Hi I need to perform a search for an expression in multiple fields "as if" they were one field. This is best illustrated by a simple example.
Find expression (X AND Y) in fields (F, G). I want this to translate to: ((X in F) OR (X in G)) AND ((Y in F) OR (Y in G)) In other words I want the query to return true *not only* if ((X AND Y) in F) OR ((X AND Y) in G) (1) but *also* the following should give me a true value ((X in F) AND (Y in G)) OR ((X in G) AND (Y in F)) (2) I believe that "MultiFieldQueryParser" just gives me (1) and leaves out the "cross terms" in(2).(If you want a practical example of why one would want to do such a search I would be glad to provide one). Of course I could construct the combination of (1) and (2) manually, but the problem is that I want the "general solution" with a general expression being searched for in multiple fields in the manner of the above example. I have a feeling that this sort of a thing is best done by writing a custom QueryParser.jj. We use Lucene in production code and have great java expertise, but little JavaCC expertise. Suggestions for solving the problem at a higher level than the QueryParser are of course also very welcome. Many Thanks Ali __________________________________ Do you Yahoo!? SBC Yahoo!
