Hi mtiwari,
This functionality is not possible with an OOTB Workdesk. Normally you would either use two search templates (one for each property) or your users would have to enter the value twice if being used in one search template. Literals in a standard search template cannot be filled during runtime, but are there to be filled with a predefined value in the template itself.
As solution for your request, you could try to code a custom field control for the second property field, which is active only in the search context and copies over the value from the first field after every character entered in the first field.
Best regards,
Dennis
