I think there is a bug when searching multiple tags. Here is the strange result I got on my Discourse:
Based on the search, there should be 8 results. But it displays 9. The 2nd result is correct, but not the 1st one.
I wonder if the issue with the hyphen, since the mistaken result also contains the a tag that includes some of search terms ( -reports). The issue does not appear when searching for just committee-reports.
I might be reading this wrong, but wouldn’t this simply imply the topic only needs to contain one of the provided tags?
Or am I reading that incorrectly?
I guess it’s late 
Thanks for pointing out what should have been obvious.
Is there a way to search for two tags with AND instead of OR?
Based on this topic being moved to the Contribute > Feature category. I take it that’s a no – for now 
FWIW, I was just doing a multiple tag search to share a list of posts with someone and expected the search would return the intersection (AND) instead of the union (OR). So, found this post and adding a +1 
for the option to AND multiple tags in a search.
@burke, you can actually do it but it isn’t performant (depending on the number of tags and topics you have)
Multiple Tags search query takes too long ? - big forum - #3
You would specify the tag item multiple times, such as tag:pr-welcome tag:foobar
Hi,
Outreachy aspirant here I have successfully installed and run Discourse locally on my machine based on the instructions provided in the Beginners’ development guidelines. I am going through the codebase currently and was trying to get started on a beginner level issue. Is this a good place to start?
Thanks.
I am afraid this is a bit involved, I would pick something a bit more straight forward. PM me with a list of 5 or so features/bugs you find interesting and I will help guide you to the best place to start.
Thanks for pointing out to this helpful workaround @cpradio!
Thanks for the guidance, I am now looking for issues that I am able to understand/find interesting.
Also, there is a lock icon many of the issues. Does that imply they are not open to all contributors?
Closed topics are topics we are done with, they are completed.

With this pull request now it is possible to do logical AND search by multiple tags and the performance is the same for any number of tags. Example search: tag:pr-welcome+foobar
