Minor clarification re the exslt license: that applies to the external exslt implementations, which you only need if your xsl engine doesn't support exslt natively. Since Xalan does, at least mostly, it's all already there in Solr.
I agree that more flexible date-time parsing of input to Solr is also desirable.

The exslt stuff looks good, thanks! I'll have to try it out. That's only one direction though, still want parsing of unix timestamp-like formats into the indexer on doc adds and updates. Just FYi the license for the exslt stuff seems OK w/ the APL: http:// lists.fourthought.com/pipermail/exslt-manage/2004-June/000603.html So if it works out we might want to put the date/time xsl stuff in the solr distribution in lieu of shipping with a XSL 2.0 processor. >> >> Those are interesting ideas and it probably would not be difficult to >> create a patch if you were interested, but I'm curious: What about >> XSL makes what seems to me an elementary string-processing task so >> difficult? >> > > Well, XSL 1.0 (which is the one that "comes for free" with Solr/java) > doesn't handle dates and times at all.
