[p11o]

When getting a search response on a text_tsd field, I am getting a 0 when the expected value is an empty string.

search response when there is an empty string in the text_tsd field

{
"score":1.1388365,
"_yz_rb":"dev-message",
"_yz_rt":"default",
"_yz_rk":"L6XMFEoolh2zvMPpIFoaxizL2qv",
"_yz_id":"1*default*dev-message*L6XMFEoolh2zvMPpIFoaxizL2qv*41",
"text_tsd":0,
}

value in riak kv for L6XMFEoolh2zvMPpIFoaxizL2qv

{
"text_tsd":""
}

Hello @mjpuser - please see the following set of commands where I try to reproduce this. The object appears to be indexed correctly in Solr. I recommend double-checking that you are saving the object with the application/json content type. If you are unable to resolve this issue in your environment, please file an issue in the riak-nodejs-client repository and I'll take it from there.

Create search index in Riak using default schema:

$ curl -4vvv -XPUT localhost:8098/search/index/lrb-test
*   Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 8098 (#0)
> PUT /search/index/lrb-test HTTP/1.1
> Host: localhost:8098
> User-Agent: curl/7.48.0
> Accept: */*

< Date: Mon, 16 May 2016 18:20:48 GMT
< Content-Type: application/json
< Content-Length: 0

Verify creation of lrb-test index:

$ curl -4vvv localhost:8098/search/index
*   Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 8098 (#0)

[{"name":"lrb-test","n_val":3,"schema":"_yz_default"}]

Create lrb-test-type and associate with lrb-test index:

$ bin/riak-admin bucket-type create lrb-test-type '{"props":{"search_index":"lrb-test"}}'
lrb-test-type created

$ bin/riak-admin bucket-type activate lrb-test-type
lrb-test-type has been activated

Verify lrb-test-type properties:

$ curl -4vvv localhost:8098/types/lrb-test-type/props|jsonpp
*   Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 8098 (#0)

Save JSON object and have Riak generate key:

$ curl -4vvv -XPOST -H 'Content-Type: application/json' localhost:8098/types/lrb-test-type/buckets/lrb-test-bucket/keys -d '{"test_tsd":""}'
Note: Unnecessary use of -X or --request, POST is already inferred.
