Turn down sensitivity of URLParams

**Issue Type:**
Enhancement

**Platform:**
Web

**Description:**
While using the text field with URLParams every single character/key press adds to the URL so if you say type in "cheese" into the box and press the back button you have to press it once for every single character (so pressing it once results in "chees", etc). I don't think this makes sense, it should be an entire word or something?

**Screenshots:**
No screenshots sorry

**Minimal reproduction of the problem with instructions:**
Description should explain it

**Reactivesearch version:** 2.6.2

**Browser:** all

**Anything else:** Nothing else
