The SortOptions Class

Stay organized with collections Save and categorize content based on your preferences.

Class SortExpression represents a multi-dimensional sort of Documents.

This API is supported for first-generation runtimes and can be used when upgrading to corresponding second-generation runtimes. If you are updating to the App Engine Python 3 runtime, refer to the migration guide to learn about your migration options for legacy bundled services.

The following code shows how to sort documents based on product rating in descending order and then cheapest product within similarly rated products, sorting at most 1000 documents:

     SortOptions(expressions=[
         SortExpression(expression='rating',
             direction=SortExpression.DESCENDING, default_value=0),
         SortExpression(expression='price + tax',
             direction=SortExpression.ASCENDING, default_value=999999.99)],
         limit=1000)

SortOptions is defined in the google.appengine.api.search module.

Constructor

Arguments

expressions: An iterable of SortExpression representing a multi-dimensional sort of Documents.
match_scorer: A match scorer specification which may be used to score documents or in a SortExpression combined with other features.
limit: The limit on the number of documents to score. It is advisable to set this limit on large indexes.

Result value

A new instance of class SortOptions.
