Hi Steffen,
Greetings from Syncfusion support.
By default
filtering will be performed in Grid based on the exact filterkey entered for
filtering and by applying any of our available filter operators. This is the
default behavior of performing filtering action in grid.
Please
refer to the below documentation for more details on the available filter
operators in grid.

Please get back to us if you need further assistance.
Regards,
Renjith R
