# Display Filter Keywords

When creating custom filters, you can start with the keywords in the in the Display drop-down menu, and then add logical operators and variables.

In addition to the Display drop-down menu keywords, the following keywords can be used by typing them in the Display field:

- manual: Returns Views that have the training flag set to Always or Never.
- positive: Used with the Red Analyze tool, returns Views that have defects.
- negative: Used with the Red Analyze tool, returns Views that do not have defects.
- 'filename_word': Returns Views that have filenames which contain a word. For example, if you had curated images in your Training Set that were named "bad_head_001.png", "bad_head_002.png", etc. To return only the Views that contained the word "bad_head" in the filename, you would enter 'bad_head' into the Display field.
