How to disable Stemming for specific languages

Updated

The Stemming can be set under the specific Language settings in AutonomyIDOLServer.cfg.

  1. Stop DocuShare.

  2. Make a current backup of \IDOLServer\IDOL\AutonomyIDOLServer.cfg.

    Where is replaced with the installation directory for DocuShare. The default installation path is C:\Xerox\Docushare. Depending on your installation environment the path may vary.

  3. Open AutonomyIDOLServer.cfg in an advanced ascii editor such as textpad.

    Warning: Do not use the standard Notepad application, because it can corrupt the file.

  4. Search for the language you would like to change the setting for. Example [Russian].

    In the example below the Russian entry is the one modified, search for the language you wish to modify and make appropriate changes based off the examples provided below.

  5. Add the following entry to that section

    Stemming=false

    Note: Stemming is enabled by default. If the parameter doesn’t exist in the AutonomyIDOLServer.cfg file, it is stemming.

    Example of an updated entry (see text in red):

    [russian]

    Encodings=CYRILLIC:russianCYRILLIC,CYRILLIC_ISO:russianCYRILLIC_ISO,CYRILLIC_KOI8:russianCYRILLIC_KOI8,UTF8:russianUTF8

    Stoplist=russian.koi8.dat

    IndexNumbers=1

    TangibleCharacters=@&-_

    HyphenChars=NONE

    AugmentSeparators=!;.

    Stemming=false

  6. Save the file.

  7. Start DocuShare.

    Note: A dsindex index_all is required to change the previously uploaded files.
