| 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.'; |
