Subject Re: Classic QueryParser, StandardQueryParser, Quotes

A StrField field is not tokenized. So, do not expect "a b" to match "a a b". Lucene will generate
a single term from "a b", and a single term from "a a b", so obviously, they do not match.

If you want to match these two texts, change the field to TextField and use the appropriate
analysis (standard standard analyser is a good start). Run your analysis again.
