Description:

LocationService::moveSubtree can result in such a query being executed:

SELECT parent, text_md5 FROM `ezurlalias_ml` WHERE
    (is_alias = ?) AND
    (is_original = ?) AND
    (action_type = ?)
    AND (link = ?)

Running:

EXPLAIN SELECT parent, text_md5 FROM `ezurlalias_ml` WHERE
    (is_alias = 0) AND
    (is_original = 0) AND
    (action_type = 'eznode')
    AND (link = 67);

shows that link column is not part of the index and number of checked rows is unnecessarily high.
