this brings me to the frequency-based faceting ..
for lack of better term. I am trying to figure out a way to present
the index based on frequency i.e. if i could find a way to do reverse
example :
By Author (15)
- abc (8)
- xyz (7)
By Country ..
- ..
- ..
Keyword XX or Phrase YYY
- Author (15)
- Country (25)
So in the case above the keyword is dynamic and its based on a
frequency
i.e top 100 keywords or phrase beside the stop words etc.. This is
what I
am labeling as "dynamic frequency based faceting" like the example URL
above..
Solr supports facet queries. In your example, Solr could be asked
for a count of all documents (matching other constraints perhaps too,
of course) that have an Author field... that would be
&facet.query=Author:[* TO *], or the opposite, all documents that do
not have an Author field with &facet.query=-Author:[* TO *].
Give saved searches a try in Flare for an example, type each of those
expressions as unique constraints and save them. You'll see what I
mean then, I think. Also, look at the individual facet pages (the
"browse" links by each facet) and see the last entry that shows "---
NO VALUE ---". Is this getting warmer to what you're after?
Maybe I don't know enough maybe its possible to do with solr today.
I have
a feeling that one must extend request handler.. but I haven't
looked into
it yet.
Let me know if the above information doesn't do what you're after,
but I think we got the use-case you're after covered.
I am trying out the flare as plugin I will get back to you with
feedback. That
was very fast converting it to flare plugin.
again, it's a hack at this point. much more work is needed to make
it easily configurable, and to put the templates into the plugin too
(and make them overridable/extensible too).
