I am trying to use the following Key-Filters with logical AND operation and
tokenize, but I am getting errors. Anyone know what might be wrong? Is it
possible to use tokenize with the logical AND?
Erlang: R13B04
Riak: 0.14.2
Bucket: zip
Key: 22305-0-1-3
The following does not work:
{
"inputs" : {
"bucket" : "zip",
"key_filters" : ["and", [["starts_with",
"22305-0"]], [["tokenize", "-", 4], ["between", "1", "3"]]]
},
"query" : [{
"map" : {
"keep" : true,
"language" :
"javascript",
"arg" : null,
"source" :
"function (v) { return [Riak.mapValuesJson(v)[0]]; }"
}
}
]
}
I get the following error:
{error,{error,function_clause,[{riak_client,build_exprs,[[<<\"and\">>,[[<<\"starts_with\">>,<<\"22305-0\">>]],[[<<\"tokenize\">>,<<\"-\">>,2],[<<\"between\">>,<<\"1\">>,<<\"3\">>]]],[],{riak_client,'[email protected]',<<3,171,198,76>>}]},{riak_client,build_filter,2},{riak_client,stream_list_keys,6},{riak_client,mapred_bucket_stream,7},{riak_client,mapred_bucket,6},{riak_kv_wm_mapred,process_post,2},{webmachine_resource,resource_call,3},{webmachine_resource,do,3}]}}
The following does work:
{
"inputs" : {
"bucket" : "zip",
"key_filters" : [["tokenize", "-", 4],
["between", "1", "5"]]
},
"query" : [{
"map" : {
"keep" : true,
"language" :
"javascript",
"arg" : null,
"source" :
"function (v) { return [Riak.mapValuesJson(v)[0]]; }"
}
}
]
}
