RE #2: You could use query-time boosting to boost the relevance of the
'fulltext' field... I don't have an example of the top of my head but I
think this should be possible... maybe even combining your original query
with a fulltext:{query}^10 (where '10' is the boost value... this is
probably too high! but suffices for demo purposes.)
Another example:
* A "normal" search for Brian Cox:
http://demo.dspace.org/xmlui/discover?scope=%2F&query=Brian+Cox
Note that the first result is a non-text bitstream, so not full text. The
second result is a text bitstream which should be indexed as fulltext.
* A "boosted text" search for Brian Cox:
http://demo.dspace.org/xmlui/discover?scope=%2F&query=Brian+Cox+OR+(fulltext:*+AND+Brian+Cox)^10
Here we see the fulltext item appearing first, because the OR I wrote (which
just combines the original query with a fulltext:* query) is boosted by 10.
^VALUE is standard lucene queryparser syntax, so it's easy to use with Solr
too.
Cheers,
Kim

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
