# Display Filter Logical Operators

Keywords (and conditions) can be used in conjunction with logical operators to build custom selection filters. The three basic logical operators, not, and, or, are available to construct custom filters.

Example | Description

not trained | Returns Views that are not used for training.
good and not 'good' | Returns Views labeled as good and whose image filename does not contain the word 'good'.
labeled or not manual | Returns Views that are labeled and/or whose training flag is set to Auto.
