Reflections on 3D Text query

Hi,
Via the new shape from layer I am able to create reflection on sphere by loading the environment with a texture and playing around with the reflection,gloss,shine.
However I'm having issues doing the same on 3d text (created via reppousse/text layer), the reflection on the front Inflation material is just not appearing
How do position the reflection?
CAn you scale the image that you set for the reflection image (environment)?
Thanks in advance
Steve

Well after playing around with this a long time I think I manage to work it out.
I mention this just in case it might help someone else out.
As I said once I enable reflections on the front inflation of the 3d text (setting a image to the environment and raising the reflection value setting) I could not understand why the reflection was so blurred and pixelated no matter how much I rotated it
The reason was by default I'm apparently looking at my 3d object with camera well zoomed out. I went through the process of scaling my camera back and zooming into my object with the object scaler tool. Of course the wire frame 3d object still stays the same size on screen if you do this
However gradually the reflected image became sharp and with reflection setting set to 100% it acted like a mirror exactly what I expect. Horray!!!
Now by looking at my object in the 3d view with my 3d plane visible it is hard to see how far or near the object is is relation to Camera distance and the scale of the 3d object. Is there some indication in this view that I'm not seeing?
Anyway hope it helps
Steve

Oracle Text query: Escaping characters and specifying progression sequences

How can I combine the escaping of a search string and the specification of progression sequences within an oracle text query
so that in all cases the correct results are delivered (see example below)?
The scenario in which to use this is the following:
+ Database: Oracle Database 10g Enterprise Edition Release 10.2.0.2.0
+ Requirement: Hitlist of results ordered by score whereby the different part within
the result list are specified using progression sequences within oracle text query
Example:
create table service_provider (
id number,
name_c varchar(100),
uri_c varchar(255)
insert into service_provider values (1,'ABB Company Mgmt','http://www.abb-company-mgmt.de');
insert into service_provider values (2,'Dr. Abbas Ming','http://www.dr-abbas-ming.de');
insert into service_provider values (3,'SABBATA United','http://www.sabbata-united.de');
insert into service_provider values (4,'ABB','http://www.abb.de');
insert into service_provider values (5,'AND Company Mgmt','http://www.and-company-mgmt.de');
insert into service_provider values (6,'Dr. Andas Ming','http://www.dr-andas-ming.de');
insert into service_provider values (7,'SANDATA United','http://www.sandata-united.de');
insert into service_provider values (8,'AND','http://www.and.de');
Query 1: works correctly in this case

produces ORA-29902, ORA-20000, DRG-50901 because AND is a reserved word in oracle text
So we need escaping ...

order by score(1) desc, this_.NAME_C

delivers
76     4     ABB     http://www.abb.de
76     1     ABB Company Mgmt     http://www.abb-company-mgmt.de

Oracle text query

Hi,
I have a View object with various attributes (eg, name1, name2, name3, address1, address2, address3 etc). A query/table component based on this view object works just fine. However, I wish to replace name1, name2, name3 and other attributes in the query with just 'name'. These attributes are still to be shown in the result table. This new 'name' attribute will be used in an Oracle Text query clause, instead of individual searches on each attribute.
My plan was to simply make the various name1, name2 etc attributes non-'queryable' in the View def to hide them from the query. Then I'd add a transient 'name' attribute. My hope was, that I could override the getWhereClause() in the ViewObjectImpl and simply tack on the oracle text clause to the WHERE (example below):
WHERE CONTAINS (
SOMECOLUMN,
            '<query>
   <textquery lang="ENGLISH" grammar="CONTEXT">TRANSIENT_ATTR_VALUE
..... Oracle Text query grammar stuff here .... </query>') > 0How do I access the transient value in the ViewObjectImpl to add the above SQL? Or am I going about this in completely the wrong way?
thanks,
Barry.

DRG-50901: text query parser syntax error

Why?
There is a TEXT index on the summary column:

Because the exclamation mark ("!") is a reserved operator, meaning soundex, and must appear before the word it applies to.

