Improved search

[SmilyOrg]

Is your feature request related to a problem? Please describe.
The current search implementation is not discoverable and has lots of limitations, see #65 (comment). It's not possible to combine search terms or have expressive search queries.

Describe the solution you'd like

• Integrated search help to make it more discoverable, see WIP search-help branch
• GitHub-like expressive search system, tailored for photos. This will likely need several iterations and the details are a bit stuck in my head right now, but hit me up if you're interested!

Describe alternatives you've considered
Not doing it or making it simpler 😅

Is searching across collections a planned feature?
I would love to have a "global" search to go through all collections for tags, eg. tag:work-project/tag:fav, or even finding similar images across collections.

I've not really tested it, but I'm thinking you could already create an "all" collection that contains all the dirs/photos from other collections, then search that.

Of course it would be nice to make that more properly supported, but I haven't thought through how exactly.

An easy way with minimal changes would be to just have a special collection name that acts as an automatic "all" collection.
