you definitely can do it because the only thing that is in the docsets is a uri starting with https?:// or file:/// .

It seems there are some docsets already doing that[1]. Creating your own docsets is dead easy. just a simple sqlite3 file with a single table.

You can find an example I hacked myself here[2] (very hackish).

It's basically creating a table:

    create table searchIndex(id INTEGER PRIMARY KEY, name TEXT, type TEXT, path TEXT); 
    CREATE UNIQUE INDEX anchr  ON searchIndex (name, type, path);

And filling it with data:

    insert into searchIndex(name,type,path) VALUES ('foo','function','https://example.com')
