Name Description
QueryAutoStopWordAnalyzer An Analyzer used primarily at query time to wrap another analyzer and provide a layer of protection which prevents very common words from being passed into queries.

For very large indexes the cost of reading TermDocs for a very common word can be high. This analyzer was created after experience with a 38 million doc index which had a term in around 50% of docs and was causing TermQueries for this term to take 2 seconds.
