I have been trying to use grep, but my file is way too big (~300gb). Could
Lucene search through it more efficiently than grep?
Thanks,

Not sure what the business-case for this is and why you cannot use
RegEx for this. But you could consider chopping up the document into
(sub) documents and adding them to the Lucene index. For example, chop
by paragraph or line-break.

Hi,
Can Lucene be used to return all matches of a query (perhaps using regex)
in a single document? If so, is it just as efficient if it was to match
multiple documents? How can that be done?
Thanks

definitely be faster.
There are some other oddities in your results...
- the "consolidated index" shows to be slower 295ms vs 602ms... but
patch 1596 doesn't touch that code path (a single segment index).

I am sorry,
but after applying this patch, the performance on my tests are worse than
those on lucene-2.9-dev trunk.
TEST1: using *filter.getDocIdSet(reader)*;
*Test *results* (Num docs = 2,940,738) using lucene-core-2.9-dev trunk**
1 Original index (12 collections * 6 months = 72 indexes)*
10 matches
