Hit filter using regular expression is not working as expected

Products

Issue

You have created a hit filter which is not working as expected, and one or more of the filter criteria are both using an asterisk (wildcard) as the match value and have the Regular Expression box checked.

Resolution

When using an asterisk (wildcard) only as the match value in your criteria, the Regular Expression box should be unchecked. A single asterisk is not a valid regular expression in Webtrends, but will work fine in most cases when interpreted as a wildcard character instead of a regular expression.
