Question

In my situation, I have one web app with multiple databases; one DB per registered client. As these databases are created on user registration, I cannot manually add as these sources to sphinx config. But all databases has the same strucure and search queries are the same; just different database names and data of course. So, the question is;
Can sphinx be configured to fetch database list from e.g. ini or other external file and then make index for these databases? Then, can I pass database name in query to fetch results from specified db index?
Or there are other tools, other approaches for my problem?

There is a trick with a sphinx.conf file. If it is executable, Sphinx tries to execute it and accepts its output as the configuration. For example, you can merge several config file into a single one:

#!/bin/bash
# Sphinx configuration
cat /usr/local/etc/sphinx.d/*.conf

You can use this trick to build a config which indexes all your databases.
