Class CropTerm

  • All Implemented Interfaces:
    TermPipeline
    public final class CropTerm
extends java.lang.Object
implements TermPipeline
    Reduces the size of terms passing through the term pipeline to the maximum allowed size for this indexing run. The crop term pipeline class has been provided as some term pipeline implementators (eg SnowballGermanStemmer) may actually lengthen words that did previously fit in the indexing.
