State (Search=>Filter=>other)
Use these fields to select waypoints located in a specific State, Province, or Territory. The drop-down menu allows you to choose whether the State name contains, does not contain, equal to, not equal to, or in list, compared with the text that you enter in the second field.
The in list operand allows you to select multiple states for inclusion. Each state name must be entered in full and separated by a ; (semi colon). For example, if you want to set a filter that has caches in only the states Alabama and California then select in list from the drop down box and enter "Alabama;California" (without the double quotes)
The text you enter in the second field is not case sensitive.
For complicated searches you may want to acquaint yourself with the Regex (Regular Expression) option.
