Dear all,

It is my first time that I am trying to use Elasticsearch and I would apologize for any inconvenient question.

I am trying to use elasticsearch in wordpress for two main reasons, first performance and second higher quality "related posts" feature.

I installed elasticsearch server, I installed elasticpress wordpress plugin, I synchronized(indexed) database with the help of plugin. search is working very well but not related posts.

Related posts is give me only last posted articles not related posts:

I call this plugin function ep\_find\_related(post\_id, return) which is suppose to return me related posts but instead of that it returns latest posts which are not related to post\_id. Below is the plugin function with formated\_args function:

function ep\_related\_posts\_formatted\_args( $formatted\_args, $args ) {  
if ( ! empty( $args['more\_like'] ) ) {  
$formatted\_args['query'] = array(  
'more\_like\_this' =\> array(  
'ids' =\> is\_array( $args['more\_like'] ) ? $args['more\_like'] : array( $args['more\_like'] ),  
'fields' =\> apply\_filters( 'ep\_related\_posts\_fields', array( 'post\_title', 'post\_content', 'terms.post\_tag.name' ) ),  
'min\_term\_freq' =\> 1,  
'max\_query\_terms' =\> 12,  
'min\_doc\_freq' =\> 1,  
)  
);  
}

```
return $formatted_args;

```

}

/\*\*

- Search Elasticsearch for related content
- 
- @param int $post\_id
- @param int $return
- @since 2.1
- @return array|bool  
\*/  
function ep\_find\_related( $post\_id, $return = 5 ) {  
$args = array(  
'more\_like' =\> $post\_id,  
'posts\_per\_page' =\> $return,  
'ep\_integrate' =\> true,  
);

Please let me know what I am doing wrong

Thank you for taking your time to help me.
