thinking sphinx partially rebuilding index?

Question

After running a script to populate my database i ran a rake ts:rebuild but sphinx is partially rebuilding the indexes.

Stopped searchd daemon (pid: 23309).

What does it mean skipping non-plain index ?

Answer 1

Each of those are distributed indices, which contain the _core and _delta plain indices (e.g. episode contains both episode_core and episode_delta). There's nothing to do to index them directly, because distributed indices don't contain data, they just point to other indices.

In other words: what you're seeing is completely normal. All of your indices are being processed appropriately.

Sphinx used to have a slightly different message: Distributed index 'episode' can not be directly indexed; skipping - same deal.
