public static function SarniaSolrService::phrase in Sarnia 7

Used instead of SearchApiSolrConnection::phrase, since the original method's quoting makes it impossible to use wildcards or other quoting.

This phrase escaping allows wildcards, AND and OR, and double quotes.

1 call to SarniaSolrService::phrase()

SarniaSolrService::formatFilterValue in ./service.inc

Override SearchApiSolrService::formatFilterValue() because it relies on SearchApiSolrConnection::phrase().

  $value = preg_replace('/[:(){}\\[\\]]/', '\\\\\\0', $value);

  // Escape search operators or wildcards appearing at the beginning of the value.
  $value = preg_replace('/^(AND|OR|NOT|\\*|[+-])/', '\\\\\\0', $value);

  // Escape unmatched double quotes.
  if (substr_count($value, '"') % 2 != 0) {
