query too complex, not enough stack (thread_stack=67K or higher required)

We are running into some limitations on some large queries and are exploring options. We will probably end up limiting the query on our end, but out of curiosity: is it possible to set the thread_stack value higher? What is it set to by default? Thanks!

    Hi Ben

    According to the Sphinx documentation, the default value is 64K:

    Presuming you're using Thinking Sphinx, you can configure this in config/thinking_sphinx.yml per environment (or config/sphinx.yml if you're using TS v1/v2). I'm currently not enforcing any limits for this, so you're certainly welcome to set it to what's needed (but also: don't go overboard, given you're on a shared server :) The Sphinx docs provide some detail on how to calculate that, but it's hard for me to advise anything specific without knowing what your queries are looking like.

    Let me know if you need any further help with this :)
