The like match/fuzzy match will be used in combination with % and _.
% represents zero, one, or more characters.
_ represents a single character.
'a' // Precise matching, has the same effect as "="
'%a' // data ending with "a"
'a%' // data starting with "a"
'%a%' // data containing "a"
'_a_' // three-digit data with "a" as the middle character
'_a' // two-digit data with "a" as the last character
'a_' // two-digit data with "a" as the first character
'a__b' // four-digit data with "a" as the first character and "b" as the last characterExample
