- light sensors
- finds documents containing 'light' or 'sensors'
- light or sensors
- same as above
- light and sensors
- finds documents containing both 'light' and 'sensors'
- light not sensors
- finds documents containing 'light' but not 'sensors'
- (light not sensors) and Quantum
- finds documents containing 'Quantum', plus 'light' but not 'sensors'
- light*
- finds documents containing words starting with 'light'
