A better stemmer does sound attractive.  As far as whether this justifies the switch, I have two main concerns to weigh it against:  frequency of updates and long-term support.  I know we're waiting on Solr 1.4 for at least one feature (spellchecker reindex on optimize), and it would be unfortunate if using a different build significantly delayed our ability to take advantage of the new Solr version or future fixes/enhancements.  It could also be a problem in the future if Solr moves on and the LucidImagination build dies -- we could end up becoming dependent on a feature set that is no longer part of active Solr development.  I'm not sure how likely it is that either of these things will become problems -- I'm new to Solr and unfamiliar with LucidImagination -- but I think they're considerations worth keeping in mind when making the choice.

Subject: [VuFind-Tech] Upgrade Solr to LucidImagination Solr release

 

Hi Folks - I was poking around at LucidImagination's SolrWorks website and was thinking about switching Solr in the VuFInd source to use their custom build.  It has some nice enhancements that I would like to take advantage of - mainly the KStemmer since the PorterStemmer is ridiculously advantageous in it's stemming.

Anyone have any thoughts or comments on replacing Solr from the community build to the LucidImagination build?

Thanks
Andrew
