Question

I have installed Sphinx from source with pgsql and then installed thinking-sphinx gem(3.0.1) on my application (Rails 4.0.3). And I configured & generated the sphinx configurations. Then I added the indices on app/indices and later ran the index & start the sphinx via rake ts:index && ts:start, but I got the below error, let me know the way to resolve this.

rake ts:index

Generating configuration to /home/stc/presto/config/development.sphinx.conf

Sphinx 2.1.7-release (rel21-r4638)

Copyright (c) 2001-2014, Andrew Aksyonoff

using config file '/home/stc/config/development.sphinx.conf'...

FATAL: no indexes found in config file '/home/stc/config/development.sphinx.conf'

rake ts:start

In the log file I can see the below errors

Solution

Addressed this on the Thinking Sphinx Google group as well:

You seem to be using real-time indices - which is great - but that means you don’t need to use the ts:index task. The two main tasks that are useful are:

  • ts:generate - which adds/updates all documents in each real-time index.
  • ts:regenerate - which stops Sphinx, clears out existing index files, generates the configuration, starts Sphinx and runs ts:generate.

However, you’re also using either min_infix_len or min_prefix_len - and with Sphinx 2.1, the default dict setting doesn’t match with what is needed (as the logs detail). So, if you add dict: keywords to the appropriate environments in config/thinking_sphinx.yml and then run ts:regenerate, you should hopefully have a working Sphinx setup.
