Add parsing raw query for modifiers

[sarayourfriend]

Problem

Currently from the frontend if you want to search for galah images that are cc0 you'd need to execute a search for galah first, then use the UI to add the cc0 filter.

For power-users this adds an unnecessary extra step.

Description

We could add a feature like most search engines have and allow the query itself to supply extra parameters of the search. For example, we could add a (not well-named) license option that could work like this:

galah license:cc0,pdm

This would automatically select the cc0 and pdm filters. Similarly:

galah providers:flickr

galah file-type:jpeg,png provider:flickr,smithsonian license:cc0,pdm

And so on, would also work.

I think it'd be best to implement this on the API side rather than directly in the frontend so that this feature would be automatically available to any frontend that hooks up to the API without having to reimplement the parsing.

Additional context

This feature would require an implementation plan if we decide to do it.

Implementation

• 🙋 I would be interested in implementing this feature.

Cool idea!

Great idea, I have some thoughts on how this could be implemented but it needs work in two places (so maybe we could move it to the WordPress/openverse repo).

API:
The API backend already has an implementation to use filters (like license) passed as query params, so without much effort, it can be tweaked to populate and extract those filters from the search term q field.

Frontend:

The frontend might also need some work to parse queries containing advanced filters and populate the UI based on those. For example, when searching for galah license:cc0,pdm, the search box must be populated to galah and the checkboxes for cc0 and pdm in the license filters must be checked.

@dhruvkb That's such a good point, this is basically just moving the query params into the raw query, the format is almost exactly the same if you replace = with : to match how most search engines do it. Let's do move this to the openverse repo like you suggested 👍