Declare a text query

If I have a text query in visual studio EXEC DCC_SPP_GetPeopleByDepartment @Department
how can i declare the @Department to be varchar (8000) ?
I tried declaring it in the stored procedure, but when I deploy the report, the query fails as it's looking at the text query.

Try :
EXEC DCC_SPP_GetPeopleByDepartment Convert(varchar(8000),
@Department)

Checking text query validity without actually running the query: ideas?

Hi,
I would like to implement a sort of function that does a preliminary check on the validity of the search string and ideally this function should work with both CTXCAT and CONTEXT indexes (and grammars).
Initially I thought that CTXQUERY.EXPLAIN function could do this for me, but, unless I am missing something, it only works with CONTEXT indexes and it doesn't accept a string containing a text query rewrite using CTXCAT grammar (it throws DRG-11119: operation is not supported by this index type).
Plan B would be to create an empty table with a CONTEXT index and then run the query either with the CONTEXT grammar or the CTXCAT grammar via query rewrite and if the query runs, returning no rows, presumably fast enough for this purpose, then the query string is assumed to be valid.
What I don't like much about plan B is the need for an additional table plus the "dummy" context indexes just to perform the parsing of the text query, but so far I didn't come up with more brilliant ideas.
Any thoughts?
Am I missing something that does the magic without hassle?
Thanks
Flavio

Under normal circumstances I wouldn't do this, as you say I'd just run the query and catch the error, but I need to do this inside a report refresh performed via AJAX (using Oracle Apex) and the catch is that when such refresh fails owing to a syntax error, the partial refresh mechanism of APEX becomes broken, so even if you amend the query and submit a new valid string, it won't show up any more.
That's why I need to be sure that the string is valid before running the query, hence the syntax checking function.
The google-style parser sounds interesting, may be I can try to implement it in a future release of my app!
Thanks
Flavio

Text query parser issue

Hello guys,
I rather need an advice and my experience with the Oracle forums has always been auspicious.
I am using jDeveloper 11gR2 and Oracle database 11.2.0.1. Running the following query I have a view object based on that query and a search form with results table.
SELECT
SEEKER.SEEKER_ID SEEKER_ID,
SEEKER.CV CV,
SCORE(1)
FROM
SEEKER
WHERE CONTAINS(CV, '<query>
<textquery lang="ENGLISH" grammar="context">' ||
GET_RELATED_CATEGORIES(:keyword) ||
'</textquery>
<score datatype="INTEGER"/>
</query>', 1) > 0
GET_RELATED_CATEGORIES is a function which returns concatenated strings querying some semantic data in my database. The problem is when GET_RELATED_CATEGORIES returns null the "text query parser" is throwing an exception (that is how it is supposed to act).
I am asking for any suggestions for the implementation of that functionality and will be really grateful. Shall I export the whole query in a remote procedure and maybe call it as a web service or there is any other better solution (maybe some checks).
Thank you in advance!

I see two possible ways you can try.
1. cause the function in a way that no null value is returned (return an empty string '')
2. put a nvl (get..., '') around the function

Full text query across multiple columns

In the SQL Server, when you do the full text query, you can specify multiple columns, e.g.
FREETEXT ( { column_name | [b](column_list) | * } , 'freetext_string' [ , LANGUAGE language_term ] )
CONTAINS ( { column_name | [b](column_list) | * } , '< contains_search_condition>' [ , LANGUAGE language_term ])
Where,
column_list Indicates that several columns, separated by a comma, can be specified...
* Specifies that all columns in the table registered for full-text searching should be used to search for the given contains search condition. The columns in the CONTAINS clause must come from a single table...
That makes full text query cross multiple columns very convenient. Are there any mechnisms in Oracle to do the same thing?
Thanks in advance.

