LIKE clauses belong in an array and are in the following format.

     array('$column [!~|=~] $pattern')

where $column is the column name, and $pattern is a simplified regex pattern. The regex pattern can contain the following items

'$' - end of string

'^' - begginning of string

'[$a|$b|$c...]' - matches either $a, or $b, or $c and so on

'[^$a|$b|$c...]' - matches NOT either $a, or $b, or $c and so on

'%' - Wildcard, meaning it matches anything
