xapian-haystack 1.1.1beta

A Xapian backend for Haystack

Overview

xapian-haystack is a backend for use with the Django Haystack search API.

More information on Haystack can be found here: http://haystacksearch.org/

xapian-haystack is licensed under the GPL, please see the included LICENSE file for more information.

Requirements

• Python 2.4 (May work with 2.3, but untested)

• Django 1.0.x

• Django-Haystack 1.0BETA

• Xapian 1.0.13+ (May work with earlier versions, but untested)

• mod_wsgi 1.3.X

Notes

• Due to an issue with mod_python possibly causing deadlocks with Xapian (http://trac.xapian.org/ticket/364), when the Python is not invoked through the “main interpreter”, mod_python is not supported with xapian-haystack. It may work, with some tweaking, but your mileage will vary.

• Because Xapian does not support simultaneous WritableDatabase connections, it is strongly recommended that users take care when using RealTimeSearchIndex to either set WSGIDaemonProcess processes=1 or use some other way of ensuring that there are not multiple attempts to write to the indexes. Alternatively, use SearchIndex and a cronjob to reindex content at set time intervals (sample cronjob can be found here: http://gist.github.com/216247) or derive your own SearchIndex to implement some other form of keeping your indexes up to date.
