Detailed Description

Basic classifier to identify queries like:

• simple words: foo bar
• simple phrase: "foo bar"
• simple words + simple phrase; foo "bar baz"
• complex: any queries that use a keyword, or any non trivial features
• bogus queries: queries where a bogus pattern have been identified at parse time
