Next choose a document attribute to match against, either a metadata element or the name of the file in question. Enter a regular expression to use during the matching. You can toggle between "Including" documents that match the filter, or "Excluding" them. Finally, you can specify any of the standard PERL regular expression flags to use when matching (e.g. "i" for case-insensitive matching). Finally, click "Add" to add the filter to the "Defined Subcollection Filters" list.
