Erick Erickson commented on SOLR-7249:
--------------------------------------
Please raise usage issues on the user's list before raising a JIRA to confirm
that what you're seeing is really a code issue. If so _then_ raise a JIRA.
In this case, attach &debug=query to the output and you'll see that the parsed
output is very much different than what you expect. It is not surprising at all
that the output from a standard query is different than that from edismax as
edismax is spreading the terms across a bunch of fields _as clauses_.

> Solr engine misses null-values in "OR null" part for eDisMax parser
> For example, I have following query:
> ((*:* AND -area:[* TO *]) OR area:[100 TO 300]) AND objectId:40105451
> full query path visible in Solr Admin panel is
> select?q=((*%3A*+AND+-area%3A%5B*+TO+*%5D)+OR+area%3A%5B100+TO+300%5D)+AND+objectId%3A40105451&wt=json&indent=true
> so, it should return record if area between 100 and 300 or area not declared.
> it works ok for default parser, but when I set "edismax" checkbox checked in
> Solr admin panel - it returns nothing ("area" for objectId=40105451 is null).
> Request path is following
> select?q=((*%3A*+AND+-area%3A%5B*+TO+*%5D)+OR+area%3A%5B100+TO+300%5D)+AND+objectId%3A40105451&wt=json&indent=true&defType=edismax&stopwords=true&lowercaseOperators=true
> However, when I move query from "q" field to "q.alt" field - it works ok,
> query is
> select?wt=json&indent=true&defType=edismax&q.alt=((*%3A*+AND+-area%3A%5B*+TO+*%5D)+OR+area%3A%5B100+TO+300%5D)+AND+objectId%3A40105451&stopwords=true&lowercaseOperators=true
