Description

filter queries are not properly filtering results when using a join query in solr4

To replicate, use the attached patch file which contains a test method that will fail (but should pass).

OR

run the solr example:

cd solr
ant example
java -jar start.jar
cd exampledocs
java -jar post.jar *.xml

Then try a few of the sample queries on the wiki page http://wiki.apache.org/solr/Join. In particular, this is illustrates the issue:

Find all manufacturer docs named "belkin", then join them against (product) docs and filter that list to only products with a price less than 12 dollars
http://localhost:8983/solr/select?q=

{!join+from=id+to=manu_id_s}

compName_s:Belkin&fq=price:%5B%2A+TO+12%5D

When you run that query, you will get two results, one with a price of 19.95 and another with a price of 11.5 Because of the filter query, I'm only expecting to see one result - the one with a price of 11.99.

I was able to track this down to a change in revision #1188624 (http://svn.apache.org/viewvc?view=revision&revision=1188624 : LUCENE-1536: Filters can now be applied down-low, if their DocIdSet implements a new bits() method, returning all documents in a random access way). Prior to that revision (i.e. 1188613 and before) the test method will pass and the example will work as expected.

• is broken by: LUCENE-1536 if a filter can support random access API, we should use it
