get a list of terms sorted by total term frequency
hi,
is there a simple way to get a list of all terms that occur in a field
sorted by their total term frequency within that field?
TermsComponent (http://wiki.apache.org/solr/TermsComponent) "provides
fast field faceting over the whole index", but as counts it gives the
number of documents that each term occurs in (given a field or set of
fields). in place of document counts, i want total term frequency
counts. the ttf function
(http://wiki.apache.org/solr/FunctionQuery#totaltermfreq) provides
this, but only if you know what term to pass to the function.

i see... using the -t flag
it would be cool if TermsComponent had an option to sort by total term
frequency, something like
terms.sort={count|index|ttf}
surely that's a common enough use case

Lucene's misc module has HighFreqTerms tool.
