Searched for several SKUs but datasheets/ listings are not filtered?

I searched several SKUs in Datasheet Maintenance/ Listing Maintenance page, but datasheets/ listings are not filtered by these SKUs, why?

When you entered multiple SKUs in search filter, separated by white space, in order to search for specific datasheets/ listings, but the results are not filtered at all, it still shows all datasheets/ listings, what happened?

Answer:

This is because you entered more than one white space between two SKUs.

This a normal one-space separated search filter

 And this is a multi-space separated search filter

 This will cause your search parameters to be invalid, please avoid using multiple spaces at any time.
