Hi,

There is random sort and it used to work on Apache solr. After switch to Elasticsearch it’s no longer working, I don’t see error message so no idea how to debug this!

Can you please recheck?

Thank you.

It could be due to https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-function-score-query.html#function-random:

It was possible to set a seed without setting a field, but this has been deprecated as this requires loading fielddata on the _id field which consumes a lot of memory.

It will be checked and eventually fixed on WPSOLR 23.6

Switched from Solr to Elasticsearch and the function just stop working so kind of unexpected! I’m looking forward to the update.

Thank you.

WPSOLR 23.6 is ready.

Hi,

The random sort returns the same result as I tested on 23.6.

Randomness is across sessions: different visitors will see different results. But a visitor will see the same results.

Please try with a new session, like with another browser or in incognito mode.

Hi,

I tested in incognito mode and the result is the same. Seem results are cached and I have no idea how to control it.

Can the random function actually be more random?

Thank you.

You can activate the Query monitor add-on, and check if the Elasticsearch random query yields a different seed with different sessions.

Strangely, I cannot active the extension, it say “Feature-limited version, click to activate”!

Please deactivate your license, and reactivate it.

But a visitor will see the same results.

I just notice this in your previous reply! If so, it’s not really random anymore. Can the seed expire after a certain time so the sort will be random again?

Thanks.

We use the same randomness for Apache Solr and Elasticsearch, generated from wp_get_session_token().

It would explain why the sort result is the same when I test, unless a user logout and login again! Would it be better to consider another option such as expired by time?

Thanks.

We only provide this session-based random feature.

Hi,

For this issue, is there a hooks and filters available to modify the Elasticsearch query, so that I can random generate the seed? Example:

add_filter('wpsolr_elasticsearch_query_args', 'add_random_seed_to_query');

function add_random_seed_to_query($query_args) {
  $random_seed = rand(); 

  // Assuming 'functions' exists in your query, adjust the path as needed
  $query_args['body']['query']['function_score']['functions'][0]['random_score']['seed'] = $random_seed;

  return $query_args;
}
