Subject RE: TO Mike McCandless : ToParentBlockJoinQuery inconsistent return
Date Thu, 15 Mar 2012 15:40:06 GMT
Thanks for your two responses.

Best regards,



-> Ok now I have seen the mention of that on  ToParentBlockJoinQuery class java doc....

->This java doc specify : "At search time you provide a Filter
* identifying the parents, however this Filter must provide

* an {@link FixedBitSet} per sub-reader."
                How to insure/test that a built filter provide a FixedBitSet per sub-reader
?  QueryWrapperFilter does respect this need ?

Best regards,

Objet : TO Mike McCandless : ToParentBlockJoinQuery inconsistent return


Bravo for your work on lucene,

A comment :

ToParentBlockJoinQuery return bad children (Children of previous adjacent block)
This happens if parent is the first of the list of document block indexed.
Add the parent at the end of the documents list (as in TestBlockJoin TestCase) solve this

This is a bug or at least a important void in documentation.

Thanks and best regards.
