• Starts With – Blocks users whose names begin with the entered text

• Equals To – Blocks users whose names exactly match the entered text

• Contains – Blocks users whose names contain the entered text somewhere in their name. Will also block exact matches

 

• Click the 'Add' button to apply your choice. The item will be added to the list with the category type displaying on the left side.

• To remove the search field, click the 'Search' link again.
