This command allows for searching through keyboard/keymap targets, filtering by specific criteria. `info.json` and `rules.mk` files contribute to the search data, as well as keymap configurations, and the results can be filtered using "dotty" syntax matching the overall `info.json` file format.

For example, one could search for all keyboards using STM32F411:
For example, one could search for all keyboards powered by the STM32F411 microcontroller:

```
qmk find -f 'processor=STM32F411'
qmk find -f 'processor==STM32F411'
```

...and one can further constrain the list to keyboards using STM32F411 as well as rgb_matrix support:
The list can be further constrained by passing additional filter expressions:

```
qmk find -f 'processor=STM32F411' -f 'features.rgb_matrix=true'
qmk find -f 'processor==STM32F411' -f 'features.rgb_matrix==true'
```

The following filter expressions are also supported:
The following filter expressions are supported:

- `key == value`: Match targets where `key` is equal to `value`. May include wildcards such as `*` and `?`.
- `key != value`: Match targets where `key` is not `value`. May include wildcards such as `*` and `?`.
- `key < value`: Match targets where `key` is a number less than `value`.
- `key > value`: Match targets where `key` is a number greater than `value`.
- `key <= value`: Match targets where `key` is a number less than or equal to `value`.
- `key >= value`: Match targets where `key` is a number greater than or equal to `value`.
- `exists(key)`: Match targets where `key` is present.
- `absent(key)`: Match targets where `key` is not present.
- `contains(key, value)`: Match targets where `key` contains `value`. Can be used for strings, arrays and object keys.

You can also list arbitrary values for each matched target with `--print`:

```
qmk find -f 'processor=STM32F411' -p 'keyboard_name' -p 'features.rgb_matrix'
qmk find -f 'processor==STM32F411' -p 'keyboard_name' -p 'features.rgb_matrix'
```
