Re: ArrayIndexOutOfBoundsException in ToParentBlockJoinQuery

2014-10-14 Thread Mikhail Khludnev 
Hello Fasial,

It's convenient to use wt=csv to verify block layout (make sue that rows=
is high enough). Note, every span of children should be followed by parent.
see
http://blog.griddynamics.com/2013/12/grandchildren-and-siblings-with-block.html
Putting BRAND_s: clause into the {! which= } is absolutely wrong. That
param should contain only parent docs filter which differentiate them from
parents. Any parent level filters should be passed at the top level of
query or like fq=.

 Thanks Erick,

 I am using the 4.10.0 solr. To update any field, I first delete all
 existing documents matching _root_:id before inserting the updated version.
 So, I don't think that's causing the problem.
 Is there a way to validate the sanity of the index, are there any tools
 which can analyze the index and list problems or inconsistencies in the
 index?

 Thanks,
 Faisal

Thanks a lot Mikhail, moving parent filters to fq solved the problem.
Thanks for the wt=csv technique that also was very helpful.

Thanks.

Re: ArrayIndexOutOfBoundsException in ToParentBlockJoinQuery

2014-10-13 Thread Erick Erickson 
There's the CheckIndex tool, but I don't know whether it checks this case.

Is there any way you could check this against 4.10.1? I know there
were a couple of edge cases that were fixed in that release, but have
no idea whether block joins were affected.

But other than that, I'm clueless.
