Pagination with hits_per_page to limit per page but got error

[mech]

I am trying to limit the pagination using hits_per_page with Kaminari:

Candidate.search("", page: 1, hits_per_page: 5, sort: ["name:asc"])

But was given this error:

MeiliSearch::ApiError: 400 Bad Request - Json deserialize error: unknown field `hitsPerPage`, expected one of `q`, `offset`, `limit`, `attributesToRetrieve`, `attributesToCrop`, `cropLength`, `attributesToHighlight`, `showMatchesPosition`, `filter`, `sort`, `facets`, `highlightPreTag`, `highlightPostTag`, `cropMarker` at line 1 column 21. See https://docs.meilisearch.com/errors#bad_request.

Removing the hits_per_page and I got back the first 20 records of the first page.

I even replace it with limit, but no luck:

# Replacing to limit don't work also
Candidate.search("", page: 1, limit: 5, sort: ["name:asc"])

Is there any special options we are not aware of? Or is pagination not working and need to wait for v0.29

• OS: macOS 12.5
• Meilisearch server version: v0.28.1
• meilisearch-rails version: v0.7.1
• Rails version: v7.0.3.1

Hi @mech I found what happened, I'll provide a fix soon!

[brunoocasali]

@mech I created a branch with the fix, I need to have my PR approved to release a new version.

So while I wait for the approval, you have some options:

• You can reference this branch directly in your Gemfile
• You can change from hits_per_page to hitsPerPage

Thanks for using Meilisearch ❤️

Wow tks, hitsPerPage does work. I will use this temporarily.

[brunoocasali]

It will be released soon as 0.7.2!

I am puzzle, when I do a search, it appear it is querying all 200 records no matter which page I am on.

Doing Candidate.ms_search("", page: 2, hitsPerPage: 3) will result in such SQL:

SELECT * FROM "candidates" WHERE id IN ($1, $2, ...... $200)

Is this normal?

[brunoocasali]

Yes, it is normal because Meilisearch does not provide a way to know the total hits yet.
@curquiza explained this here: #138 (comment)

It is something we plan to improve in the future, in fact, we already have a prototype for this meilisearch/meilisearch#2635 feel free to give your thoughts there :)

Tks for clarification, will play with the new prototype 👍
