Make search work on the basis of long string.

Make search work on the basis of long string.

I have created a form in Zoho creator. And in this form I have drop down fields containing data having large strings with special characters. I want to select one of the option listed in the drop down field and make the search happen. But as field contains large string with special characters so it is not possible to make the search work. Is there any way with which I can make the search working.
