Add ability to use Obsidian's search operator

[SeanMcLoughlin]

Obsidian has many search operators listed here. You can do things like query tags or other metadata in your notes. However, it looks like this plugin simply searches the filesystem for note names and not any other metadata.

I would like to be able to query my vault the same way I can in Obsidian using these search operators. That includes using logical operators like this issue mentions.
