From 53c86c43c4b8cba313335f5d70f7f77d4ab640d2 Mon Sep 17 00:00:00 2001 From: Brion Vibber Date: Tue, 3 Nov 2009 16:57:39 -0800 Subject: Bringing Sphinx search support up to code: broken out to a plugin, now supports multiple sites on a single server. Upgrade notes: * Index names have changed from hardcoded 'Identica_people' and 'Identica_notices' to use the database name and actual table names. Must reindex. New events: * GetSearchEngine to override default search engine class selection from plugins New scripts: * gen_config.php generates a sphinx.conf from database configuration (with theoretical support for status_network table, but it doesn't seem to be cleanly queriable right now without knowing the db setup info for that. Needs generalized support.) * Replaced old sphinx-indexer.sh and sphinx-cron.sh with index_update.php Other fixes: * sphinx.conf.sample better matches our live config, skipping unused stopword list and using a more realistic indexer memory limit Further notes: * Probably doesn't work right with PostgreSQL yet; Sphinx can pull from PG but the extraction queries currently look like they use some MySQL-specific functions. --- plugins/SphinxSearch/README | 45 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 45 insertions(+) create mode 100644 plugins/SphinxSearch/README (limited to 'plugins/SphinxSearch/README') diff --git a/plugins/SphinxSearch/README b/plugins/SphinxSearch/README new file mode 100644 index 000000000..5a2c063bd --- /dev/null +++ b/plugins/SphinxSearch/README @@ -0,0 +1,45 @@ +You can get a significant boost in performance using Sphinx Search +instead of your database server to search for users and notices. +. + +Configuration +------------- + +In StatusNet's configuration, you can adjust the following settings +under 'sphinx': + +enabled: Set to true to enable.
