Mikhail Khludnev updated SOLR-3076:
-----------------------------------
Attachment: bjq-vs-filters-illegal-state.patch
Hello,
The parser itself is not a very big deal. I'm stuck with filtered search for
ToParentBlockJoinQuery. I'm attaching neat test for it.
incepted at
http://lucene.472066.n3.nabble.com/ToParentBlockJoinQuery-vs-filtered-search-td3717911.html
Giving Michael's resolution I amended
o.a.l.s.join.ToParentBlockJoinQuery.BlockJoinWeight.scorer(AtomicReaderContext,
boolean, boolean, Bits):
* children query scorer obtains readerContext.reader.getLiveDocs() - all
documents
* parent filter obtains acceptDocs to instantiate parent DocIdSet.
now it fails TestBlockJoin.testSimpleFilter() line 196 I use parent filter as a
filter for search (it shouldn't influence th result). I've got an exception
java.lang.IllegalStateException: parentFilter must return FixedBitSet; got
org.apache.lucene.search.BitsFilteredDocIdSet@19ccba
at
org.apache.lucene.search.join.ToParentBlockJoinQuery$BlockJoinWeight.scorer(ToParentBlockJoinQuery.java:197)
it's caused by CachingWrapperFilter.getDocIdSet(AtomicReaderContext, Bits) and
BitsFilteredDocIdSet.wrap(DocIdSet, Bits).
(if you don't apply changes to ToParentBlockJoinQuery, assert fails with zero
doc found - parent filter is applied to children query)
it seems to me:
* I did something absolutely wrong or
* I need to manage ToParentBlockJoinQuery work with BitsFilteredDocIdSet - I
guess it might be possible.
