Strange behavior with RealName module

Hi,

I make field for "User" type. Select "Autocomplete" widget (match operator = CONTAINS). Try write in field from node create page.

I have user "Sergei Labutin" with username "Sergei".

i enter "se" and see in list for autocomplete "Sergei Labutin" but if i type "la" i not see any variants. Module find only by username. In RealName exist function for autocomplete by realname.

You can add in settings option for search by field for we can change behavior. Or make support RealName module.

I think better make as "sort property" but for searsh settings. See attach

Best Regards,
Sergei.
