Search API Solr Pro

search_api_solr_pro

Module extension to prevent the entities being loaded from solr results in views by a query setting.

Motivation:

The well know module search_api_solr (https://www.drupal.org/project/search_api_solr) force the entities to beign loaded from the solr results in views, ignoring if the user only want to display specific fields that are already indexed in solr. In that case we can improve the performance of view generation avoiding the load of the entities.

Install module

Repo: Download from here!

1. Clone the repo into the drupal module folder
2. Activate the module in the drupal admin section extend Alt text

3. Set the solr server backend to "Solr Pro" Alt text

4. Move the index to the new server and re index them
5. Go to the view
6. Open the advance query setting dialog Alt text

7. Check the option "Skip entity load" Alt text

8. Specified the indexed fields you want to use in the view (If the field is set as excluded for render then it will not be available in the view)
Note: In the twig file for the view you will find the fields in the row object, for example:

<li class="alpha-section__list-item">
  {% if title %}
    <h3>{{ title }}</h3>
  {% endif %}
  <ul class="alpha-section__sublist">
    {% for row in rows %}
      {%
      set row_classes = [
      default_row_class ? 'views-row',
      ]
      %}
      <li>
        {% set result_row = row.content['#row']|obj_to_arr %}
        {% set name = result_row['entity:authors/person_name'][0].getText() %}
        {% set url = result_row['search_api_id']|replace({':und': ''}) %}
        {{ link(name, url) }}
      </li>
    {% endfor %}
  </ul>
</li>
