I have a list of objects. In my case, the object is a contract (agreement). The contract has address field as string
I want to make it possible to filter by address. Or rather, the user enters the beginning or part of the address and the table is filtered based on the user input text. The problem is that the user can enter with a capital or small letter or something else, and thus strict equality does not work. I need a matching address with user input.
Data structure:
Input box controller:
This input box controller works only then user put exactly the same address as in data structure, for example Juhkentali tn 32, Tallinn. But my idea is, that user can enter only juhkentali and will see all contract with matched address
Please help me, how I could solve this problem.
