Change default language in search bar alone not entire site

[dineshphp]

Hi all,

 

I want some clarifications regarding searchbar in live store.

 

Unfortunately i could not able to search with language called "Tamil Language" ( is a kind of language in India ).

 

But all titles in site, are "Tamil Language".  That is not an issue. The problem arises only when someone search, by copy the title somewhere and paste in search bar then the final search result will be "Not Results Found".

 

Also I have attached a screenshot ( searchbar-issue.png ) for further reference.

So please advise any one to resolve this issue. Thanks in advance
