Sphinx for Rotation\Tube sites

Basically script uses mysql to search DB, but on large DB mysql too slow. + it doesnt use morphology.

Sphinx (sphinxsearch.com) - is an open source full text search server, designed from the ground up with performance, relevance (aka search quality), and integration simplicity in mind. It faster then Mysql and deliver better quality of results.

Setup

  • Ask admin to setup sphinx
  • create folder scj/sphinx
  • ask admin to add scj index into sphinx config. (See config example below )
  • Run indexer (or ask admin to do it)
     indexer --all --rotate 
  • In Rotation - Settings edit sphinx options.

That's it.

Note if you change DB (add\remove content) - please, run indexer every day to keep it's base up to date.

Add to cron something like (ask admin)

indexer --all --rotate

addition of mysql41 is the most important part. It's called SphinxQL

You have to edit here:

scj_mysql_login
scj_mysql_password
scj_db
path_to_data

Sphinx Delta Config

For Version 2.X

This part make sense only if you have a really big DB (1M+ , for example a demo version bigbase.smartcj.com has 12M+ galleries)

When Sphinx creates an index it takes a snapshot of a current state of a DB. So if something has been changed since then - it won't be reflected in index. And if you have a big DB it takes a lot of time to reindex it.

So the good idea is to just reindex those parts that have been changed. That's why you need so called delta index

To make use of it you need to add after

sql_query_pre = SET NAMES utf8

a new line

sql_query_pre = UPDATE rot_settings SET value = (SELECT MAX(gallery_id) FROM rot_gallery_info) WHERE name = 'sphinx_max_gallery_id'

And add a new source

source delta : your_name_source
{
    sql_query_pre = SET NAMES utf8

	sql_query				= SELECT gi.gallery_id, UNIX_TIMESTAMP(gi.activation_date) as date, alt, description, gi.duration, sponsor_id, gs.total_ctr, gi.content_type, \
							(SELECT group_concat(tag_name) FROM rot_gal2tag g2t \
							LEFT JOIN rot_tags as t on t.tag_id = g2t.tag_id \
							WHERE g2t.gallery_id = gi.gallery_id) as tags, \
							(SELECT group_concat(gss.group_id) FROM rot_gallery_stats1 as gss \
							WHERE gss.gallery_id = gi.gallery_id AND group_id != 0) as categories \
							FROM rot_gallery_info AS gi \
							JOIN rot_gallery_data1 AS gd ON gi.gallery_id = gd.gallery_id \
							JOIN rot_gallery_stats1 AS gs ON gs.gallery_id = gi.gallery_id \
							WHERE gi.gallery_id > ( SELECT value FROM rot_settings WHERE name = 'sphinx_max_gallery_id' ) \
							AND gallery_status = 'active' and gallery_type = 0 \
							and gs.best_thumb = 'yes' and gs.group_id = 0
    
}


index delta : your_name_index
{
    source = delta
    path = /your_full_path/data/delta
}

You can note that it has the same query with an addition of sphinx_max_gallery_id.

Now you have to add a new crontab task that will reindex new parts

indexer --rotate delta

Now you have to add 'delta' into Sphinx Delta Index (Rotation settings)

once a day you can marge main index and delta index

indexer --rotate --merge your_name_index delta

That's it.
