Description

Using solr 8.3.0 it seems like required operator isn't functioning properly when default conjunction operator is AND.

Steps to reproduce:

• 20 docs
• all have text field
• 17 have the value A
• 13 have the value B
• 10 have both A and B (the intersection)

•  default operator is set to AND

 

• my query is:

  +A OR B

 

• the result is all 20 docs (as if I searched

  A OR B

  )

 

• when I change my query to be

  {!q.op=OR} +A OR B

  I get my expected result which is "A is required B is optional" (which in this case happened to be all 17 docs that includes the value A, some of them includes the value B but none of the not include A!)
