My intent was to find this question How do I re-write those class defined in primefaces.css? to see if it's useful enough to vote as a duplicate or to include as a "see also" link in a new answer.
So I searched using the keyword user:me [primefaces][css]. However, it unexpectedly returned 775 results. It seems that the tags are not searched using the AND condition. Without the "user:me" as in [primefaces][css] it returns 67 results. I tried to fix the search query to be user:me +[primefaces] +[css], but no cigar. It still shows all the 775 results.
Replacing "user:me" with "inheritance" as in inheritance [primefaces][css] yielded exactly 1 result, exactly the answer I was looking for (currently, it's 2 results ;) ).
So it seems that the tags are incorrectly treated as an OR condition when used in combination with "user:me". This seems a nasty bug to me. Can we please fix it?
