That's pretty much the way lucene currently works - you don't know what fields match a query. If the query is simple, looping over the returned stored fields is probably your best bet. There are a couple other tricks you could use (although they are not necessarily better): 1) with grouping by query (a trunk feature) you can essentially return both queries with one request: q=*:*&group=true&group.query=A_NAMES:smith&group.query=B_NAMES:smith and optionally add a "group.query=A_NAMES:smith OR B_NAMES:smith" if you need the combined list 2) use pseudo-fields (also trunk) in conjunction with the termfreq function (the number of times a term appears in a field). This obviously only works with term queries. fl=*,count1:termfreq(A_NAMES,'smith'),count2:termfreq(B_NAMES,'smith') You can use parameter substitution to pull out the actual term and simplify the query: fl=*,count1:termfreq(A_NAMES,$term),count2:termfreq(B_NAMES,$term)&term=smith -Yonik http://www.lucidimagination.com
