We have a simple domain where 

FirstName_s:"Bob"

returns 40 documents, and

-Department_t:"Ninjas"

returns all of the documents (we don’t have a ninja department).

We expected the query

(FirstName_s:"Bob") OR (-Department_t:"Ninjas")

to return all documents, however it only returned the original 40 documents.

We have experimented with a couple of different orderings, tried using ‘NOT’ instead of ‘-‘ all to no avail.

Is this expected behavior?
Perhaps more importantly, how do we get the behavior we expect?

    I stumbled upon https://issues.apache.org/jira/browse/SOLR-2209 so maybe parentheses are causing error. Does this work ?

    FirstName_s:"Bob" OR -Department_t:"Ninjas"

    Does rewritting the query in a way, that it won’t contain OR (using De_Morgan’s law) helping ?

    -(-FirstName_s:"Bob" AND Department_t:"Ninjas")
