Notes:
- the issue has the same Console error as in T382009: Fulltext search is broken on wikidata.beta.wmflabs.org
- the issue is present only for Special:MediaSearch (not Special:Search) and only on commonswiki beta. MediaSearch on commonswiki wmf.20 and on testwiki wmf.21 works fine.
Steps:
- On commonswiki beta go to Special:MediaSearch and enter a simple search term, e.g. cat(https://commons.wikimedia.beta.wmflabs.org/wiki/Special:MediaSearch?type=image&search=cat)
- The message will be displayed - Invalid search Query was not understood. Please make it simpler. The query was logged to improve the search system.
