Implementing Sphinx

MageStack natively supports Sphinx, in order to take advantage of it, you need to do 2 things,

1. Enable Sphinx for the vhost (contact a member of the support team to do this)
2. Ensure that you have placed the Sphinx configuration files in the correct directory (see below)

Sphinx Configuration Details

Hostname:  sphinx1.i
Port:      9315

SphinxQL Configuration Details

Hostname:  sphinx1.i
Port:      9316

Sphinx configuration file locations

There are 3 main configuration files we observe when building a Sphinx core for your vhost

The following directory must exist (adjust example.com to suit),

/microcloud/domains/example/domains/example.com/http/lib/Sphinx

Then within that, the following configuration files are valid,

wordforms.txt
stopwords.txt
synonyms.txt
sphinx.conf

Once you have added/updated these files, we can (re-)build your Sphinx core.

Default Sphinx configuration

If you haven't specified your own Sphinx configuration, we use the following defaults (as is used on the example.com demo store on MageStack), the fields

source magento_examplecom {
  type = mysql
  sql_host = %%DBNAME%%
  sql_user = %%DBUSER%%
  sql_pass = %%DBPASS%%
  sql_db   = %%DBHOST%%
  sql_port = 3306
  sql_sock = /var/lib/mysql/mysql.sock
  sql_query_pre = SET NAMES utf8;
  sql_query     = SELECT CONCAT(product_id, store_id) AS id, catalogsearch_fulltext.* FROM catalogsearch_fulltext
  sql_attr_uint = product_id
  sql_attr_uint = store_id
}

index examplecom {
  source = magento_examplecom
  path = %%SPHINXDIR%%/sphinx.index
  morphology   = stem_en, metaphone
  min_word_len = 1
  charset_type = utf-8
  blend_chars  = -
  blend_mode   = trim_both
  html_strip   = 1
  stopwords     = /microcloud/data/mysql/sphinx/examplecom/stopwords.txt
  exceptions    = /microcloud/data/mysql/sphinx/examplecom/synonyms.txt
  wordforms     = /microcloud/data/mysql/sphinx/examplecom/wordforms.txt
}

Using Variables in Configuration file

There are a number of pre-defined variables so that you can use to make management easier, they should be wrapped in %% characters as shown:

• %%DBHOST%% - The database host (as stored in your local.xml)
• %%DBNAME%% - The database name (as stored in your local.xml)
• %%DBUSER%% - The database username (as stored in your local.xml)
• %%DBPASS%% - The database password (as stored in your local.xml)
• %%CLEANTLD%% - This is the vhost domain name, with all non a-zA-Z0-9 characters removed (Eg. examplecom)
• %%INDEX_NAME%% - Same as the CLEANTLD variable
• %%GROUP%% - The domain group name (eg. example)
• %%TLD%% - The vhost top level domain, as defined in its directory path (eg. example.com)
• %%SPHINXDIR%% - This is the path to the Sphinx index, it is automatically populated based on the index name (eg. examplecom)
