Hoss Man updated SOLR-5125:
---------------------------
Attachment: SOLR-5125.patch
ok, so MoreLikeThisComponent.getMoreLikeThese was already pulling out
MoreLikeThisParams.DOC_COUNT to use as rows, and already has the ResponeBuilder
-- so in this page I just eliminated the "flags" argument from it's signature
and pulled it from rb.getFieldFlags() instead.
So i think this should work -- but my quick attempts at verifying it with a
test didn't work out...
* the only MLT Component test i can find is DistributedMLTComponentTest
* DistributedMLTComponentTest is currently {{@Ignored}}
* when i un-ignored DistributedMLTComponentTest it passed for me with and w/o
the patch
* when i tried to change the test to use "mlt.count=100" everywhere, the test
also passed both with and w/o the patch
...so either there is some other variable at play here that i'm missing, or
this tests is useless -- i suspect maybe the later, it's not 100% clear to me
what the test is doing, but it seems to only be verifying that the control
client matches the distrib client -- but never verifies that anything useful is
returned from either.
