Michael McCandless commented on LUCENE-1479:
--------------------------------------------
Ahh the last minute "trivial" code fix... gets you every time ;)
With the new patch, a document missing a date is assigned the current Date,
right? Can we instead leave it as unset (null)? (Does DocData allow a null
Date)?
Can you add a test case exposing the bug & showing the fix?
> TrecDocMaker skips over documents when "Date" is missing from documents

> TrecDocMaker skips over Trec documents if they do not have a "Date" line.
> When such a document is encountered, the code may skip over several documents
> until the next tag that is searched for is found.
> The result is, instead of reading ~25M documents from the GOV2 collection,
> the code reads only ~23M (don't remember the actual numbers).
> The fix adds a terminatingTag to read() such that the code looks for prefix,
> but only until terminatingTag is found. Appropriate changes were made in
> getNextDocData().
> Patch to follow
