COMMENT ON TEXT SEARCH CONFIGURATION golang IS
'TEXT SEARCH CONFIGURATION golang is a custom search configuration used when creating tsvector for search.
The url_path token type is removed, so that "github.com/foo/bar@v1.2.3" is indexed only as the full URL string,
and not also"/foo/bar@v1.2.3".
The ASCII token types are set to a "simple_english" mapping, so that "plural" words like Postgres and NATS
will be indexed without stemming.
This idea came from the "Morphological and Exact Search" section here:
https://asp437.github.io/posts/flexible-fts.html.';
