Advanced Search with Sphinx and MySQL

Vlad Fedorkov and the creator of Sphinx Search speaking at Percona Live 2014. They cover the basics of Sphinx, as well as faceted search, auto-correction, searching with ranges, geo spatial search, non-full-text search (filtering, grouping, sorting), and about some of Sphinx’s full-text search operators (ie. field-limit operator and quorum operator). A talk at Percona Live […]

MySQL & Sphinx: Register now for Nov. 20 Webinar

Sphinx is a free, open-source search server that integrates nicely with MySQL. It provides a fast, scalable, and pluggable search framework. The Sphinx engine possesses a variety of tools enabling you to customize how searching/indexing interacts with or becomes a part of your environment.

Join me and Sphinx Search CEO/CTO Andrew Aksyonoff, the founder and creative force behind Sphinx, on Wednesday, November 20th at 10 a.m. PST as we discuss how to get started with Sphinx and seamlessly integrate it into your applications and MySQL. The title of our webinar is, “How to Optimally Configure Sphinx Search for MySQL” and you can register …

What technologies are you running alongside MySQL?

In many environments MySQL is not the only technology used to store in-process data.

Quite frequently, especially with large-scale or complicated applications, we use MySQL alongside other technologies for certain tasks of reporting, caching as well as main data-store for portions of application.

What technologies for data storage and processing do you use alongside MySQL in your environment? Please feel free to elaborate in the comments about your use case and experiences!

Note: There is a poll embedded within this post, please visit the site to participate in this post's poll.

Sphinx search performance optimization: multi-threaded search

Queries in MySQL, Sphinx and many other database or search engines are typically single-threaded. That is when you issue a single query on your brand new r910 with 32 CPU cores and 16 disks, the maximum that is going to be used to process this query at any given point is 1 CPU core and 1 disk. In fact, only one or the other.

Seriously, if query is CPU intensive, it is only going to be using 3% of the available CPU capacity (for the same 32-core machine). If disk IO intensive – 6% of the available IO capacity (for the 16-disk RAID10 or RAID0 for that matter).

Let me put it another way. If your MySQL or Sphinx query takes 10s to run on a machine with a single CPU core and single disk, putting it on a machine with 32 such cores and 16 such disks will not make it any better.

But you knew this already. Question is – can you do something about it?

In case of Sphinx – indeed you can! And with very little …

Sphinx search performance optimization: attribute-based filters

One of the most common causes of a poor Sphinx search performance I find our customers face is misuse of search filters. In this article I will cover how Sphinx attributes (which are normally used for filtering) work, when they are a good idea to use and what to do when they are not, but you still want to take advantage of otherwise superb Sphinx performance.

The Problem

While Sphinx is great for full text search, you can certainly go beyond full text search, but before you go there, it is a good idea to make sure you’re doing it the right way.

In Sphinx, columns are basically one of two kinds:

a) full text
b) attributes

Speaking in MySQL terms, Full text columns are always indexed and using the very …

MariaDB Foundation

You may have already seen the announcement MariaDB Foundation to Safeguard Leading Open Source Database. We at Open Query wholeheartedly support this (r)evolution of the MySQL ecosystem, which appears to be increasingly necessary as Oracle Corp is seriously dropping the ball with security updates and actually just general development and innovation. Oracle has actually done some very good work, I happily acknowledge that – but security issues are critical, having crashing bugs and incorrect query results in a .28 of a GA release is uncool, and not incorporating awesome development efforts by the community is just astonishing.

MariaDB is where the Sphinx fulltext …

Webinar for Full Text Search Throwdown

Tomorrow, August 22 at 10:00am PDT, I’ll present a webinar called Full Text Search Throwdown.  This is a no-nonsense performance comparison of solutions for full text indexing for MySQL applications, including:

  • LIKE predicates and regular expressions
  • MyISAM FULLTEXT indexes
  • InnoDB FULLTEXT indexes
  • Apache Solr
  • Sphinx Search
  • Trigraphs

I’ll compare the performance for building indexes and querying indexes.

If you’re developing an application with text search features, this will be a very practical and informative overview of your technology options!

How to offload MySQL server with Sphinx by Vladimir Fedorkov

Vladimir Fedorkov of Sphinx.

Presentation started out with a very nice presentation of candies to all the audience members.

What is Sphinx? Another (C++) daemon on your boxes. Can be queried via API (PHP, Python, etc.) or MySQL-compatible protocol and SQL queries (SphinxQL). Some query examples are in the slides, here’s one about SphinxSE in the KB.

MyISAM FTS is good but becomes slow with half a million documents. InnoDB has FTS now but he’s not tried it (and neither has anyone in the audience to see it compare with MyISAM FTS).

Geographical distance is the distance measuring the surface of the earth (two pairs of float values – latitude, longitude). In Sphinx, there is support for GEODIST(Lat,Long,Lat2,Long2) in Sphinx.

Segments are good for price ranges on a site, date …
