Multiple arguments with the filter command

Another text filtering question, please. I have studied the archives
but have not found precisely the solution that works.
I have a container vContainer of file names, each line of the form
Here are three literal examples:
C:/The World/Europe/!?!Map of Europe.jpg!/3536844/1155845730
User-input text strings can define what files from vContainer are to be
retained. The following works to filter-in the first example above:
filter vContainer with ("*!*.ps*!*")
However, if the user wants both ".ps" and "Europe" to be retained, how
best to do it without repeat loops and a lot of temporary copies of
vContainer? Is there a way?
One catch is that if the user inputs something like "53", the operation
must recognize the fact that the "53" in the first two examples is not a
part of the file name, thereby filtering them out, but that "53" is a
part of the file name in the third example, thereby filtering it in.
This is one reason for the exclamation point tokens in vContainer.
Any ideas greatly appreciated.
