search query text field with Comma

[EXTERNAL Taminidi Ravi (ETI, Automotive-Service-Solutions)]

Hi users, This is may be a basic question, but I am facing some trouble.. 

The scenario is ,  I have a text  "Truck Series, 12V and 15V", if the user 
search "Truck Series" it is not getting the row , but "Truck Series," is 
working.. How can I get for search "Truck Series"..?

Thanks

Ravi
