"As Randy commented earlier, it appears that Solr automatic truncation defaults to "on". If we have a choice, I think it should default to "off" if there is an easy mechanism through which searchers can specify that they want it, such as with a "?" at the end of a word (however Solr does this). As it is, the search results are pretty broad. Randy mentioned doing a search on "optics" and getting optical disks of Shakespeare. I also did a search on "cats" and got tons of manuscripts from the British Library with the catalog number starting with "cat". This truncation seems to go further than users would expect even when indicating automatic truncation - it would be fine to have the search results for "cat" to give you everything that includes "cat" plus anything after: cats, catalog, etc. but it seems to be stemming the original search term as well to lop off part of it and make the search very broad. The existence of the facets seems to negate the relevance ranking that would otherwise put things that match on fields such as physical description, notes (as in these cases) pretty far down the list."
