Class LuceneQueryTokenizer

java.lang.Object
  com.atlassian.confluence.search.contentnames.lucene.LuceneQueryTokenizer

All Implemented Interfaces:

QueryTokenizer

public class LuceneQueryTokenizer
extends Object
implements QueryTokenizer

The purpose of this class is to wrap the tokens emitted from lucene analysis inside our own QueryTokens so that we can tag some additional meaning. Although we could have modified the 'type' property of lucene tokens, we would have had to tinker with all the analyzers for each of the languages we have, which is not feasible.
