Describe the solution you'd like We would like to add an option in the StringFieldComparisons to allow a filter object for a string to have a startsWith / endsWith / contains options.

Describe alternatives you've considered We are currently using the iLike option with combination of % in the beginning / end of the string to get the desired outcome, but we encountered some edge cases where the actual string contains %, so it's hard to distinguish between the cases where the % serves as a wildcard or when it's the actual string to be searched.

Having the startsWith / endsWith / contains options in the StringFieldComparisons interface would allow us to explicitly distinguish between the cases.
