Yonik Seeley updated SOLR-10939:
--------------------------------
Attachment: SOLR-10939.patch
Here's a patch that refactors and reuses the graph points collector for join.
I also made some changes to the join test:
1) if Points are selected, then docValues must be enabled (an exception is
thrown otherwise)
2) removed testing joins across incompatible fields (for example matching an
int field to a text field won't result in any matches)
> JoinQParser gives incorrect results with numeric PointsFields

> If you try to use the {{\{!join\}}} QParser with numeric points fields, you
> will get silently incorrect results.
> The underlying root cause seems to be that JoinQParser's JoinQuery assumes
> every field it's dealing with has indexed terms. (AFAICT it won't even work
> with {{indexed="false" docValues="true"}} Trie fields????)
