Is there any way to set the limit to zero?

[wolfogre]

Thanks for the amazing meilisearch project!

I encountered a problem while using it. I'm wondering if I missed anything.

I just want to get the total number of the search, no need to return any result to speed up. But zero limit will be reset to the default limit, and magic numbers like -1 are not allowed.

I encountered this issue in the Gitea project: go-gitea/gitea#29990, go-gitea/gitea@f886a75

Currently, I have to set it to 1, then clear the result before returning. It works, but I wonder if there's a better way to do it, since it seems Elasticsearch works well with zero limit.

Hi @wolfogre , thanks for the feedback! You didn't miss anything, the limit parameter only accepts integers > 0 currently. I will move this discussion to the feature requests repo.

To clarify, this looks like a limitation of the go SDK, specifically.

A raw curl call to Meilisearch returns the expected:

❯ curl http://localhost:7700/indexes/test4/search -H 'Content-Type: application/json' --data-binary '{"sort": ["Info.ReviewNb:desc"], "limit": 0}'
{"hits":[],"query":"","processingTimeMs":0,"limit":0,"offset":0,"estimatedTotalHits":7}%

The behavior of the Go SDK was introduced by this commit

This bit of code was added to meilisearch/meilisearch-go#4 because previously not passing a limit to the Go SDK would result in the limit being 0.

It appears to be a limit of the Go language that uninitialized values are 0, but I'm not well versed enough in Go to know if there is a better solution.

I would recommend opening an issue against the Go SDK.
