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
