Filter Wildcards

When the Is Like or Is Not Like Filter Condition Types are used to filter a List such as an Events List, Alarm Summary, Queries List, or Historic List, you can include wildcard characters in the filter criteria. Wildcard characters allow a single filter value to match multiple Geo SCADA Expert database values. There are two wildcard characters:

• _ (underscore) matches any single character.

  For example CA_ will match CAT, CAN, CAB, but will not match CATCH, CALL or CA.

• % (percent) matches any number of characters.

  For example CA% will match CAT, CAN. CAB, CATCH, CALL or CA.

To include a wildcard character in a search without causing the wildcard to match other characters, enter a backslash (\) before the wildcard character. For example PUMP\_1 will only match PUMP_1, and will not match PUMP11, or PUMPA1.
