Request

message RpbSearchQueryReq {
  required bytes  q      =  1;
  required bytes  index  =  2;
  optional uint32 rows   =  3;
  optional uint32 start  =  4;
  optional bytes  sort   =  5;
  optional bytes  filter =  6;
  optional bytes  df     =  7;
  optional bytes  op     =  8;
  repeated bytes  fl     =  9;
  optional bytes  presort = 10;
}

Required Parameters

q - The contents of the query
index - The name of the index to search

Optional Parameters

rows - The maximum number of rows to return
start - A start offset, i.e. the number of keys to skip before returning values
sort - How the search results are to be sorted
filter - Filters search with additional query scoped to inline fields
df - Override the default_field setting in the schema file
op - and or or, to override the default_op operation setting in the schema file
fl - Return the fields limit
presort - Presort. The options are key or score

Response

The results of a search query are returned as a repeating list of 0 or more RpbSearchDocs. RpbSearchDocs themselves are composed of 0 or more key/value pairs (RpbPair) that match the given request parameters. It also returns the maximum search score and the number of results.

// RbpPair is a generic key/value pair datatype used for
// other message types
message RpbPair {
  required bytes key = 1;
  optional bytes value = 2;
}

message RpbSearchDoc {
  repeated RpbPair fields = 1;
}

message RpbSearchQueryResp {
  repeated RpbSearchDoc docs      = 1;
  optional float        max_score = 2;
  optional uint32       num_found = 3;
}

Values

docs - A list of docs that match the search request
max_score - The top score returned
num_found - Returns the total number of values matched by this search

Example
