.
I use DDIC table ZXXX with text table ZXXX_T. I created DDIC search help form table ZXXX. In my WD application, in context on COMPONENTCONTROLLER i set on attribute: 'Input help mode' as 'Dictionary Search Help' and in 'Dictionary Search Help' I pass name of new created DDIC search help.
I create a input field from that atrribute and search help works fine (there was a value and description for value from text table). So I created ALV witch contains that attribute too.
Next I set column for this attribute in ALV as editable but on Serch help for this collumn I have only value. I DON'T HAVE TEXT DESCRIPTION FOR VALUE.
Please help me and tell me what I do wrong?
Miko

Hello,
Thank's for your help. I create DDic Search help for all fields from my ALV. Next I changed 'TYPE' for all ALV fields in COMPONENTCONTROLLER from ZXXX-Zfield to Zfield, and I changed 'Input help mode' from 'Automatic' to 'Dictionary Search Help'. Now I see Value and Description for value in Search Help in my ALV.

Restrict access with object F_LFA1_BEK - problem with F4 search

Hello,
we want to restrict access to some vendor accounts, which can be shown with transaction FK03 for example.
There is an authorization object F_LFA1_BEK, which can be maintained in the special vendor accounts in field authorization group.
A user with authorization for vendor account with authorization group ZZZZ in it can see all vendors with authorization group ZZZZ and all vendors with no authorization group. But he can't see vendor accounts with authorization group YYYY. To this point, it's ok.
If the user uses the F4 search help he is able to see the vendor accounts with authorization group YYYY too. And this is the problem - the user should not see these vendor accounts. With this option user is able to see address data of a vendor account he should not see.
Is there any possiblity to solve this problem?
Regards,
Julia

I don't know the current status, but this is being looked into generally as it is not only limited to the F4 on LFA/B/M1.
As you only access the name and some attribute data which you can display, it is not necessarily critical and there is no transaction data involved.
Good news is that the BAPIs for search help make these same granular checks which you are expecting.
If I hear something further about these developments I will let you know.
Cheers,
Julius

Search&Replace with wildcard?

I always use search and replace with Homesite but I wonder if
there is a way of using a wildcard? I often want to replace text at
the beginning and end of variable text. I mean, if I have this:
<h3>First text</h3>
<h3>Second text here</h3>
What I'd like is, using the * as a wildcard, is to use
something like this:
Replace <h3>*</h3> with <h2>*</h2>
Any ideas? Thanks

you can use the extended search/replace with regular
expressions to do this.
So for example. Bring up the Extended Replace (Ctrl + Shift +
R)
And in the Find box, put:
<h2>(.*)</h2>
in the Replace with box, put:
<h3>\1</h3>
note: \1 is the first match returned by the regular
expression

SOA 11g Bundled EM - search instances with wildcard?

Hello~
My apologies if this isn't the right place for this post... it's on a bit of a grey line between SOA and EM.
Anyway, in the EM that comes bundled with SOA Suite 11g, under:Farm > SOA > soa-infra > [partition name] > [composite name] > Instances (tab) the user can search the audit trail entries for instance details that are still in the database.
My question is, if I am searching by Name (which is a field that can be set by calling setInstanceTitle() in a Mediator/BPEL object), is it possible to do that search with a wildcard?
I've tried: myquery% and myquery* but neither give the expected results (all instances with a Name that starts with "myquery").
Thanks in advance for your feedback,
- Nathan

Hi, Damien~
Thanks for the feedback. I'll go ahead and mark your answer correct and the question as answered.
...though, if Oracle happens to be listening, it seems to me that the ability to search instances from EM using wildcards would be a great feature to add to SOA 11g.
