What happens if a document is deleted while there's a reader open on the
index, and the segments are merged? Maybe I misunderstand what you meant by
this statement, but if the external file is deleted, sin

You can still use TopDocs.totalHits from searchAfter; that will be correct.
Providing "Last" with searchAfter is not really possible; it's also
somewhat strange (does anybody really use that?). Maybe you could
reverse your sort, take page 1, reverse its hits?

Hi,
In my current implementation of Lucene 4.3 where there are millions of indexed
records, I do a regular search() and get the topDocs.totalHits as the count of
results.
As part of this, I store all the results in the session and then let the user
paginate through the results. With this, I am

Mike,
For now I'm using just a SpanQuery over a ~600MB index segment
single-threadedly (one segment - one thread, the complete setup is 30 segments
with the total of 20GB).
I'm trying to use Lucene for the morphologically annotated text corpus (namely,
Russian National Corpus).

Mike, you are right. I used StringField, but id_to_delete has a typo and
thus a mismatch.
Still good to confirm the understanding is correct.
Thanks for your helps.

DirectPostingsFormat holds all postings in RAM, uncompressed, as
simple java arrays. But it's quite RAM heavy...
The hotspots may also be in the queries you are running ... maybe you
can describe more how you're using Lucene?

Hello!
I've tried two approaches: 1) RAMDirectory, 2) MMapDirectory + tmpfs. Both work
the same for me (the same bad:( ).
Thus, I think my problem is not disk access (although I always see getPayload()
in the VisualVM top).
So, maybe the hard part in the postings traversal is decompression?

Boosting query clauses means more "this clause is more important than
that clause" rather than "make the score for this search higher". I
use it for biblio searching when want to search across multiple fields

Your understanding is correct, and after reopen you should see the
document deleted, so I'm not sure offhand why you aren't.
BTW it's w.deleteDocuments not w.removeDocuments.
And you don't need to commit in order to see changes in the reopened

Yes, I think you should have a play. But on an index that is as
realistic as you can make it - there may be variations in performance
of the different queries and filters depending on term frequencies and
loads of other stuff I don't understand. General point being simply
that YMMV.

If you're using Solr you'd be better off asking this on the Solr list:

You might also like to clarify what you want with regard to sentence
vs document. If you want to display the sentences of a matched doc,
surely you just do it: store what you need

I have one requirement where i have to display sentences of valid document
