If I wanna add tags to my metadata, I have to write ,tags: t/test". To use later the tag #t/test in a note.If I then wanna add the tag to a others file metadata, I not just can write #t/test to getting recommendations, because then metadata is not processing them. So I have to write #t/test and after that, remove the # to make it to → t/test.
The graphView is not marking files with tags: #t/test. So for making them visible in graphView I have to use the form t/test.
And the searching function is also just detecting t/test and not #t/test.
It sounds like you are editing your properties in Source Mode? If so, to use # in the tags property, you need to quote the tag:
---
tags:
- "#example"
---
In Live Preview, the properties editor does this automatically if you type a # with your tag. (The properties editor is the default interface to properties in Live Preview. If you don’t see it, there is a setting to make it appear.)
If you want Obsidian to recognize tags in property fields other than tags, comment on this feature request:
