  • Oracle iRecruitment: Keyword Search within Resumes using Oracle Text

    Dear All,
    As per my understanding (and Note: 247064.1) simple Keyword searches can be performed in iRecruitment if oracle Text is installed. However searching for Keywords within resumes is not possible using Oracle Text and is possible ONLY if Resume Parsing is enabled via a third party (non-oracle) service provider.
    Can you please let me know if my understanding is correct and if not provide further inputs on this.
    Thanks,
    Subrat

    Got this confirmation from Oracle via SR:
    Resume searching is independent of resume parsing and not required to search resumes.
    Oracle Text is the text engine that allows you to search documents using content-based queries. Oracle Text allows you to upload documents, search documents, parse resumes, etc.
    Hence to conclude - Installation of Oracle Text will allow Keyword Searches on resumes.
    Thanks,
    Subrat

  • Using oracle text in apex report search

    I am trying to use oracle text in apex, integrating it in an existing application. The idea is that it will allow to do a search in bigger textfields. Thats how I want it to get to work. In one of the oracle packaged applications oracle text is used as well, so I will have a look to that as well. I've addapted this search. I've added
    AND t. contains(oplossing, :P15_OPLOSSING)
    AND t.contains(sleutelwoorden, :P15_SLEUTELWOORDEN)
    That didn't work, so I changed those two to:
    AND t.oplossing = (t.contains(oplossing, :P15_OPLOSSING)>0)
    AND t.sleutelwoorden = (t.contains(sleutelwoorden, :P15_SLEUTELWOORDEN)>0)
    which didn't work either, which I expected to be the case. Clearly I'm not doing it correctly, I intend to look it up tonight in the packaged applications as I do want to findt it myself to.
    But does anyone can give a hint, on what I am doing wrong ?

    I have worked it further out now, and looked at the search of the packaged application. It turned out to be a pl/sql block . I used what I found in there to adapt the previous search. I added the following:

    OR (CONTAINS(t.sleutelwoorden, :P15_SLEUTELWOORDEN)>0)

    OR (CONTAINS(t.titel,:P15_SEARCH_T_O_S)>0 AND
         CONTAINS (t.oplossing, :P15_SEARCH_T_O_S)>0 AND
         CONTAINS(t.sleutelwoorden, :P15_SEARCH_T_O_S)>0 )
    oplossing means solution
    sleutelwoorden means keywords
    titel means title
    Yet this doesn't work yet. It gives an error message:
    failed to parse SQL query:
    ORA-01719: outer join operator (+) not allowed in operand of OR or IN
    I've tried adding the addition in a different place, yet that gives the same error message. I'm not sure now.

  • Using Oracle Text to search through WORD, EXCEL and PDF documents

    Hello again,
    What I would like to know is if I have a WORD or PDF document stored in a table. Is it possible to use Oracle Text to search through the actual WORD or PDF document?
    Thanks
    Doug

    Yes you can do context sensitive searches on both PDF and Word docs. With the PDF you need to make sure they are text and not images. Some scanners will create PDFs that are nothing more than images of document.
    Below is code sample that I made some time back to demonstrate the searching capabilities of Oracle Text. Note that the example makes use of the inso_filter that is no longer shipped with Oracle begging with Patch set 10.1.0.4. See metalink note 298017.1 for the changes. See the following link for more information on developing with Oracle Text.

  • Using Oracle Text for searching with UCM 10g

    I am using Oracle text with UCM 10gR3 and Site Studio 10gR4 and I am trying to sort the search results by relevancy and to also include a snippet of the retrieved document. I have the fields that the SS_GET_SEARCH_RESULTS service returns but the relevancy score is always equals 5 and the snippet contains characters such as < idcnull, /p, etc., which you can see are XML/HTML/UCM tags but which result sin even more strangeness in the snippet if I try to remove them programmatically.
    I have read the Oracle Text documentation and there appear to be ways you can configure Oracle Text but I am not clear at all on what I can do from UCM. It looks like the configuration is either done in database tables or in the query itself, neither of which are readily configurable to me.
    Is anyone experienced in this or know of any documentation this might help?
    Bill

    Hi
    If I remember correctly then this issue was seen with an older version of OTS component and Core Update patch / bundle . Upgrade the UCM instance with the latest CS10gr35 update bundle patchset 6907073 and also upgrade OTS component from the same patchset .
    Let me know how it goes after this .
    Thanks

  • Searching using Oracle Text instead of LIKE '%'

