Google releases 'experimental' full-text search API for App Engine

The lack of full-text search has long frustrated developers

Google is testing a long-awaited full-text search API (application programming interface) for the Google App Engine, the company said on Tuesday.

The App Engine lets developers build web applications hosted on Google's infrastructure, and developers have long complained that the current search API is inadequate.

"Beside the cruel irony [of] not having full-text search I am starting to wonder why it would take Google so long to implement this," a developer wrote in the App Engine forum last month.

Google released the full-text search API in "experimental" mode and warned it could make changes in future versions that might be incompatible with the current API.

The API will allow users to search by keyword and delineate specific fields and ranges, Google said. The new capabilities also include scoring and snippeting.

Developers can use the API for free up to 20,000 calls a day or a total index size of 250 megabytes.

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.
