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
Roman

  • 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 not working from TRM

    Dear experts,
    We have a strange problem in our implementation.We have configured TREX 7.0 with eRecruiting 603.The TREX is without SES.
    If i go to succession planning & do the search against a succession plan(requistion) by clicking cnadidate search, i get search results & i can assign them to the plan.
    If i go to Talent Relationship Management & try to do the search,it gives me an error"An internal error occured.Please try again later".
    If i go to SLG1 & check the logs, i can see the following:
    "Proficiency scale could not be read
    Message no. HRRCF0001127
    Diagnosis
    The proficiency scale could not be created. Possible reasons:
    Missing Customizing

    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
    Please make the entries accordingly..

  • 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.

  • File name to be considered while Trex Search in CV04N,

    Dear Sap Gurus,
    I know TREX can search and list the documents using any Word or Characters inside the original file, but i have a requirement to search the document by there File Names,i tried giving File names in CV04N Trex search window, but it is not giving any results for me,
    how can i make the trex search consider the file names also while searching in CV04N,
    In SAP DMS is there a standard search functionality to search the documents by there File name?
    Awaiting response
    Thanks and regards
    Kumar

    Thanks for your response,
    i know we can search the documents through Classification or description details using CV04N, but
    while searching any document the user wishes to fill up the details only at one field ie... the Trex search window in the CV04N screen, and he will not be interested in filling  the values at the classification TAB and the description Tabs,
    we need a single point of search through Trex search Window in CV04N, ie... when this Trex search field is filled appropriately,( like the classification value, Long text value,) 
    this values should search the documents with this Classification or Long text values in DIR and display the results,
    i could not succeed in getting the trex search working with this values, is there any thing missing from DMS config????
    FYI,
    we have Portal Document search through DMS through DMS Connector, and in this Trex Search we could find the DMS documents using the file Names as well, but strangely  the same thing is not possible through CV04N trex Search,
    Thanks and regards

  • 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 for Archive Link OAAD or OAWD Documents,

    HI Sap Gurus,
    Can Trex Search in the originals of documents which are stored by OAAD or OAWD Transactions,
    if so how to activate the Trex Original document Search for Documents stored through OAAD or OAWD,
    Thanks and regards
    J Sari,

    Dear Athol,
    We are using SAP Content server to store our Documents from GOS and also the same Content server is used  for maintaining our Documents through DMS also,
    so as a standard, Trex cannot search documents maintained in content server by GOS methord and it can only search those documents which are maintained by DMS CV01N method,
    pls suggest how to proceed for the development to allow Trex to search all the documents in Content server, how big is the development, is there any SAP suggested solution to be followed,
    Thanks and Regards

  • TREX search KM BI Repository

    TREx 7.1
    Portal 7.0
    I have created and been using a KM BI Repository. This repository contains txt documents that are currently being accessed thru a KM Document IVIEW. I have recently implmented  TREX 7.1 and I am having trouble finding anything in my repository using the search UI.
    I have added indexes and taxonomies that point to the data source /bi_documents.
    The search UI is available but finds nothing.
    The TREX search can find Portal Documents.
    I have also added to the Index Management Service the  "Repository Manager" that is for my BI Repository.
    Component Monitor is good and all green
    TREX Monitor good.
    My searchs still return nothing from my KM BI Repository.
    I have researched and followed numerous documentation on repositories.
    Any help or configuration document on KM BI Repositories would be appreciated.
    Thank you,

  • TREX Search on attachments in CRM 7.0

    Hi ,
    Is the TREX search on the attachments to Service orders,Activities.etc  in CRM7.0 a standard functionality? Do we have to do any enhancements for enabling the TREX search on attachments to Service orders etc..in CRM 7.0

    Hi,
    I guess this is not only in CRM 7.0, this should be possible in very old CRM releases already.
    The extra step is in
    spro->CRM->Enterprise Intelligence->Software Agent Framework->Name and Configure Knowledge Base
    the flag: Compile URL Instead of Text
    should be turned on.

  • 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.
