Data Types - Azure Cognitive Search

Azure Cognitive Search supports the following data types:

Edm.String​

Edm.String is used for text data. This data type is commonly used for fields such as names, descriptions, and titles.

Edm.String
{
    "name": "productTitle",
    "type": "Edm.String",
    "searchable": true,
    "filterable": true,
    "sortable": true,
    "facetable": true,
    "retrievable": true
}

Edm.Int32 and Edm.Int64​

Edm.Int32 and Edm.Int64 are used for integer data. Edm.Int32 supports values from -2,147,483,648 to 2,147,483,647, while Edm.Int64 supports values from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807. These data types are commonly used for fields such as prices, quantities, and ratings.

Edm.Int32
{
    "name": "productPrice",
    "type": "Edm.Int32",
    "filterable": true,
    "sortable": true,
    "facetable": true,
    "retrievable": true
}

Edm.Double​

Edm.Double is used for floating-point numeric data. This data type is commonly used for fields such as prices, weights, and measurements.

Edm.Double
{
    "name": "productWeight",
    "type": "Edm.Double",
    "filterable": true,
    "sortable": true,
    "retrievable": true
}

Edm.Boolean​

Edm.Boolean is used for Boolean data. This data type is commonly used for fields that indicate true or false, such as availability or product status.

Edm.Double
{
    "name": "productAvailability",
    "type": "Edm.Boolean",
    "filterable": true,
    "sortable": true,
    "facetable": true,
    "retrievable": true
}

Edm.DateTimeOffset​

Edm.DateTimeOffset is used for date and time data. This data type is commonly used for fields such as created dates, modified dates, and expiration dates.

Edm.DateTimeOffset
{
   "name": "productCreatedDate",
   "type": "Edm.DateTimeOffset",
   "filterable": true,
   "sortable": true,
   "retrievable": true
}

Edm.GeographyPoint​

Edm.GeographyPoint is used for geospatial data. This data type is commonly used for fields that store latitude and longitude information, such as location data.

Edm.GeographyPoint
{
   "name": "productLocation",
   "type": "Edm.GeographyPoint",
   "retrievable": true
}

Collection data types​

Collection data types allow you to store arrays of data in a single field. For example, if you have a field that stores multiple categories for a product, you can define it as Collection(Edm.String).

Collection(Edm.String)
{
   "name": "productCategories",
   "type": "Collection(Edm.String)",
   "filterable": true,
   "facetable": true,
   "retrievable": true
}

Applies to Collection(Edm.Int32), Collection(Edm.Int64), Collection(Edm.Double), Collection(Edm.Boolean), Collection(Edm.DateTimeOffset), Collection(Edm.GeographyPoint)
