the ranking criteria for “OR” operator seems to be counterintuitive.
If I seach:
I get results with both “foo” and “bar”. Nice.
If I search:
foo OR bar
I get results with either “foo” or “bar”, nice. BUT I would expect to get first results with both “foo” AND “bar”, they should have higher ranking. This is a normal ranking strategy for search engine.
Can I set some parameter to obtain such behavior?
Thanks a lot
