Mike Sokolov updated LUCENE-1889: --------------------------------- Attachment: LUCENE-1889.patch This patch adds support for highlighting MultiTermQuery in FastVectorHighlighter via Query.rewrite(). I left one FIXME (should that be nocommit?) that should be fairly easy to resolve: we currently rewrite() the same MTQ query twice in some circumstances - if it's in a phrase I think. I'd be happy to sort that out if y'all decide to commit this. > FastVectorHighlighter: support for additional queries > ----------------------------------------------------- > > Key: LUCENE-1889 > URL: https://issues.apache.org/jira/browse/LUCENE-1889 > Project: Lucene - Java > Issue Type: Wish > Components: modules/highlighter > Reporter: Robert Muir > Priority: Minor > Attachments: LUCENE-1889.patch, LUCENE-1889.patch > > > I am using fastvectorhighlighter for some strange languages and it is working > well! > One thing i noticed immediately is that many query types are not highlighted > (multitermquery, multiphrasequery, etc) > Here is one thing Michael M posted in the original ticket: > {quote} > I think a nice [eventual] model would be if we could simply re-run the > scorer on the single document (using InstantiatedIndex maybe, or > simply some sort of wrapper on the term vectors which are already a > mini-inverted-index for a single doc), but extend the scorer API to > tell us the exact term occurrences that participated in a match (which > I don't think is exposed today). > {quote} > Due to strange requirements I am using something similar to this (but > specialized to our case). > I am doing strange things like forcing multitermqueries to rewrite into > boolean queries so they will be highlighted, > and flattening multiphrasequeries into boolean or'ed phrasequeries. > I do not think these things would be 'fast', but i had a few ideas that might > help: > * looking at contrib/highlighter, you can support FilteredQuery in flatten() > by calling getQuery() right? > * maybe as a last resort, try Query.extractTerms() ? -- This message is automatically generated by JIRA.
