Description of Changes

Adds new search functionality to event transcript search, including strict search (use double quotes), negative search (put a ! before the double quotes), start filtering (put a ^ before the double quotes) and end filtering (put a $ before the double quotes).

For example, ^"1" $"2" "3" !"4" would only show strings that start with 1, end with 2, include 3, and don't include 4.
