Hi Mike,
I am sorry for the delay of this reply.
Regarding your issue with the toolbar search being redirect you to Joomla search, this is because you've a menu item's alias 'search' conflict with EasySocial 'search' view. When EasySocial generate the sef link for the search page, it used the view name as part of the sef, e.g. /search?q=xxxx
To fix your issue, I've renamed your Joomla search menu item the alias to 'searchall' and now the toolbar search result link is pointing to correct page
There are multiple users that meet the "jami" search, yet only 1 is returned.
The EasySocial toolbar search actually utilised smart search where it doesn't support loose search. If you enter your search term with 'jamie', you will be able to find 11 users. This is because all these users has the 'jamie' in part of the name. However, only one user has the name with 'jami', hence you are getting 1 result returned from the search. For your information, this behaviour is actually same like smart search module. The only different is that, smart search module 'suggest' the search term to you before it actually perform the search
Hope this help and have a nice day!
