In some areas of the system we can use a system of 'Wildcards' while searching.
123% Will find anything starting with 123 (Note: This is standard in many searches)
%345 Will find anything ending with 345 (or 345 within if already using wildcard at end)
%345% Will find anything with 345 in it anywhere
12_345 Will find if any single character instead of underscore (Can use multiple times)
12 Will find if 3rd character is any in the group within the square brackets
