Search Plugin look for WHOLE words only

Hello,

So I don't know if it's an issue or Flexicontent wanted that works like that.
But so !
Let's use an example :
I have an article (A) with that content : "My brother"

If Flexicontent Search plugin is disabled and Joomla Search plugin is enabled :
If I look for "brothe" => (A) is found.
If I look for "brother" => (A) is found.

If Flexicontent Search plugin is enabled and Joomla Search plugin is disabled :
If I look for "brothe" => (A) is NOT found.
If I look for "brother" => (A) is found.

But as I work with Flexicontent, I would prefer to use the Flexicontent Search Plugin.

Any ideas to make it work ?
