Using this parameter will search for cases where an associated automobile license plate number matches the provided search string.

What qualifies as a match?

The search is not case-sensitive. For basic searches (i.e. those without wildcards), the search will return all cases where a license plate number associated with the case contains the provided search string.

For more flexibility in searching, you may use wildcards. These are symbols that represent either a single unknown character, or an unknown number (possibly zero) of unknown characters. The underscore character ("_") can be used in place of a single unknown character, and the percent character ("%") can be used in place of an unknown number of unknown characters. You may freely combine wildcards as needed. These wildcards can be helpful if you only have a partial plate number.
