The SearchOptions type exposes the following members.

## Constructors

| Name                       | Description                                            |
|----------------------------|--------------------------------------------------------|
| {{method}} SearchOptions() | Initializes a new instance of the SearchOptions class. |


## Properties

| Type                                 | Name   | Description                                                                              |
|--------------------------------------|--------|------------------------------------------------------------------------------------------|
| {{prop}} Dictionary\<string, object> | Keys   | The reference properties for searching the item which uniquely identifies the Entity.    |
| {{prop}} IEnumerable\<string>        | Expand | The Navigation property name(s) which should be expanded.                                |
| {{prop}} IEnumerable\<string>        | Select | Specifiy the properties which should be explicitly requested and returned by the client. |


## Remarks

The **Expand** property allows you to expand multiple navigation properties. By default, when the expand property is **not** specified then most Erp-systems reurn the entity without navigation properties.\
The **Select** property lets you receive only those properties which you want to have in the result.
