search interface not allow to specify many solr specific properties which works nice via http interface [JIRA: CLIENTS-492]

[mogadanez]

we are use at least:

  'facet',       
  'facet.field',
  'facet.query',
  'stats',
  'stats.field',
  'group',
  'group.field',
  'group.main',
  'group.sort',
  'group.limit'

[mogadanez]

but it works de-facto 25.06.2015 19:09 пользователь "bkerley" notifications@github.com написал:

Yokozuna/Riak Search doesn't support facets and grouping. We use Solr for the initial search, but Yokozuna aggregates search results from multiple sources into a single response, and doesn't implement faceting and grouping.

Tested right now.

1. create new cluster with 5 nodes
2. setup search like a sample(http://docs.basho.com/riak/latest/dev/using/search/#Simple-Setup)

export RIAK_HOST="http://localhost:8098"
curl -XPUT $RIAK_HOST/search/index/famous  
riak-admin bucket-type create animals '{"props":{}}'
riak-admin bucket-type activate animals

1. add some test data

curl -XPUT $RIAK_HOST/types/animals/buckets/cats/keys/liono \
     -H 'Content-Type: application/json' \
     -d '{"name_s":"Lion-o", "age_i":30, "leader_b":true}'

curl -XPUT $RIAK_HOST/types/animals/buckets/cats/keys/cheetara \
     -H 'Content-Type: application/json' \
     -d '{"name_s":"Cheetara", "age_i":28, "leader_b":false}'

curl -XPUT $RIAK_HOST/types/animals/buckets/cats/keys/snarf \
     -H 'Content-Type: application/json' \
     -d '{"name_s":"Snarf", "age_i":43}'

curl -XPUT $RIAK_HOST/types/animals/buckets/cats/keys/panthro \
     -H 'Content-Type: application/json' \
     -d '{"name_s":"Panthro", "age_i":36}'

curl -XPUT $RIAK_HOST/types/animals/buckets/cats/keys/liono1 \
     -H 'Content-Type: application/json' \
     -d '{"name_s":"Lion-o1", "age_i":30, "leader_b":true}'

curl -XPUT $RIAK_HOST/types/animals/buckets/cats/keys/cheetara1 \
     -H 'Content-Type: application/json' \
     -d '{"name_s":"Cheetara1", "age_i":30, "leader_b":false}'

curl -XPUT $RIAK_HOST/types/animals/buckets/cats/keys/snarf1 \
     -H 'Content-Type: application/json' \
     -d '{"name_s":"Snarf1", "age_i":43}'

curl -XPUT $RIAK_HOST/types/animals/buckets/cats/keys/panthro1 \
     -H 'Content-Type: application/json' \
     -d '{"name_s":"Panthro1", "age_i":28}'

compare queries via internal_solr and pony and yokozuna front-end: riak1/internalsolr/famous/select?q=:_&rows=0&indent=true&facet=true&facet.field=age_i

This confirm your point that it is different data on different nodes

then try to test on youkozuna endpoint: [riak1|riak2|riak3|riak4|riak5]search/query/famous?q=:&fl=name_s&rows=0&facet=true&facet.field=age_i

all of them returns same result: (full result)

so it is collect and join facet data from all nodes

[lukebakken]

@mogadanez thank you for the detailed test.

Currently, the inability to perform facet searches is a limitation in Riak. I will investigate to see if there is a plan to add this to Riak.

[mogadanez]

in sample above I show that its works fine via http interface.

[lukebakken]

Correct, but the Node.js and other Riak clients use Riak's protocol buffers interface, which does not support facet parameters. I'll post an update when I learn more.

[mogadanez]

found related issue https://github.com/basho/riak_pb/issues/72

[lukebakken]

@mogadanez - I have forwarded your request onto product management. Facet query support via protocol buffers is under investigation for inclusion in a future Riak release.

At this time, querying Riak via HTTP (as you have shown) is the current way to do facet queries.

Thanks.
