When the index is created locally on a node it retrieves that schema from an internal store built into Riak and writes it to the directory specific to that index. The index uses the schema stored in its local directory. Updates to the schema are not automatically propagated to the local file. > More specifically, if I update a schema will those changes "propagate" to all > indexes using that schema? No, you will need to either need to delete the index and recreate or attach to the Riak console and run the following command: rp(yz_index:reload(<<"index_name">>)). This command will fetch the latest version of the associated schema for the index “index_name”, overwrite the index’s local schema, and then reload that index across the entire cluster. Why is this all so awkward? Some of the gory details can be found in these two issues if you really want to know: https://github.com/basho/yokozuna/issues/130 https://github.com/basho/yokozuna/issues/403 > > The reason I ask is I've been experimenting with simple searching and found > in the logs an error indexing a document due to unknown fields.

Yes, the schema itself has been updated but, as explained above, it is once removed from the index and not automatically reloaded. -Z
