Tom Burton-West updated LUCENE-2393:
------------------------------------
Attachment: LUCENE-2393.patch
New patch includes a (pre-flex ) version of HighFreqTerms that finds the top N
terms with the highest docFreq and looks up the total term frequency and
outputs the list of terms sorted by highest term frequency (which approximates
the largest entries in the *prx files). I'm not sure how to combine the
GetTermInfo program, with either version of HighFreqTerms in a way that leads
to sane command line arguments and argument processing. I suppose that
HighFreqTerms could have a flag that turns on or off the inclusion of total
term frequency.

> This is a command line utility that takes a field name, term, and index
> directory and outputs the document frequency for the term and the total
> number of occurrences of the term in the index (i.e. the sum of the tf of the
> term for each document). It is useful for estimating the size of the term's
> entry in the *prx files and consequent Disk I/O demands
