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=“[//cdck-file-uploads-global.s3.dualstack.us-west-2.amazonaws.com/meta/original/3X/9/d/9d9e5d0ba84892a132ca1505ed87d1e7deb222b4.png](https://cdck-file-uploads-global.s3.dualstack.us-west-2.amazonaws.com/meta/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? ---

鉴于这个话题被移到了 #Contribute > Feature 分类，我猜这是暂时不行吧 🙂 ---

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](https://meta.discourse.org/t/multiple-tags-search-query-takes-too-long-big-forum/56023/3) 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. ---

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? ---

[https://github.com/discourse/discourse/pull/4896](https://github.com/discourse/discourse/pull/4896) 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` ---
