Related Posts not work

[rstrah]

Describe your question

I have function:

function ep_get_related_posts($post_id = null, $related_post_count = 5)
{
    if (class_exists('\ElasticPress\Features')) {
        $related_posts = \ElasticPress\Features::factory()->get_registered_feature('related_posts')->find_related($post_id, $related_post_count);

        if ($related_posts) {
            echo '<h2>Похожие новости:</h2>';
            echo '<ul>';
            foreach ($related_posts as $related_post) {
                echo '<li><a href="' . get_permalink($related_post->ID) . '">' . $related_post->post_title . '</a></li>';
            }
            echo '</ul>';
        } else {
            echo 'No related posts found.';
        }
    } else {
        echo 'ElasticPress is not available.';
    }
}

I get "No related posts found"

I call it like this (I'm sure the $id being passed is not empty) ep_get_related_posts($id, $related_post_count = 5)

Through the block in Gutenberg I get the same thing(If you use your block).

@rstrah, ep_get_related_posts($id, $related_post_count = 5), how $id is being created?

Also, using the debugging add-on, if you visit the page where the "No related posts found" message is displayed, you should be able to debug the query being sent to ElasticPress. When you get that, feel free to share it here if you want.

@felipeelia Hi.

<div class="main-content" id="<?php echo $post->ID; ?>">
<?php render_news_whole_post($post->ID,NULL,true); ?>
<?php ep_get_related_posts($post->ID, $related_post_count = 5); ?>

Like that )

i have problem

[felipeelia]

@rstrah the query is going through, but not finding anything related. This is the Elasticsearch query:

{
    "from": 0,
    "size": 5,
    "post_filter": {
        "bool": {

                            "post"
                        ]
                    }
                },
                {
                    "terms": {

            },
            "fields": [
                "post_title",
                "post_content",
                "terms.post_tag.name"
            ],
            "min_term_freq": 1,
            "max_query_terms": 12,

        }
    },
    "sort": [
        {
            "post_date": {
                "order": "desc"
            }
        }
    ]
}

You will need to make sure your content is properly indexed, and that you have content in the "post" post_type with similar title, content, and/or tags of the post with ID 1236992.

If you need to use different fields, you'll need to use the ep_related_posts_fields filter, with something like this:

add_filter(
    'ep_related_posts_fields',
    function( $fields ) {
        $fields = array_merge(
            $fields,
            [ 'post_content_filtered', 'terms.category.name' ]
        );
        return $fields;
    }
);

(more options are available in this gist.)