Thanks for your reply.
I knew that you could build full text index for the multiple columns using Oracle Text. But that does not solve my problem, which is how to build the query to search multiple columns at once. Say, I have columns firstname, lastname, address, and email in the table customers. I want to get the results that ANY column contains 'bob'. In SQL Server, I can do
select * from customers where contains(*, 'bob')
that is. But for Oracle, I have to do
select * from customers where contains('firstname', 'bob') or contains('lastname', 'bob') or contains('address', 'bob') or contains('email', 'bob')
Can you imagine if I have many columns in many tables and I have to do the query against all columns in all tables? I have to dynamically get all the columns and then build the query string.
So, any better solutions?

SharePoint key word query, how does the "Query Text" query special character in a query variable?

I have a no code sandbox solution, in a content by search web part, I want to return pages from the library except the page I am visiting.
I have 2 pages:
Page A, the title is: Page title without special character
Page B, the title is: Page title with special character "a b c d ..."
And then I use Title<>{Page.Title} in the query text of the CSWP.
While I visit Page A, the CSWP returns Page B, it works as expected.
But while I visit Page B, the CSWP returns nothing, expected result should be Page A. I just consider, whether the special characters in the Title of Page B breaks the query text.
I can not find similar topics in the forum, Does anyone have idea?
Many thanks!

Thank you for your feedback, Daniel.
I have some updates, and found the root cause: if the field value contains special characters, the CSWP will not render the double quotation marks around the field value.
View the page html source, and then find the text "QueryModification", you will see what happen:
Query Text Input: Title<>{Page.Title}
1. While the page title is "Test Page 1" (without special character), the rendered query text is
Title<>\"Test Page 1\". It works as expected.
2. While the page title is "Test-Page-1" (with special character "-", of cause we have more special characters on production), the rendered query text is
Title<>Test-Page-1. The double quotation marks are not rendered by the CSWP, so the query text are broken. It does not work as expected.
If I make the query text as Title<>"{Page.Title}"
1. While the page title is "Test Page 1", the rendered query text is
Title<>\"\"Test Page 1\"\". It does NOT work since the
quotes are duplicated (no sure why CSWP duplicates the quota mark),
2. While the page title is "Test-Page-1", the rendered query text is
Title<>\"Test-Page-1\". Quotes are correct, but it does NOT work as expected still.
The expected rendered query text (view from the html source) should be
Title<>\"Test\\\-Page\\\-1\". (Here is test url: <a href="http://server/_api/search/query?querytext='Title<>"Test%5c%5c%5c-Page%5c%5c%5c-1"'&rowlimit=10">http://server/_api/search/query?querytext='Title<>"Test%5c%5c%5c-Page%5c%5c%5c-1"'&rowlimit=10)
From the above information, I can say the CSWP not handle the special character correctly ("\" is not inserted before any special charactor).
Is there any setting in CSWP can be used to resolve above problem?

"MS" reserved word in oracle text query?

Wondering if anyone has run into the string "MS" behaving as a reserved word in oracle text queries. For example, this specification returns all records from Texas:
'<query>
<textquery>
<progression>
<seq> TX WITHIN CUSTOMER_STATE </seq>
</progression>
</textquery>
</query>'
But this one does NOT find any results for Mississippi:
'<query>
<textquery>
<progression>
<seq> MS WITHIN CUSTOMER_STATE </seq>
</progression>
</textquery>
</query>'
I've confirmed we have data that should match, and I've tried escaping it with the sequences as described in the SQL docs (I've tried single quotes, pairs of single quotes, braces, and combinations of those) . And trying to find info on the web is tough since all web queries that contain 'MS' bring back tons of Microsoft-relevant information.
Can anyone nudge me in the right direction for a better google-search, or some materials in these forums (my initial searches here didn't turn anything up either).
Thanks for any feedback!

Oracle Text Query taking too long

When we run a query:
select docid from Tbl1 where contains(doc,'queryterm',1)>0;
on 2 million docs it runs in <2 seconds
When we run an insert into another table based on a search:
insert into Tbl2 (col1,col2) select 10,col2 from Tbl1 where rowid<2000; (10 in the select statement is a constant)
it runs in <2 seconds
Here's the kicker:
insert into Tbl2 (col1,col2) select col1,col2 from Tbl1 where contains(doc,'queryterm',1)>0;
it runs in 60 seconds and produces ~2k rows
Is there any hint that we can use to fix this?
TIA!

