The Search Service analyzer to be used when converting from the application database text terms to Index terms. The contents of this column should denote one of the predefined analyzer names provided by the Generic Search Server (see the list below) or a fully qualified Java classname of a class that implements the abstract class org.apache.lucene.analysis.Analyzer. This may be either a standard Lucene analyzer or a third-party or custom implementation. Note that the class must be available on the Generic Search Server classpath if it is not a standard Lucene analyzer.
For a list of the analyzers supplied with GSS and a more in-depth discussion of how to choose an analyzer, see Analyzers in Depth.
