E-recruiting TREX search problem

Hi all,
I am experiencing a problem when searching from e-recruiting. Everything appears to be set up ok. Documents are being correctly indexed and all RFC connections are ok. Job RCF_PERIODICAL_SERVICES runs successfully.
When I do a test search from SKPR07 it only returns results if a space is entered between each letter of the search word. For example, if I search for the word 'skill' I get no results found but if I enter 's k i l l' it does return results.
A bigger problem is that no search results are returned from the user interface both for the external candidate and the internal recruiter.
As I say everything is being indexed correctly and I get successful results when performing a test search and a test index from the index category tab of the Search Server relation Monitor (transaction srmo).
Has anyone encountered this before or have any suggestions as to how this can be resolved?
Thanks in advance.
Jim

I got a response from OSS on this so it is now resolved.

  • E-Recruiting: TREX search %

    Hi,
    When a free text search is perfomed in E-Recruiting, there is a percentage match displayed beside each result. My client wants to know how that match % is calculated and what is the formula behind it.
    Thanks,
    Suresh

    Hello Suresh,
    the value is determined by the TREX engine. It is usually an issue in projects that if you have a back/white search criteria like gender which can be just male or female you get either 0% or 95,348264530245% instead of 0% and 100%. But that's how search engines work due to some fuzziness (google is nothing else here).
    Unfortunately search algorythms are very complex. So probably someone at sap developing the TREX core could explain it (if they open the technology and algorythms to the public) but I assume it needs some maths degree to follow the description ;o)
    I had this question in some of my projects. The answer "it's like google" usually worked!
    Cheers

  • E-Recruitment Candidate Search Problem

    Hi,
    I have done the Trex config properly. In table T77RCF_EXT_PUB  it is showing 'X' in published , therefore Ithink trex is configured properly. But still when I am goin for search  it is showing blank result. while there is data in database.
    When I checked the logs of  RCF_PERIODICAL_SERVICES then it is showing error in each run.
    Errors are -
    Serious error; see log
    The error occurred in program CL_HRRCF_SP_BUILDER===========CM003 line 115
    The incorrect HR object has the key 01NC50000596

    01nc50000981 has X in Published (latest one)
    01nc50000596 is blank in published (previous one)
    I am not understanding that where the problem occurs. Please help.

    Hi Sourabh,
    1.  First and foremost, try Re-Activating / regenerating the STANDARD classes in the PERIODIC SERVICES table. But before activating, try executing the class. If the class gives a dump that means thats the problem class. However, even if it does not give a dump, re-activate it.
    Start this activation process with the root class which i think in your case is CL_HRRCF_FRKWF_STORAGE. Try debugging the class and check where the exact point of error lies. If its another class within this class also try activating that sub-class. Everything depends on where the problem error occurs. Try executing that problem object independently and i am sure it will give a dump at some point.
    This is an INCONSISTENCY problem which often comes up during upgrade or installation.
    2.  Also, check the content server settings or whether the
    content server has been properly  configured. Maybe reconfiguring will solve the issue.
    But i am sure regenerating the objects will solve the issue

    Hello Sowmya,
    I feel that the custominzing in the table T77RCF_SCALES aer not perfect.
    there may be missing entries here For example :
    - No entry in Customizing table T77RCF_SCALES for scale type [A]
    - No entry in Customizing table T77RCF_SCALES for scale type [C]
    - No entry in Customizing table T77RCF_SCALES for scale type [W]
    - Customizing table T77RCF_SM_ASME contains no corresponding entry for
      SMASK_ID =0002

  • TREX search problem in collaboration room search

    Hi,

    Any ideas how to fix that?
    Regards,

    Hi
    i think the trex services in os is not started.
    Please do the following:
    1. Restart the TREX Service from the OS. In Windows go to Control Panel -> Administrative Tools -> Services. Look for TREX Instance XX
    2. Check if the system process TREXIndexServer(.exe) runs. In Windows just open the Taskmanager and look for the process.
    3. Go to the TREX log folder "\usr\sap\trex_61\trace". Check for errors in the file TrexIndexServer.XXXXX.XXX.trc

  • TREX search error

    We are getting an intermittent problem when we do a search from our KM iview.  When we put in a search string it for the most part comes back with the appropriate data, but every once in a while we get the following error either as an informational text at the top of the iview or as stack dump error.
    Error during search occurred - com.sapportals.wcm.WcmException: Index does not exist;index=ourindex (Errorcode 2007)
    Does anybody have any information on a fix for this?

    Hi Aaron
    Indexes are created in ECC or any other SAP for trex search and sometimes indexes may be have to be rebuild, have you checked this particular index shown in the error message 'ourindex'

  • TREX search failure for some pdf documents

    Hi,
    TREX search is not getting correct result for some pdf documents. It's not able read the content of some pdf documents. When we search with file name the search result is correct but we are getting "No document excerpt available" message in search result for this file name.
    Let me know where might be the problem for those pdf docs.
    Thanks

    Hi Tatayya Marni,
    1. Can you tell me whether the pdf documents are opening when you are selecting them?
    2. This error comes mostly when you havent included this .extn file (.pdf in your case) to the portal.
    3. Check whether this extn is their in your portal if not make it inclueded and then try making a new index and one new data source where your pdf is residing. Try for one Test.
    You have to include the file extns in System Confi....UI Interface...
    Hope this will resolve your issue.

