All Implemented Interfaces:

com.atlassian.bonnie.ILuceneConnection

public class DidYouMeanLuceneConnection
extends com.atlassian.bonnie.LuceneConnection

A subclass of LuceneConnection that allows us to set the index directory off the location of the Confluence index and allows us to use a DelayCloseIndexSearcher in place of the normal IndexSearcher returned by LuceneConnection.getSearcher().

The index searcher managed by this connection also uses a customized Similarity class. The purpose of which is to negate the idf for n-gram matches (as we consider all n-gram matches to be equal).
