I have it working now. Here's what I had to do.
1) Define a schema file for my bucket.
2) Set it with "./search-cmd set-schema {bucket-name} {file-path}".
3) Learn that when referencing nested fields in JSON structures, all
ancestor names must be included and separated with underscores. I didn't
see that in any documentation, but learned it from the presentation video
at http://nosql.mypopescu.com/post/5475701359/riak-search-explained.
4) When PUTing JSON, put double-quotes around keys. It's JSON, not
JavaScript literal object syntax.
Here's the schema I created. Note the field name "address_zip".
%% Schema for 'users'
{
schema,
[
{version, "1.1"},
{n_val, 3},
{default_field, "name"},
{analyzer_factory, {erlang, text_analyzers,
whitespace_analyzer_factory}}
],
[
%% Field named "zip" is are indexed as integer
{field, [
{name, "address_zip"},
{type, integer},
{analyzer_factory, {erlang, text_analyzers, integer_analyzer_factory}}
]},
%% Everything else is a string
{dynamic_field, [
{name, "*"},
{type, string},
{analyzer_factory, {erlang, text_analyzers,
whitespace_analyzer_factory}}
]}
]
}.
I hope this helps someone in the future!
