Hey there,

I am really sorry for the delay of this reply as it is a weekend for us here.

I've tested in my locally, it seems like the system will automatic update that full name from the search engine if user updated their full name.

Perhaps you can update your correct backend login access so I can better have a check?

But those changes are long ago, and still, is there any way to refresh that? and that only the last one comes out nothing more

I've help you removed all the Easysocial - user indexed data from your site backend > component > smart search , then reindex it again, can you try search this keyword 'Ross' or 'Dominatrix' on your site frontend and see how it goes?

It shouldn't show the old user name on the search result now.

Excellent, how can I do it? is updated in the whole database is done individually, since I have several similar cases. thanks for your help

You can do so under the Smart Search at the back end of your Joomla site, http://take.ms/0l5mH
