public function Highlight::postprocessSearchResults in Search API 8

Postprocess search results before they are returned by the query.

If a processor is used for both pre- and post-processing a search query, the same object will be used for both calls (so preserving some data or state locally is possible).

Parameters

\Drupal\search_api\Query\ResultSetInterface $results: The search results.

Overrides ProcessorPluginBase::postprocessSearchResults

File

src/Plugin/search_api/processor/Highlight.php, line 238

Class

Highlight

Adds a highlighted excerpt to results and highlights returned fields.

Namespace

Drupal\search_api\Plugin\search_api\processor

Code

public function postprocessSearchResults(ResultSetInterface $results) {
  $query = $results

    ->getKeywords($query))) {
