I'm not entirely clear what you're trying to accomplish, but there's a bunch of options.
You could just index the phrases as normal text, possibly with positionincrementgaps (assuming more than one phrase is possible in a field in a document). Then you could use SpanQuerys to accomplish the "simple" form (choosing suitable increment gaps and suitable distances on your span queries would insure that hits wouldn't span phrases). You could then use regular queries to accomplish the non-simple queries as they're pretty much unaffected by increment gaps. If that's total gibberish, perhaps a more complete example would allow a clearer response.