We've looked hard at the performance notes for Oracle Text, the Application guide and the FAQ on it.
We've dropped the index on the table being inserted, turn off logging and used the Parallel hint on the insert. There is still a bit of a disconnect between insert speed, select speed and both together. The index was built using the parallel option so the queries should be parallel if I understand the performance hints correctly.

Oracle Text Query of abbreviated word / name

I'm new to Oracle Text so please excuse the (probably) simple question. I want to be able to create a search that excludes (includes?) special characters and/or spaces between an abbreviated name. I'm not sure if it's possible but I would like to be able to return all of the below results if someone queried for "ABC" in one form or another.
Would this be something I'd add to a thesaurus? I see there is a STOPLIST but I'm not sure if there is the opposite of a stoplist.
Thanks in advance!

Indexes are case-insensitive by default, so let's ignore that.
You can make wal-mart and wal*mart match walmart by defining "-" and "*" as SKIPJOINS characters. However, you cannot make wal mart match walmart, other than by using NDATA.
NDATA does seem to work - any variation of wal mart walmart wal*mart and wal-mart do manage to match both walmart and wal mart. See example:
SQL> create table testcase (text varchar2(2000));
Table created.
SQL> insert into testcase values ('<nd>walmart</nd>');
1 row created.
SQL> insert into testcase values ('<nd>wal mart</nd>');
1 row created.
SQL> exec ctx_ddl.drop_section_group('tcsg')
PL/SQL procedure successfully completed.
SQL> exec ctx_ddl.create_section_group('tcsg', 'xml_section_group')
PL/SQL procedure successfully completed.
SQL> exec ctx_ddl.add_ndata_section('tcsg', 'nd', 'nd')
PL/SQL procedure successfully completed.
SQL> create index testcase_index on testcase(text)
2 indextype is ctxsys.context
3 parameters ('section group tcsg')
4 /
Index created.
SQL> select * from testcase where contains (text, 'ndata(nd, wal mart)') > 0;
TEXT
<nd>walmart</nd>
<nd>wal mart</nd>
SQL> select * from testcase where contains (text, 'ndata(nd, wal-mart)') > 0;
TEXT
<nd>walmart</nd>
<nd>wal mart</nd>
SQL> select * from testcase where contains (text, 'ndata(nd, wal*mart)') > 0;

<nd>walmart</nd>
<nd>wal mart</nd>
SQL> select * from testcase where contains (text, 'ndata(nd, walmart)') > 0;
TEXT

<nd>wal mart</nd>Edited by: Roger Ford on Jun 21, 2012 10:22 AM

Oracle Text query parser - sample code

I've posted a new entry on my "searchtech" blog which includes code for a "Google-like" query syntax parser:
https://blogs.oracle.com/searchtech/entry/oracle_text_query_parser
Currently it's just sample code, but if it goes down well we might include it, or something similar, in a future release of the product.
I'd very much welcome feedback on it, either here on the forum, or on the blog, or directly to me email address (which is included in the download file).
Thanks, everyone.

When I select the "open in browser" option for each now, I get formatted, readable code, which can easily be copied and pasted into a file without the extra txt extension, and I much prefer that. So, for me, that is a sufficient fix.
It seems like this is handy, virtually idiot-proof code, easy to create the package, easy to use it, and provides the Google-like search that users expect, without raising errors or producing unexpected results. Frequently, on the OraFAQ forums, where I am a moderator, when there are various ways to solve a problem and I provide a Text solution, the complaint is that it is too complicated to create all of the formatting to fix potential problems with user input. Your code solves that problem and I hope it will be included in the next version. If you don't mind, I will post an announcement in the OraFAQ Text forum with the permanent link that you provided.
