Depending on your time requirment, you can as you have suggested yourself write your own QueryParser. However a simple hack will be to have an "all" field and simple reindex the data in F and G to this "all" field. > little JavaCC expertise.

Well this is definitely not "higher" level than QueryParser :) HTH victor On Thu, 3 Jul 2003 09:41 am, Ali Rouhi wrote: > Hi > 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.
