# Usage

## Filter AAS Collection
This feature displays AAS in which a certain search text occurs. The search refers to the name, the identification and the endpoint type of the AAS.

A search within the structure of an AAS is started if the search text begins with a `#`. It is possible to search for a specific model type with a specific name and, depending on the model type, a specific value. The search text has the following format:

`#<abbreviation>:<idShort>[=, !=, <, <=, >=, >]<value>`
 
`#<abbreviation>:<idShort>=<min>...<max>`

## Examples
All AAS that contain at least one operation element:

`#Opr`

All AAS that contain at least one submodel with the name *Nameplate*:

`#SM:Nameplate`

All AAS that contain at least one property with the value *SmartFactoryOWL*:

`#Prop=SmartFactoryOWL`

All AAS that contain at least one property with the name *Producer* and the value *SmartFactoryOWL*:

`#Prop:producer=SmartFactoryOWL`

All AAS where *RotationSpeed* is greater or equal then *5000*:

`#Prop:RotationSpeed >= 5000`

All AAS where *ProductionDate* is between *12/24/2022* and *12/31/2022*:

`#Prop:ProductionDate = 12/24/2022...12/31/2022`
