Trouble with Riak Search JSON Extractor

Not getting any errors... but I did notice something interesting after
deleting the nodes on my system and then reconfiguring them.

If the first time I set up a schema I add the multivalued field in
question, everything works. If I then change the schema and then update it
over HTTP, the changes do not take affect.

For example, when I reconfigured the nodes on my system I added kept the
multivalued "groups" field I mentioned above. I then added some users and
was able to successfully retrieve them using q=groups:* or something more
specific. I then changed the schema from "groups" to "groups.id" and PUT it
on the server successfully (a subsequent GET returned the new schema). I
also updated the users so that the "groups" array was changed to an array
of JSON objects, each with an "id" field that would match the "groups.id"
field in the schema. I then tried to query the users using q=groups.id:*.
This failed.

Do changed to the schema not cause the solr indexes to update?

PS: I dug around in $RIAK/data/yz/user/conf and noticed a user.xml file.
The file held the ORIGINAL schema, not the updated one.
