Examples of NexusAnalyzer

org.apache.maven.index.context.NexusAnalyzer
A Nexus specific analyzer. Only difference from Lucene's SimpleAnalyzer is that we use LetterOrDigitTokenizer instead of LowerCaseTokenizer. LetterOrDigitTokenizer does pretty much the same as LowerCaseTokenizer, it normalizes to lower case letter, but it takes letters and numbers too (as opposed to LowerCaseTokenizer) as token chars. @author Eugene Kuleshov @author cstamas
