When multiple criteria are specified, these are logically linked with and. For text fields it is sufficient to enter only a portion of the search text. It is also not necessary to consider lower or upper case spelling. Wildcards, such as * or ? are not supported.
If the filter is activated, the icon is shown as a pressed button. Clicking again removes the filter. Another click calls up the input dialog, which is initialized with the last entered values.
