Mark,
Does it help if you rewrite your query using +/- syntax ("required",
"prohibited"), or nothing for "should"? Because that's what happens under the
hood (terms are required, prohibited, or should occur).

> Here is my query:
> (virt* AND "machine fingerprinting") OR (virt* AND encryption) OR (virt* AND
> anonymous) OR (virt* AND analytic*) AND owned:true
>
> It can be broken down to:
> (A) OR (B) OR (C) OR (D) AND E
>
> A, B, C and D are themselves AND boolean clauses.
>
> The E clause at the end is not behaving the way I would expect. No matter
> how I order the A,B,C and D clauses, it always returns the equivalent of
> ((D) AND E).
>
> When I add additional parentheses it behaves the way I expect. Like:
> ((A) OR (B) OR (C) OR (D)) AND E
> or
> (A) OR (B) OR (C) OR ((D) AND E)
>
> Can anyone explain why it behaves the way it does without the parentheses?
> Is there something I am missing in the way it processes boolean clauses?
