C# Class org.apache.lucene.analysis.standard.ClassicAnalyzer

Filters ClassicTokenizer with ClassicFilter, {@link LowerCaseFilter} and StopFilter, using a list of English stop words.

You must specify the required Version compatibility when creating ClassicAnalyzer:

As of 3.1, StopFilter correctly handles Unicode 4.0 supplementary characters in stopwords

As of 2.9, StopFilter preserves position increments

As of 2.4, Tokens incorrectly identified as acronyms are corrected (see LUCENE-1068)

ClassicAnalyzer was named StandardAnalyzer in Lucene versions prior to 3.1. As of 3.1, StandardAnalyzer implements Unicode text segmentation, as specified by UAX#29.
