Multiple arguments with the filter command

Thanks to both Jim and Marielle for their awesome feedback. Instead of
asking specific questions about the details of your feedback, I want to
ask a general performance question. The filter does work within a
repeat loop like this:
repeat for each item thisItem in vInputStrings
filter it with ("*!*" & thisItem & "*!*")
put cr & it after vNewContainer
...do something with vNewContainer
But given that vInputStrings could be very large, my concern is that the
getting and putting involved would be dangerously memory- or
processor-intensive. What are the risks you have seen with the brute
force approach like the one above?

Subject: 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.
