Document search operators better

[shish]

Numeric Score's docs say "you can vote +1 or -1", but there is no mention of all the advanced search stuff that's implemented in:

https://github.com/shish/shimmie2/blob/master/ext/numeric_score/main.php#L201

It would be great to scan all the extensions which implement onSearchTermParse and document all the extra search operators that they supply

Contributing a bit:

With a quick search, these are the extensions that implement this function:

• relatationships (sic)(Post Relationships)
• tag_categories (Tag Categories)
• rating (Image Ratings)
• favorites
• numeric_score (Image Scores (Numeric))
• index (Image List)
• notes ([Beta] Notes)
• user (User Management)
• comment (Image Comments)
• artists ([Beta] Artists System)
• pools (Pools System)

The scan idea seems neat. If we could use it to auto-generate something like Danbooru's tag/search cheatsheet, it would probably be extremely useful for any user wanting to know how the tag/search system works.

Bump. Can I search images larger than N height? Or search by exact resolution?

[shish]

Yup, those things are documented under /help, eg https://shimmie.shishnet.org/help/search
