Endeca | Configure Stemming in CAS based application

Stemming : Stemming broadens search results to include root words and variants of root words.

For example, search results for the word truck will include the derivation trucks, while a search for trucks will also include its word root truck.

Steps to Configure Stemming : You can configure stemming manually in stemming.xml file. This file is located in <Endeca_App_Directory>/config/mdex directory. You can manually update this file. If stemming.xml does not contain an entry for a language, stemming is not enabled for that language and the default analysis is applied to that language.

In stemming.xml, the entry for a language is contained in a separate <STEMMING> element. Each subelement in the <STEMMING> element begins with STEM_language-code, where language-code identifies the language; for example, STEM_DE for German.

The subelements specify the following :

• Whether stemming is to be performed on that language.
• Whether a static wordforms file is to be used.
• Whether compound matching is to be performed.
  

For example, the following entry, for American English, specifies that stemming is to be performed using a static wordforms file, and that compound matching is not to be performed.

<STEMMING>

<STEM_EN_US ENABLE="TRUE"
USE_COMPOUND_MATCHING="FALSE"
USE_STATIC_WORDFORMS="TRUE"/>
</STEMMING>

Endeca | Configuring features of a CAS-based application through XML files

If you are using CAS to process your data, rather than Forge, there is a subset of application features that you must configure manually in the instance configuration XML files for an application. You cannot use Oracle Oracle Commerce Workbench or Developer Studio to configure these particular features.

The following table provides a mapping between application features and the corresponding XML file where you configure each feature. The instance configuration files are stored in <app dir>\<app name>\config\mdex.
