C# 클래스 Lucene.Net.Analysis.Compound.DictionaryCompoundWordTokenFilter

A TokenFilter that decomposes compound words found in many Germanic languages.

"Donaudampfschiff" becomes Donau, dampf, schiff so that you can find "Donaudampfschiff" even when you only enter "schiff". It uses a brute-force algorithm to achieve this.

You must specify the required LuceneVersion compatibility when creating CompoundWordTokenFilterBase:

  • As of 3.1, CompoundWordTokenFilterBase correctly handles Unicode 4.0 supplementary characters in strings and char arrays provided as compound word dictionaries.
