Limit Number of Results being returned #3941

Closed alifazeli closed 3 months ago

Describe your question

I use ElasticPress on a WordPress with a huge number of posts. Due to performance issues, I want a maximum of 1000 results to be returned per search, and the filters in the ElasticPress filter widget will also select and display the list of items within these 1000 results. In this way, users can see and filter only the first 1000 results separated from all results related to the query without affecting the score of results.

I changed the value of 'ep_max_results_window' to 1000 but there was no change in the number of results and always if the number of results is high it returns the maximum number of 10000 posts.

Is there a way to reduce the maximum of returned result ?

Code of Conduct

Hi @alifazeli,

ep_max_results_window only works if the posts_per_page parameter is set to -1 https://github.com/10up/ElasticPress/blob/develop/includes/classes/Indexable/Post/Post.php#L1591. If it has any other value, that value will be used as the maximum limit.

Additionally, ensure that you are using the filter correctly. Your code should be look like this:

    add_filter( 'ep_max_results_window', function() {
        return 1000;
    } );

Regards, Burhan

Hi @burhandodhy

Thanks a lot. I'm not sure, maybe I'm wrong and ep_max_results_window has nothing to do with my problem. I don't want to limit the number of results per page and I can do that with WordPress widgets. I want to limit the total number of results returned in each search. If ep_max_results_window is related to the same issue though, where can I change the posts_per_page value?
