PhraseQuery artificially enforces that the Terms you add to it are in the same field ... you could easily write a PhraseQuery-ish query that takes Terms from differnet fields, and ensures that they appear "near" eachother in terms of their token sequence -- the context of that comment was searching for instances of words with specific usage (ie: "house" used as a noun) by putting the usage type of each term in a different term in a seperate parallel field, but with identicle token positions.
It seems like this could even be done in the same field if one had a query type that allowed querying for tokens at the same position. Just index "_noun" at the same position as "house" (and make sure there can't be collisions between real terms and markers via escaping, or use \0 instead of _, etc). -Yonik
