 The following filters are supported by all tables based on the data type
 of the column.
 
-+------------+------------------+------------+
-| Data type  | Possible Filter  | Example    |

-| Text       | Any characters   | Test,      |

-|            | used. The \*     |            |
-|            | acts as a        |            |
-|            | wildcard and can |            |

+|                  | character. Both wildcards can |                  |
+|                  | be used in the same query.    |                  |
