Note to linux users: You will need the following packages (or their equivalents) to compile successfully: `erlang-dev erlang-parsetools erlang-os-mon erlang-xmerl erlang-tools`
The docs are _not_ static content like you would typically see for documentation. They are all stored in a database, because they can all be full-text searched using postgres. Eventually it would make sense to serve the individual doc pages from a CDN or something like that. The interesting pages in that regard is the `Docs` page. We do quite a bit of work to make sure that we are only loading the html that will be served for the exact document we are seeing.
The magic of search is done via `AshHq.Docs.Extensions.Search`, which modifies resources to make them full text searchable using postgres, amongst other things. See `lib/ash_hq/docs/extensions/search/transformers/add_search_structure.ex` for more.
There is also a usage of `Ash.Flow` for searching, which can be found in `lib/ash_hq/docs/search/search.ex`. It is actually a bit un-ideal, as the better thing to do would be to use a postgres UNION. There are ways to do that with Ash by extracting the resource queries and then making a union, but it was much easier to just put a search action in a flow. Eventually, Ash will support unions.