    Hello all,
    I hope you help me in this:
    I have a table looks like this
    create table subscribers (
    id numer(10),
    first_name varchar2(30),
    father_name varchar2(30),
    grandfather_name varchar2(30),
    last_name varchar2(30))
    The application is built using Oracle Forms. Many times, the end users are not so sure of the spelling of the name, therefore they use the "%" wildcard with name fields. This will be reflected to the queries the application will send them to the Oracle Server.
    We have the following queries
    1) select *
    from subscribers
    where last_name like '%family_name%';
    2) select *
    from subscribers
    where last_name like 'family_name%';
    3) select *
    from subscribers
    where last_name like '%family_name%' and first_name like '%first_name%';
    4) select *
    from subscribers
    where last_name like 'family_name%' and first_name like 'first_name%';
    As well as searching on the father_name and grandfather_name fields. But most of the search are on the first_name and the last_name.
    These queries are killing the server since we have millions of records. BTree indexes will not help here because of the LIKE and the "%"
    I am thinking to use Oracle Text here, but I am not sure whether I have to go for a CONTEXT index on each individual column, or I can use the MULTI_COLUMN_DATASTORE indexing.
    Any idea will be appreciated

    The ctxcat index and catsearch operator are generally intended for usage with one text column and one or more columns of structured data. You would have to pick just one of your columns as the text column and the others as structured columns. I would be more inclined to use the multi_column_datastore with a context index and contains operator, so that you can search all of your columns as text columns.

    You could use an Oracle Text context index with a wordlist to speed up substring searches and return all rows that match any of your criteria, combined with a case statement to provide a ranking that can be ordered by within an inner query, then use rownum to limit the rows in an outer query.  You could also use the first_rows(n) hint to speed up the return of limited rows.  Please see the demonstration below.  If you decide to use Oracle Text, you may want to ask further questions in the Oracle Text sub-forum on this forum or space or whatever they call it now.

  • Using Oracle Text in Oracle XML DB .

    Hi all ,
    The idea is simple ,i need to index all stored files in Oracle XML DB and the index should stay in Oracle DB . Using some 3 party index software is also possible but you need to write a mapping to move the index file in Oracle DB .
    So i thought of using Oracle Text but i am not sure about how to retrieve such a document from Oracle XML DB , let me say over ftp or http ? . And if these documents are password protected -> how can Oracle Text allow this ?

    [11gR2 XMLDB Developers Guide -- Full-Text Search over XML Data|http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10492/xdb09sea.htm#i1006756] would be the first place to start.
    For document display, there a bunch of potential solutions, you can look at [XML DB Repository|http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10492/xdb03usg.htm#insertedID18], or the Text Application Developers Guide [Presenting Documents in Oracle Text|http://download.oracle.com/docs/cd/B28359_01/text.111/b28303/view.htm#i1006687] .
    Password protected documents can't be indexed using the auto_filter.

  • Oracle Text: How to add/get stopwords list when using Oracle Text world lexer?

    I have a use case that we currently use Oracle Text World Lexer to index and search multilingual documents. As we know that World Lexer does the language auto detection. I would like to know the following questions:
    Is there anyway I can get the current document's language that Oracle Text detected?
    Is there anyway to get the language's stopwords list?
    Any thoughts and points will be appreciated.
    - Charles

    1. If you're using 12c, you can use ctx_doc.policy_languages. (https://docs.oracle.com/database/121/CCREF/cdocpkg011.htm#CCREF24102)
    2. If you want multiple stoplists based on each document's language, you have to use the multi-lexer. For world_lexer, there is one stoplist; since the stoplists are somewhat dynamic (you can add but not remove them), the most accurate way to fetch the list is using ctx_report.describe_index or ctx_report.create_index_script and parse the report.

  • Using Oracle Text to Data Mine

    Can someone provide me with an idea of how to Data Mine with just using Oracle Text and not the data mining option. I need to search a column of customer complaints and then put it in a category based on that. It would be best if the categories were auto generated. It has to be done in PL/SQL.
    Thanks,

    You cannot have the categories created automatically without data mining. However, if you are willing to create the categories and queries that determine them, then you can do it with just Oracle Text. I posted an example on the 2nd page of the following thread:

  • Document management system using oracle text

    i plan to create document management system using oracle text with following features
    1) document comparision
    2) document search
    and more...
    can oracle text be used to display documents of various formats by converting them to HTML. and can search keywords be highlighted in the document.
    please help!

    Have you ever considered doing this in Oracle Application Express (free on top of the Oracle database)? How about something like:
    http://download-west.oracle.com/docs/cd/B31036_01/doc/appdev.22/b28839/up_dn_files.htm
    Index the files using the CONTEXT index, and perhaps the docs' meta with it using the Oracle Text MULTI_COLUMN_DATASTORE, and then when you write your query for a report on the documents include a search string.
    I've created a number of APEX-based document management systems and it is quite easy once you get the hang of using this environment. I suggest looking at some of the tutorials/how-to documents and you'll be on your way quickly.
    Start with the upload application. Once you can get your documents in, create a report that shows everything except the document. Verify all of this works correctly.
    Add some "items" to the page for the report, and include them as bind variables in the where clause.
    After that, add your Oracle Text index to the database, and toss in a "text-field" item to the APEX page. Modify your report query, adding the CONTAINS clause, and use the newly created item as a bind variable. There's your keyword search.
    Linking to Oracle Apps is done through API's and may be over database links.
    Hope it helps. Though not a step-by-step how to document, this should point you in the right direction. Get familiar with APEX as that covers most of what you described.

