Search for accented characters , "ñ" and uppercase

Hey there,
The search component Edocman , does not find words with accents and uppercase words , including some special characters.
Is there any solution to this ?, on my joomla search from the website you can find easily this characters, so I gather that occurs only in the component.

Hi,
Please submit ticket and send your site information with super admin account, ftp account. I will check the problem for you.
Thanks
