Description
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.
Use the various "addStopWords" methods in this class to automate the identification and addition of
stop words found in an already existing index.
