I'm trying to find a way to retrieve from a Solr query the total number of
hits for a query across all documents.
I'm using an edismax query handler which searches across several fields
(specified in the schema.xml).
I have tried:
/solr/my_core/keyword?q=knights of arabia&fl=ttf:totaltermfreq(html,'knights
of arabia')
but the totaltermfreq function only works on individual terms
I have also tried
/solr/my_core/keyword?q=knights of arabia&facet=true&facet.query={!edismiax}
knights of arabia
which retrieves the total number of documents found with the search terms
within (same as numFound)
What I want is the total number of times the search terms appear in all
documents. For a standard disjunctive query like this it would total all
occurrences of 'knights', 'of' and 'arabia'. For a query like q="knights of
arabia", it would only count all occurrences of the entire phrase, and for
q=knights AND of AND arabia the number would be the total number of times
each term appears across all documents (but results would be fewer than
q=knights of arabia as documents must have all three of these terms in them
by the nature of the query).
I hope this makes sense and that there is some way I might be able to do
this that I am missing? I would also (begrudgingly) be happy if the answer
is that due to the way searching works, this is not possible and Solr/Lucene
will not easily be modified to do this.
