我四处搜索（双关语），但没找到答案。有没有办法在搜索时排除某些选项？例如，使用 `-@jesselperry` 来排除我发布的帖子，或者使用 `-#contribute:feature` 来排除“feature”分类下的所有结果？

I think it is good idea to add this as a new advanced search feature. I would suggest using additional format for search filters, similar to what it is used in [Github search](https://help.github.com/articles/search-syntax/#filter-qualifiers-based-on-exclusion). It follows advanced filters formats which are also used as an alternative in Discourse advanced search:

- -user:dmacjam
- -category:feature
- -tags:plugins,sso

This has been implemented, for tags at least:

> [@New search operator "not" for tags only](https://meta.discourse.org/t/new-search-operator-not/52087/32):
>
> @tgxworld Do you mean splitting on -tags: instead of -? So for more complex example: tags:eggs+beacon -tags:lunch,sandwiches it would search for posts with eggs and beacon tags, but without lunch and without sandwiches tags? Then, I think it would be a quick change.
