Results Page "Sort By" Relevance to be built out

[karencolbron]

Results page "sort by Relevance" is not active.

Is this still to be built out, based on the metadata fields we display in the UI?

Relevancy is a very complex topic and is discussed at a high level here:
http://wiki.apache.org/solr/SolrRelevancyCookbook

Basic relevancy does appear to be working accurately in HydraDAM, however, users may have differing understandings of what constitutes relevant results. There do not appear to be enough, or diverse enough, objects in the repo to do significant relevancy tuning at this time.

Our recommendation would be to populate the repository with a significant number of items first (1,000-10,000) to produce a large enough search sample size to meaningfully test and tune relevancy.

This level of tuning is far outside the scope of the initial HydraDAM grand and contract.
