AJAX Search module can not work on Joomla 3.6.4

It seems that AJAX Search module has not been updated for a long time, the current version can not work on Joomla 3.6.4, could you please update it to make it compatible with latest Joomla core?

Thank you.

This site is on latest Joomla and AJAX Search works just fine...

When I tried to use AJAX Search Module on my website (now upgraded to Joomla 3.6.5), I got nothing shown as search results. Then I press F12 on Chrome browser, I saw following error message:

Failed to load resource: the server responded with a status of 500 (Can't find FULLTEXT index matching the column list SQL=SELECT DISTINCT f.filetitle, c.name AS containername, f.containerid, f.fileversion, f.description AS text, f.filedate AS created, 'File Repository' AS section, CONCAT('index.php?option=com_remository&Itemid=517&func=fileinfo&id=',f.id) AS href, '2' AS browsernav, f.id AS resultid FROM #__downloads_containers AS c INNER JOIN #__downloads_files AS f ON f.containerid = c.id LEFT JOIN #__downloads_text AS t ON t.fileid=f.id WHERE (MATCH (t.filetext) AGAINST ('+mo' IN BOOLEAN MODE) OR MATCH (f.filetitle,f.description,f.smalldesc,f.fileauthor) AGAINST ('+mo' IN BOOLEAN MODE)) AND f.published != 0 ORDER BY f.submitdate DESC)

(there were links among those text messages, but your forum said the link is too long so I deleted them. Links are for com_search component).

What does these error message mean? How to fix this?

Thank you.

Not sure but it can be related to remository search plugin. This site is 3.6.5 and AJAX search works fine, as you can verify.
