Regex filter does not allow to filter for ProductIdentifier "1234567-abcdefgh"

[dacky179]

Describe the bug
Our application does not have unique productidentifier. We have a combination of productidentifier and configurationkey.
After creation of the product with such a filter I mention 2 faulti behaviors:

• If I want to find the product in the ui by typing 1234567-abcdefgh i get no results.
• If I want to import new products i surely check if same product already exists. if a product with identifier "1234567" exists it will match to the check for "1234567-abcdefgh".

This behavior is caused by a regex check in ProductStorage.LoadTypes().

Expected behavior
I expected to find my product by exact identifier match

Additional context
I think It was added to allow contains, startwith, endwith and equals search with wildcards from UI.
I would prefer to allow change filter expression to be all but *.
I future I would suggest to move that funtiction to UI side:
let the user decide to search with regex or simplified with * wildchard.
if he choose simplified, the ui code replaces the * with a regex wildcard '.*'
the api always handles the entered string as a regex.

@Toxantron, @dbeuchler is it intentional, that the regex for the filter part in the pattern does not include the - character. I think nowhere else is this constraint enforced is it?

No, I think we just didn't think about this case. I like the idea of @dacky179 to support regex at all