  • TREX search in Content Server

    Hey
    I have a problem making TREX search for documents in my content server. I have made some Content Repositories where i want to perform my search.
    What I have done so far, is to make a CM Repository for the Content Repository with Persistence Mode = DB and the Repository ID in Database = The repository i want to use in Content Server.
    Then I have added this CM Repository to a index and restarted the servlet engine. When i search for the documents, I get no hits. I know there is nothing wrong with my TREX, cause i can search on File System Repositories.
    Have i missed anything? The Content Repository is up and running, and i get successsfully on every test.
    Please hit me back!

    Hi,
    Creating an Index
    http://help.sap.com/saphelp_nw2004s/helpdata/en/73/66c090acf611d5993700508b6b8b11/frameset.htm
    Before doing that you should check TREX Server Status:
    System Administration->System Configuration->KM->Index Administration->Related links->TREX Monitor
    If the status is ok, then create the index, assign data source (point your repository), define kind of service (search, search and classification, classification) and define scheduler.
    Then in Index Monitoring you can check status of the index.
    Also, in TREX Monitor you can display Queves and check status of the documents.

  • Sending query to third party portal from TREX Search Engine

    HI Experts,
    we need to implement normal search option in SAP portal.
    when we search any thing from portal ,
    It has to search in EP & KM and also it has to search
    windows sharepoint portal and bring the data back to SAP Portal.
    For this purpose one solution is
    1) implementing  enterpise search,
       but my client dont want to go for enterprise search(federated search).
    2) The other way
    Sending query to third party portal from TREX Search Engine
    In this way what i want is ,
    how TREX can send query to third party portal SEARCH ENGINE
    (in my case share point portal search ENGINE).
    There is no problem to search in EP & KM becuse it is default.
    To search in Micro soft Share point portal,
    TREX should pass the query to share point portal search ENGINE.
    Is there any API TO send a query to third party portal like sharepoint?
    I searched in SDN and Other sites also but i am not getting exactly what I require.
    If any one has ideas or implemented already please guide me.
    My client require searching option like this,
    we need to provide drop down box in SAP Portal with 3 options like
    1) search in Share point portal
    2) search in SAP EP & KM
    3) Search in both the portals
    please provide any code samples in case if you have.
    please help me , its urgent
    Thanks in advance.
    Regards
    Bala

    Hi Bala,
    please check the information on the KM IMS (Index Management Service) in KMC's developer guide. A connection to a 3rd party search is done from KM, then calling TREX and XY in parallel, not serially from TREX.
    Here's a paper describing this for an older KM release:
    https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/5e514b57-0701-0010-3796-deb3636835fa

  • TREX Search issue

    I am using TREX search for equipemnt in R/3 itself. It is working fine in sand box environment but has some issue in quality server.
    It is not filtering data for one maintenance plant. For Ex. - When I give a keyworld and maintenance plant A as parameter it is working fine, giving me filtered results on maintenance plant. But when I give same keyworld and maintenance plant B as parameter it is giving me results from all plants including B also. In second case It should give result for only plant B.
    Can anybody give any idea where could be the problem?
    Thanks in advance.
    Sanjay.

    Hello Sanjay,
    can you give us the exact syntax you´re using to add the filter parameter? Could the name of plant B contain any keyword that triggers another function / causes some confusion in the search request?
    regards, Bastian

  • Ajax framework : how to remove the Trex search field ?

    Hi community,
    I am trying to remove the TRex search field in an ajax framework. As for the "normal" framework I make not visible the tool page, even in the headerless framework, but it is still displaying...
    Has someone ever face this problem ?
    Thanks a lot.

    Hi Fabien
    I am not sure if i got your question currectly
    In general on the Ajax Framework page there is the masthead iview
    On the masthead iview there is a property "Enable Search" that allows you to enable and disable the search box in the page.
    Please try to use it
    There is now search box of the framewrok in headerless window
    the search box is probably part of the application.

  • Go Directly to Career Path 'Results' Page in E-Recruiting (Unreg Search)

    Hi,
    I am working on the E-Recruiting Unregistered Search Page.
    As a default, the Search Criteria page appears as a first page. When the user does the required selection and presses 'Start Search', he is shown the results page with the required record set.
    We are trying to go directly to the end-results page and wish to do away with the search criteria page.
    Can anyone help on this one please!
    What I have studied untill now is that when we reach the search criteria page, the system keeps the stack of all the Controllers that it needs to call in order to display the page. After this it moves that stack to the cookie.
    When the user presses the 'Start Search' button, the event 'Search' is triggered and the stack from the cookie is retrieved. And based on the check, whether the event was triggered or not, the additional Controllers are added to the stack and the results page appears.
    Now my question is; can we trigger this event dynamically? If yes, then how. What needs to be done in order to just pass through the search criteria page as if it does not exist at all...?
    I would highly appreciate if anyone of you could throw some light on this issue...!!
    Thanks & Regards,
    Sanjiv Tyagi

    Well doing this is quite hard.
    I would recommend skipping TREX search at all.
    Make a BSP containing just the result list. Build up your hitlist manually from database, if there is no search, instead using TREX.

    Hi John,
    the performance issue is not the TREX search. In most cases it takes long time to check if the user have at least read permissions to the document listed in the search result list. That's why it takes more time to display 20 hits than 5 hits.
    Using more or less repository services doesn't change ther performance for the search result.
    Using a user with Content Administrator permission must have the best performance because in this case ther document permissions are not checked.
    To improve the performance you can try to use a ACL cache or increase the size of the ACL cache.
    Best Regards
    Frank
