Michael McCandless commented on LUCENE-2393:
--------------------------------------------
Patch looks good Tom -- thanks for cutting over to flex. You could in fact use
the bulk read API here; it'd be faster. But performance isn't a big deal here
:)
Maybe you should require a field instead of defaulting to "ocr"?
Why does GetTermInfo.getTermInfo take a String[] fields (it's not used I think)?
Probably we should cutover to BytesRef here too, eg TermInfoWithTotalTF?
Maybe you could share the code between HighFreqTermsWithTF.getTermFreqOrdered &
GetTermInfo.getTermInfo? (They both loop, summing up the .freq() of each doc
to get the total term freq).
Small typo in javadoc thier -> their.

> 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
