Description

Hi,

We found a case which Streaming in Solr is returning us no results, when it should return us results.

When the query parameter ("q") in streaming expression consist from only "NOT" (or "-") condition, Solr will not give us any results.

But if we are adding to it also "positive" condition it will work as expected.

In "normal" world, as more conditions we will add to the query, as less results we should get back

 

You can see that in the pictures we attached here.

 

Please let us know what you think and when do you think this issue will be fixed?

Thanks,

Nuriel
