Hello Mark: I apologize for not responding earlier, more urgent stuff took over. I really appreciate your help with this. Since my first message was somewhat terse, let me explain again.
My index includes both "regular" fields (stored, indexed, tokenized) and "search-only" fields used for searching only (unstored, indexed, tokenized). In particular, I have one such field called "metadata" that's the accumulation of all metadata about the document (title, authors, date, etc.). Using this field, I can easily query "all metadata" without searching the document text (that's a separate field). It has no meaning other than making this kind of query possible. Say I query "+metadata:apple +banana". I would like to have the term "apple" highlighted in all metadata fields; if Fiona Apple authored a document, her lastname should be highlighted in the "author" field, but not in the document text. >From what I've experienced, when I pass NULL as fieldname to the QueryTermExtractor, "apple" gets highlighted everywhere, both in any metadata AND the document text. When I pass "author" as fieldname, it doesn't highlight that field at all -- because the query was actually for "metadata" not "author". It's not correct in either case, and I'm not sure what to do. Thanks again for your help, --Renaud -----Original Message----- From: markharw00d [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 13, 2007 3:24 PM To: java-user@lucene.apache.org Subject: Re: More Precise Highlighting Not sure I fully understand the problem. The query is effectively "allContent:someTitleText" and you want to highlight the string "someTitleText" in the title field? If you pass null as a fieldname to the QueryTermExtractor it will use all term values, regardless of field, as string to highlight. If you pass a fieldname it will only select highlight term values for that field. If you want, you can use QueryTermExtractor to extract just the "allContent" field values and pass a TokenStream for the "title" field to the highlighter and it would highlight the appropriate values in the title. Do any of these options work? Renaud Waldura wrote: > The old highlighter code used to highlight found terms in any field > (too broad).
