Parameters

Pattern

The regular expression pattern to search for.

Occurrence

The occurrence (rank) of the searched expression on the current page. Set the occurrence to 1 if you are searching for the first occurrence, set it to 2 for the second etc.

Rank equal to 0 is not accepted, it will always be converted to 1. Please note that the occurrence (rank) is always related to the current page.

CaseSensitive

Set this parameter to true if you want to apply case-sensitive search, otherwise set it to false.

BoundingBoxes

Output parameter. If the searched expression has been found, this parameter will output an IEnumerable of rectangle areas that surround the occurrence in inches.

Return Value

It is recommend to use the GetStat method to identify the specific reason for the method's failure, if any.
