Could you provide some examples of the data in the untokenized fields? At first glance there really is no need to use a PhraseQuery for the untokenized fields - a simple term query would suffice for that case.
How should your clauses be grouped? Like: (<searchTerm1> AND < searchTerm2>) OR (< searchTerm3> AND < searchTerm4>) Or: <searchTerm1> AND (< searchTerm2> OR < searchTerm3>) AND < searchTerm4> You can create a BooleanQuery with other BooleanQueries as clauses to group them as desired.
