language support?

I think current language is the way to go, but maybe give the admin an option to expose a language selection.

For my purposed I adjusted the SQL to check a condition for the language column in the node table against the current language

global $language;
$language->language;

i'd put up a patch but i don't know how because i don't git it.

fuzzysearch.module,v 1.16.2.37

I altered that file on line 891-914 to be this:

global $language;

  // Main query
  $sql = "SELECT n.nid, MAX(n.moderate) AS moderate, MAX(n.uid) AS uid, MAX(n.type) AS type, MAX(n.status) AS status, SUM(subpercent) AS percent, SUM(subscore) AS score
          FROM (SELECT DISTINCT word_id, nn.nid, SUM(completeness) AS subpercent, SUM(score) AS subscore
            FROM {fuzzysearch_index} s
            LEFT JOIN {node} nn ON (nn.nid = s.nid)
            WHERE (($clause) AND nn.language='".$language->language."')
            GROUP BY word_id, nn.nid HAVING SUM(completeness) >= %d) AS q
          LEFT JOIN {node} n on n.nid = q.nid
          WHERE n.status = 1
          AND n.type NOT IN ($placeholders)
          GROUP BY n.nid ORDER BY percent DESC, score DESC";

  // Count query
  $sql_count = "SELECT COUNT(DISTINCT(n.nid))
               FROM (SELECT nn.type, nn.uid, nn.moderate, nn.nid, CEILING(SUM(completeness)) AS completeness, SUM(score) AS score
                 FROM {fuzzysearch_index} AS s
                 LEFT JOIN {node} nn on s.nid = nn.nid
                 WHERE $clause AND nn.language='".$language->language."'
                 GROUP BY word_id, s.nid, nn.type, nn.uid, nn.moderate, nn.nid
                 HAVING SUM(completeness) >= %d) AS q
               LEFT JOIN {node} n on n.nid = q.nid
               WHERE n.status = 1
               AND n.type NOT IN ($placeholders)";
