Cool! Understood :)
Thanks!

Hi Sean,
I didn't created the bucket_type as a map datatype as at first i was just
testing simple Riak Search... then it occurred to me what if I want a
counter in the data? :)
Your example is pretty straightforward to follow and simple. Just 2
questions:
1. key.counters['number'].increment(1) = No need to define a counters
data-type somewhere before putting it inside the map as we normally need
in
simple buckets? If it works automatically is great :)
Yes, it works automatically. All included datatypes are available inside
maps.
2. if we use number_counter instead of number_i does Search/SOLR
understand is an integer? in case you want to do a range... as somewhere
in
the docs I read that better to use _s for strings, _b for binary,
_i
for integers, etc... so SOLR knows how to treat the data... I believe
there
will be no strange behaviours for having _register instead of _s and
_counter instead of _i, right?
The default Solr schema that ships with Riak accounts for these
datatypes automatically and uses the appropriate index field type:
https://github.com/basho/yokozuna/blob/develop/priv/default_schema.xml#L96-L104
If you write your own schema, you will want to include or change the
schema fields appropriately.
Thanks!

Alex,
Assuming you've already made your bucket-type with map as the
datatype, then bucket.new() will return you a Map instead of a
RiakObject. Translating your example above:
key = bucket.new('lionelmessi')
key.registers['name'].assign('Messi')
key.registers['team'].assign('Barcelona')
key.counters['number'].increment(10)
key.store()
Note that because Maps are based on mutation operations and not
replacing the value with new ones, you can later do this without
setting the entire value:
key.counters['number'].increment(1)
key.store()
This will also change your searches, however, in that the fields will
be suffixed with the embedded type you are using:
r = client.fulltext_search('ix_footballers', 'team_register:Barcelona')
Hope that helps!

Imagine I have a Riak object footballer with some static fields:
name,
team, number. I store them like this now:
1: CREATE INDEX FOR RIAK SEARCH
curl -XPUT http://148.251.140.229:8098/search/index/ix_footballers;
2: CREATE BUCKET TYPE
riak-admin bucket-type create tp_footballers
'{props:{allow_mult:false,search_index:ix_footballers}}'
riak-admin bucket-type activate tp_footballers
3: INSERT A PLAYER
bucket = client.bucket_type('tp_footballers').bucket('footballers')
key = bucket.new('lionelmessi', data={'name_s':'Messi',
'team_s':'Barcelona', 'number_i':10}, content_type='application/json')
key.store()
4: SEARCH FOR BARCELONA PLAYERS
r = client.fulltext_search('ix_footballers', 'team_s:Barcelona')
So far so good :) BUT... what if I want to have a field goals_i that
is a
counter that will be incremented each match day with the number of
goals
he
scored? What is the syntax/steps to do to set up footballers as a
MAP
and
then put a COUNTER inside? I know is possible as I read it in some
data
dump
some Basho employee passed me some time ago, but I can't manage to see
how
to do it now.
Thanks!
Alex
