  • Reference

Definition

Namespace:
Microsoft.Azure.Search.Models
Assembly:
Microsoft.Azure.Search.Service.dll
Package:
Microsoft.Azure.Search.Service v10.1.0
Source:
FieldMappingFunction.Customization.cs

Creates a field mapping function that transforms a string formatted as a JSON array of strings into a string array that can be used to populate a Collection(Edm.String) field in the index.

public static Microsoft.Azure.Search.Models.FieldMappingFunction JsonArrayToStringCollection ();
static member JsonArrayToStringCollection : unit -> Microsoft.Azure.Search.Models.FieldMappingFunction
Public Shared Function JsonArrayToStringCollection () As FieldMappingFunction

Returns

FieldMappingFunction

A new field mapping function.

Remarks

For example, if the input string is ["red", "white", "blue"], then the target field of type Collection(Edm.String) will be populated with the three values red, white and blue. For input values that cannot be parsed as JSON string arrays, an error will be returned.

Sample use case: Azure SQL database doesn't have a built-in data type that naturally maps to Collection(Edm.String) fields in Azure Search. To populate string collection fields, format your source data as a JSON string array and use this function.
