Right way to add items to a ResultSet

$search_api_fields_helper = \Drupal::service('search_api.fields_helper'); $index = $query->getIndex(); $user_datasource = $query->getIndex()->getDatasource('entity:user'); $items = $results->getResultItems(); // Store all the user added to the results $user_ids_added = []; /** @var \Drupal\search_api\Item\ItemInterface $item */ foreach ($items as $item) { $language = $item->getLanguage(); $itemId = $item->getId(); $values = []; $fieldUid = $item->getField('uid_1'); if ($fieldUid) { $values = $fieldUid->getValues(); } if (isset($values[0]) && !empty($values[0])) { $uid = $values[0]; $user = User::load($uid); if ($user instanceof UserInterface) { if (!$user->hasRole('my_role')) { continue; } if (in_array($uid, $user_ids_added)) { continue; } $id = 'entity:user/' . $uid . ':' . $language; $new_item = $search_api_fields_helper->createItem($index, $id , $user_datasource); $results->addResultItem($new_item); $user_ids_added[$uid] = $uid; } } }

Thank you for the fantastic module! I realize this issue is closed, but there is surprisingly little to be found on this, so I thought I would post my question in case others stumble across this post.

When adding items to a ResultSet in this way, find find two issues. For me, I'm combining content nodes and commerce product entities in my search results. When using a particular search term, there are 130 matches. Since my page size is set to 48 items per page, these 130 are broken into 3 pages. I've tried using both the SearchApiSolrEvents::POST_EXTRACT_RESULTS and search_api.processing_results events and I have the same results with each.

Problem #1: The items are added to each page of the results. Meaning, if I add an additional 3 items to the ResultSet in the EvenSubscriber, the first page has 51 items, the second page has 51 items, and the third page has 37 items. The last 3 items of each page are my additions. How might I add these 3 items to the initial ResultSet of 130 items so they are only shown on one page?

Problem #2: The items are added to the end of the list of items for any page. I've used the $new_item->setScore(51); to manually set the score higher than all other items, but my additions remain at the bottom of the list. How do I modify the relevancy for these items so they move to the top of the ResultSet?

To all who may happen upon my previous comment, I've received a response on Drupal Slack from one of the project maintainers pointing me to the code from the Visitors Voice project here:

https://www.drupal.org/project/visitorsvoice →

This is a D7 project, but apparently contains the result modification logic I am looking for. Additionally, a final comment:

"Basically, though, you’ll always need to index extra fields if you want to modify the search results in a seamless way (i.e., without messing up paging, sorting, facet counts, etc.)."

I will post my results once I'm able to successfully implement the addition of items to my ResultSet.
