Python 2.7 has reached end of supportand will bedeprecatedon January 31, 2026. After deprecation, you won't be able to deploy Python 2.7applications, even if your organization previously used an organization policy tore-enable deployments of legacy runtimes. Your existing Python2.7 applications will continue to run and receive traffic after theirdeprecation date. We recommend thatyoumigrate to the latest supported version of Python.

Using the Python 2 Development Server

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

The Python 2 development server runs on your local machine and emulatesmost of the Search API's capabilities.

A few features are not available on the server. You should not attempt touse the following features when you run on the development server:

Functions in expressions

These functions are not available:

  • pow()

Stemming

Stemming of field values (for example "~cat") is not implemented. Thestem operator will be ignored and the value will be treated as an ordinaryexact match.

Tokenization

String fields in Asian languages are not tokenized on the development server.

Snippet() Expressions

The development server supports snippets, but the snippet selection andformatting algorithms are not the same as those used in a deployed app.Snippet results will not be exactly the same in the two environments.

Scoring

The match scoring mechanism is not implemented.

Diacriticals

Diacritical marks (such as accent marks) cannot be used in atom, text, and HTML fields.
