[CODE4LIB] adding FastVectorHighlighter to solr

[Bess Sadler]

One of the feature requests we get pretty often with Blacklight is search term highlighting. The main reason we don't have it yet is because it's a performance drag. We have attempted to add it a couple of times, but it kills performance so much for large collections or large text fields that we had to remove it again.

I just had an interesting chat with Erik Hatcher, and he pointed me at this: http://www.lucidimagination.com/search/document/a4deefd915f706d4/highlighting_performance

https://issues.apache.org/jira/browse/SOLR-1268



Cheers,
Bess

It seems Lucene 2.9 has a faster highlighting solution available now, FastVectorHighlighter. However, it hasn't yet worked its way into solr. If you are one of the people who would like to see search term highlighting (or, maybe just faster search term highlighting) in blacklight, vufind, Fac-Back-OPAC, helios, or any of the many other library apps that use solr, you might want to go vote for the jira issue at: You'll need to register for a jira account at the apache software foundation, but it only takes a minute.
