Hi,
I'm attempting to use ToChildBlockJoinQuery in Lucene 4.8.1 by following Mike
McCandless' blog post:
http://blog.mikemccandless.com/2012/01/searching-relational-content-with.html
I have a set of child documents which are named works and a set of parent
documents which are named persons tha
ric "Empty" DocIdSet. Which leads to the exception
from ToChildBlockJoinQuery.
The summary is, make sure that your source query only hits documents that
were actually added using 'addDocuments()'. Since it looks like you're
extracting your block relationships from the exis
ument. A child can't be its own parent.
BlockJoin is a very powerful feature, but what it's really doing is
modelling relationships using an index that doesn't know what a
relationship is. The relationships are determined by a combination of the
order that you indexed the block,

Why do you say not to use G1GC? We are using Java 7 & G1GC with Lucene 4.8.1
in production. Thanks.

In fact, the problems with G1GC can sometimes lead to index corruption, and are
hard to reproduce. So better don't use...

And, I assume, it also applies to your custom app.

G1GC with the 64-bit JVM given that it has better performance on large heaps

I am sick of people asking "but isnt it fine on the latest version"
and so on. It is not.

Hi Clive,
We essentially do what you're suggesting, namely we create a single index
searcher (as well as the directory reader it uses) on each partition that is
shared amongst all threads. We also perform various index operations
(searching, browsing terms etc.) for a while to "warm up" Lucene
Hi Stan,
I played around with LIRE a couple years ago. I don't know exactly how it
works, but it doesn't just use Lucene from what I remember, it has its own
classes built around Lucene to perform the image search. There used to be a
PDF of a paper on the site, but I couldn't find a link when
Hi Adrien and Will,
Thanks for your responses. I work with Selva and he's busy right now with
other things, so I'll add some more context to his question in an attempt to
improve clarity.
The merge in question is part of our batch indexing workflow wherein we index
new content for a given par
compared to 4.x?
This sounds robust. Is the index batch creation workflow a separate process?
Distributed shared filesystems?

Hi Scott,
I don't know your reasons for splitting your index up, but assuming you want to
do that and then merge the search results back together I think you could
re-unify the term document frequencies across all your indexes and then extend
IndexSearcher and override termStatistics and collec
We use Kryo to pass query objects between hosts:
https://github.com/EsotericSoftware/kryo
We initially had some trouble with it creating dynamic classes and running out
of PermGen space but we got around that using an ObjectPool:

Here's an archive link from this mailing list regarding serializing queries, I
guess this would work for Automaton objects as well.

Hope it helps.
