How can I implement InstantSearch, Typesense-Minibar or Docsearch with pg_search?

[stephane-klein]

Hello,

I'm investigating the option of using pg_search instead of Meilesearch or Typesense.

I understand how to configure a BM25 index.

Now I'm wondering how I'm going to implement an HTTP API in order to use InstantSearch, typesense-minibar, autocomplete or docsearch with pg_search.

I've done some searching on GitHub, so far, I haven't found anything.

Should I split the requested string and pass it as a parameter to TermSet?

Do you have any resources or advice for me?

Best regards,
Stéphane

Hey @stephane-klein, it should be sufficient to just format your user's query into the string passed to search:

SELECT * FROM my_index.search('some_field:"<user-query>"');

We also support nearly all of Tantivy's query structures, so you might find that things like PhraseQuery and PhrasePrefixQuery might be useful to you for things like autocomplete.
