我认为在搜索多个标签时出现了一个错误。以下是我在我的 Discourse 上得到的奇怪结果：
img src=“//assets-meta-cdck-prod-meta.s3.dualstack.us-west-1.amazonaws.com/original/3X/9/d/9d9e5d0ba84892a132ca1505ed87d1e7deb222b4.png” width=“690” height="428"
根据搜索结果，应该有 8 条结果。但实际上显示了 9 条。第二个结果是正确的，但第一个结果却不正确。
我怀疑这个问题与连字符有关，因为错误的结果中也包含一个包含部分搜索词的 a 标签（-reports）。当只搜索 committee-reports 时，这个问题并没有出现。
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 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
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
