Term frequency cache functions.

Code

function facetapi_luceneapi_terms_count(Zend_Search_Lucene_Proxy $index, array $docs, array $terms) {
  $freqs = array();

  // Reading from a termFreqs cache table is MUCH more efficient than
  // calculating them on the fly for every search.
  foreach ($terms as $term) {
    $freqs += facetapi_luceneapi_termfreqs_get('luceneapi_node', $term);
  }

  // NOTE: This is surprisingly efficient.
  return count(array_intersect_key($docs, $freqs));
