Hi Tim
yes i'm using Xapian since it was available in ePrints.

uh.. i have always been thinking that you knew that ePrints search engine is its weakest point, but that it was ok for you.

i did already report suggestions and comments about the ePrints searching experience in last years

what i really need to achieve is a google like search within thousands of texts.
and since Solr it's possible!
i have been using Solr integrated with other platforms (PHP CMS), and it's not difficult to implement advanced facetting, synonymous, "you intended..", auto complete, similar, result grouping and highlighting in summary listing..
since Solr is doing all the mechanics, its client has just to inject the document with relevant meta data.
it already comes with interpreters for most document types.

this is something that DSpace has begun to do (with 3.0), and many platforms are abandoning their custom searches, integrating good connections with Solr (or ElasticSearch)

PS: recently i could live with ePrints because i did inject all it's data into VuFind 2.0 (which uses Solr as base search engine)
but it's a mess to explain to the users the 2 platforms!

so we have begun to experiment with alternatives!

ciao
