Hi, I have the same reflexion actually. If you add an another field for exact search, and the end cannot type a search like : "convertible" +house Because in this sample, for 'convertible' the user want an exact search but not for 'house'.
And I don't want to develop an new parser for query. I think, the solution is to add something in the stemmer analyser to store exact word too, and a parser that don't stem expression in quote.
