I’m retired and not working on Solr all the time, but there are two things I didn’t finish that should be picked up. I’m not going to do these, I’ve got plenty of retirement stuff to do.
The first is SOLR-629, probably the oldest open feature request and a good first project for someone. This adds support for fuzzy search to the edismax query parser. The external impact is tiny, the qf config just says “title~” instead of “title”. The most recent patch is for 4.x. It doesn’t apply 100% to the current code (more like 50%), but it should be fairly easy to figure out the needed mods. This should be a nice project for a first-time contributor, because it is localized to the edismax parse. That is spread out a bit, but not too bad. Besides, who gets to work on a three-digit Jira issue? Two notes: 1. You’ll get the urge to rewrite the whole damned edismax config parser with a real parser generator. Resist that and just make the change. 2. It isn’t possible to have a higher boost for an exact match and a lower boost for a fuzzy match because it only handles one config spec per field name. And it doesn’t throw an error for the second time, either. It really should handle “title^4 title~^2”. The workaround is to make a copy of the title field. Maybe that should be a separate Jira issue? wunder Walter Underwood wun...@wunderwood.org http://observer.wunderwood.org/ (my blog)
