Sphinx

Creating and maintaining a Sphinx index on your MySQL table.

• Installing Sphinx alongside MariaDB

Download and install from binaries.

Create a Linux user: `sphinxsearch` Create a folder /var/sphinxsearch/

Copy config file sphinx.conf to /var/sphinxsearch/ containing:

sphinx.conf example

chown -R sphinxsearch:sphinxsearch /var/sphinxsearch

• Adding a MariaDB internal client for Sphinx

In MariaDB:

`INSTALL SONAME 'ha_sphinx';` (only once, to install the engine)

`CREATE DATABASE sphinx;` (only once per project, could be named sphinx_sku)

USE sphinx; CREATE TABLE sku_attributes (

   id BIGINT UNSIGNED NOT NULL,
   weight  INTEGER NOT NULL,
   query   VARCHAR(3072) NOT NULL,
   group_id  INTEGER,
   INDEX(query)

) ENGINE=SPHINX CONNECTION="sphinx://127.0.0.1:9312/sku_attributes";

Once every time we add an index to Sphinx. This table is our MariaDB gateway to query the Sphinx index.

Adding another index: USE sphinx; CREATE TABLE sku_products (

   id BIGINT UNSIGNED NOT NULL,
   weight  INTEGER NOT NULL,
   query   VARCHAR(3072) NOT NULL,
   group_id  INTEGER,
   INDEX(query)

) ENGINE=SPHINX CONNECTION="sphinx://127.0.0.1:9312/sku_products"

• Creating an index with MySQL source.
• Populating the index.
• Updating the index.

• Creating a Real Time index.
• Updating the index.

• Querying the index alone.

`SELECT * FROM sphinx.sku_attributes WHERE query="simple and easy to install";`

• Joining the results with MariaDB records.

Querying the index but fetching data directly from our MariaDB equivalent table:

SELECT * FROM sphinx.sku_attributes sp_a LEFT JOIN sku_io.product_attributes pa ON pa.id = sp_a.i d WHERE sp_a.query="simple and easy to install";