  • Problem with blob column index created using Oracle Text.

    Hi,

    I wonder what's wrong with it.
    My user has been granted the ctx_app role and I have other tables that store plain text which I use Oracle Text are fine. I even output the blob column and save as pdf file and they are fine.
    However the database seems like not indexing my blob column although the index can be created without error.
    Please advise.
    Really appreciate anyone who can help.
    Thank you.

    The situation is I have already loaded a few pdf document into the table's blob column.
    After I create the Oracle text index on this blob column, I find the system generated index tables listed in my earlier posting are empty, except for the 4th table.
    Normally we'll see words inside the table where those are the words indexed by oracle text on my document.
    As a result, no matter how i search for the index using select statement with contains operator, it will not give me any result.
    I feel weird why the blob is not indexed. The content of the blob are actually valid because I tested this by export the content back to pdf and I can still view and search within the pdf.

  • NEAR operator alternative when not using. oracle Text ?

    hi,
    I'm working on a project where i would need a Oracle Text 'NEAR like' operator ...
    here is my scenario ...
    in db we have Customers ... and every customer has some criterias like different search words( names, towns,cars,etc...) so for every customer i can create an SQL query out of criterias . ....
    now .... we can have a criteria like. ...... WHERE fulltext like 'john%'. or even distance search line NEAR inside CONTAINS. ... but then the Oracle text index is needed .....
    the only tAble on which Text index is created is our storage table that holds more then 4mil records and growing...
    my question is ... is there any way to have a query that would do the same thing as NEAR but without Text index ?
    here is how I start ....
    I get full newspaper article text from our OCR library ......
    then i need to check customer's criterias against this text to see which article is for which customer and then bind the article to the customer
    I could do it without Oracle using RegEx , but criterias can get really complicated ... like customer wants only specific MEDIA, or specific category , type , only articles that are from medias that are from specific country etc ... and many more different criterias ... and all this can be wrapped inside brackets with ANDs, ORs, NOT. ....
    So the only way to do it is to put it in Oracle and execute the correct query and let Oracle decide if the result is true or false .... but due to NEAR operator I need Oracle text ...
    So if I decide to first insert article into our storage table which has Oracle text index to be able to do the correct search .... how fast will this be ????
    will the the search become slower when there are 6mil records ? I know I can use FILTER BY to help Text index to do a better and quicker seach ... and how to optimize index ....but still
    I'm always asking my self..... why insert the article in a table where there are already 6mil articles and execute query when I only need to check data on one single article and. i already know this article ...
    I see two solutions :
    - if there is alternative for NEAR without using Oracle text index then i would insert data into temporary table and execute query on this table..... table would always contain only this one article. maybe one option would be to have one 'temp' table with Oracle text index in which i insert this one article and with help of Oracle text based on this one article do the search , and then maybe on a daily basis clear index ..... or when the article is removed from the table ... but this would mean having two Orcle text indexes, cause we already have Oracle text index on our storage table anyway....
    - another is to use Oracle text index and insert it into our storage table and hope for the best quick results ....
    Maybe I'm exaggerating and query like WHERE id=1234 and CONTAINS(...). will execute faster then I think
    If anyone would have any other suggestion I will be happy to try it ..
    thanks,
    Kris

    Hi,
    this is to my knowledge not possible. It is hard for Oracle to do, think about a table with many rows, every row with that column must be checked. So I think only a single varchar2 is possible. Maybe for you will a function work. It is possible to give a function as second parameter.
    function return_signup
    return varchar2
    is
      l_signup_name signup.signup_name%type;
    begin
      select signup_name
      into l_signup_name
      from signup
      where signup_id = 1
      and rownum = 1
      return l_signup_name;
    exception
      when no_data_found
      then
        l_signup_name := 'abracadabra'; -- hope does not exist
        return l_signup_name;
    end;Now you can use above function in the contains.
    select * from user_history_view users --, signup new_user
    --where new_user.signup_id = 1
    where contains(users.user_name, return_signup)>0;I didn't test the code! Maybe you have to adjust the function for your needs. But it is a idea how this can be done.
    Otherwise you must make the check by normaly check the columns by simple using a join:
    select * from user_history_view users, signup new_user
    where new_user.signup_id = 1
    and users.user_name = new_user.signup_name;Herald ten Dam

  • Parsing the word file using oracle text having tables within it............

    Hi,
    I was going through this document.Actually I am going to implement something like full text search functionality in our system.
    We get the info as .doc file.
    Earlier what we used to do is, we used to parse the file and store it into the database and then searched using PL/SQL.
    But what I understand from this article that this can be done using oracle text also.
    One concern is that whether the oracle text is able to parse the .doc file having tables embedded within it.
    Please let me know about this.(Whether oracle text will be able to parse the files having tables embedded within it).
    I am attaching an example file for this.
    Please let me know about this as early as possible.

    Yes Oracle Text have this capability. Use AUTO_FILTER or USER_FILTER to create index
