# SearchExpression
<a name="API_SearchExpression"></a>

A multi-expression that searches for the specified resource or resources in a search. All resource objects that satisfy the expression's condition are included in the search results. You must specify at least one subexpression, filter, or nested filter. A `SearchExpression` can contain up to twenty elements.

A `SearchExpression` contains the following components:
+ A list of `Filter` objects. Each filter defines a simple Boolean expression comprised of a resource property name, Boolean operator, and value.
+ A list of `NestedFilter` objects. Each nested filter defines a list of Boolean expressions using a list of resource properties. A nested filter is satisfied if a single object in the list satisfies all Boolean expressions.
+ A list of `SearchExpression` objects. A search expression object can be nested in a list of search expression objects.
+ A Boolean operator: `And` or `Or`.

 ** Filters **   <a name="sagemaker-Type-SearchExpression-Filters"></a>
A list of filter objects.  
Type: Array of [Filter](API_Filter.md) objects  
Array Members: Minimum number of 1 item. Maximum number of 20 items.  
Required: No

 ** NestedFilters **   <a name="sagemaker-Type-SearchExpression-NestedFilters"></a>
A list of nested filter objects.  
Type: Array of [NestedFilters](API_NestedFilters.md) objects  
Array Members: Minimum number of 1 item. Maximum number of 20 items.  
Required: No

 ** Operator **   <a name="sagemaker-Type-SearchExpression-Operator"></a>
A Boolean operator used to evaluate the search expression. If you want every conditional statement in all lists to be satisfied for the entire search expression to be true, specify `And`. If only a single conditional statement needs to be true for the entire search expression to be true, specify `Or`. The default value is `And`.  
Type: String  
Valid Values: `And | Or`   
Required: No

 ** SubExpressions **   <a name="sagemaker-Type-SearchExpression-SubExpressions"></a>
A list of search expression objects.  
Type: Array of [SearchExpression](#API_SearchExpression) objects  
Array Members: Minimum number of 1 item. Maximum number of 20 items.
