The name and email input fields in Filter form don't handle the space characters properly. For instance, if you fill in the name by two spaces and then you press the Filter button, the resulted member list is empty because the John Smith's name doesn't contain two spaces in a row. I think the values filled in there should be trimmed before further processing.

Furthermore, I think the inserted values should not disappear after clicking on the Filter button, that is a bit confusing. The values inserted in Filter form should be removed after clicking on Clear button only.
