tons in letters for greeks

Hello!
The Greek language is using in every word tons in the letters as a result i have to rewrite the words without tons in order to use the search engine or to index my albums.
An example of what I am talking about is the word " Άννα " that has the ton in letter A in case that I will not remove the tone then it is not possible to index the word or even search it.
