Refining the programme

You need to make a revision (if there is a plugin, you can use it) of Redmine 2.5.2 software. In the application form RedMine must make a search. That is, it is necessary to search the list of customers by the entered symbols. (The current implementation of the drop-down list is not suitable.) Also make a bundle on the field Client address and contact phone. The search must be carried out by any of the 3 fields (Customer Name, Customer Address, Customer Contact Phone).
Set up in the Redmine system the receipt and registration of applications for letters.
Term of execution 5 working days.
