Problem with sorting by swedish chars

[klingberg]

Describe your question

Since I updated to version 5.0.2 my custom posts (in wp api call) are no longer sorted correctly. Å is treated as A, Ä is treated as A and Ö is treated as O. When I use version 4.5.2 swedish chars are sorted correctly.

I tried to fiddle with this solution https://github.com/10up/ElasticPress/issues/977 but I get an error when I try to sync. My guess is that some of the array keys has changed names since this solution was posted so I wonder if you could help me with an updated workaround?

I now see in the status report that I have an error:

        }
      }
    ]
  },
  "status": 400
}

This is what causes the error:

add_filter('rest_contact_query', function($args, $request) {
    $args['orderby'] = 'meta_value';
    $args['meta_key'] = 'last_name';

    return $args;
}, 10, 2 );

If I remove the filter above I get no errors and the posts are ordered by post title but still in incorrect order with "å" being treated as "a" etc. I should also mention that I use Polylang to separate Swedish and English results.

Hi @klingberg, thanks. Although that helps, I meant the ElasticPress Status Report that you can find by going to your WordPress dashboard, then ElasticPress > Status Report.

For the error you are seeing, did you include last_name as an indexable meta field in your Weighting Dashboard? If not, you'll need to do it, and resync.

Adding the meta field "last_name" in the Weighting Dashboard cleared the error but the posts are still sorted in an incorrect order (åäö still treated as aao).

Thanks, @klingberg, that all looks good. I'll need you to do something else now.

Do you mind installing our debugging plugins, performing a search that returns the wrong results, opening the ElasticPress panel in Query Monitor, clicking on "Download Requests Info" and sharing it with us? Thanks

[klingberg]

Hi!

I have the debugging plugin installed but is it possible to get the debugging information when I fetch the data through an ajax api call? Sorry I did not make this very clear in my description.

[felipeelia]

Hi @klingberg, it will not, but you can go to ElasticPress -> Query Log, and enable it to log AJAX requests there. If you do that, run a search, and come back, it should have the queries that went through ElasticPress in an AJAX context.

Hi!

I think I have found the difference between version 4.5.2 and 5.0.2. The "sort" setting in 5.0.2 seems to sort on a slugified version of the meta field. Here are parts of the query logs:

Hi @klingberg,

Can you add the snippet below to your codebase (more info here on how to do it), run a full sync (checking that "Delete all data..." checkbox?), and let me know if it works?

/**
 * Remove `'asciifolding'` normalizer from ElasticPress.
 *
 * @param array $mapping The post mapping
 * @return array
 */
function ep_custom_remove_asciifolding( $mapping ) {
    $mapping['settings']['analysis']['normalizer']['lowerasciinormalizer']['filter'] = [ 'lowercase' ];
    return $mapping;
}
add_filter( 'ep_post_mapping', 'ep_custom_remove_asciifolding' );

Thanks!

Sorry for the late reply! The last solutions seems to fix the problem. I also had to add the meta field in the "Search Fields & Weighting" panel. Thank you so much and take care!!
