<P>
An Analyzer builds TokenStreams, which analyze text. It thus represents a policy for extracting index terms from text. <p> Typical implementations first build a Tokenizer, which breaks the stream of characters from the Reader into raw Tokens. One or more TokenFilters may then be applied to the output of the Tokenizer. <p> WARNING: You must override one of the methods defined by this class in your subclass or the Analyzer will enter an infinite loop.
