Using this parameter will search for cases where an associated claim 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 claim 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 aren't sure of individual digits in the number.
