Search Data API

Overview

The data search API provides the ability to perform a free text search for data. The response is broken down by Dataflow, along with the matched Components related to the Dataflow. The Data Search API only includes Dataflows that have data loaded against them, and will only search Codes related to the Dataflow which have series loaded. The result includes the number of series that match each 'hit' within a Dataflow, where the hit is the Component that matched. For example a search for USA may match a Dataflow in the Reporting Country Dimension because there are a number of series which have Reporting Country USA. If there are also Counterpart Countries for the same Dataflow, and they too have series for USA, then this will also be a hit within the same Dataflow - although the series count for each hit may differ depending on the number of series that exist. If the match is on the Dataflow itself, and there are no hits on the individual components, then the series count will be given at the level of the Dataflow.

The searched structures are are the Codes, Dataflows and the searched facets are the Ids, Names, and Descriptions (in all languages).

  "Broad money (current LCU)","Money (current LCU)",
  "Claims on other sectors of the domestic economy (annual growth as % of broad money)"
]

Search Response

The search response is a list a list of results, each result is a match on a Dataflow and a list of Components that matched with the match text, and the number of series that exist for the matched term

Example: /ws/public/datasearch?query=population
Match on multiple Dataflows, multiple Components

{
  "time" : 28,
  "results" : [
    {
      "Dataflow": "urn:sdmx:org.sdmx.infomodel.datastructure.Dataflow=WB:WDI_HEALTH(1.0)",
      "SeriesCount": 17836,
      "Components": {
            "SERIES": {
               "SH_DYN_AIDS_FE_ZS": {
                   "Name": "Women's share of population ages 15+ living with HIV (%)",
                   "SeriesCount": 112,
                   "Match": "Women's share of population ages 15+ living with HIV (%)"
               },
               "SH_H2O_SAFE_RU_ZS": {
                   "Name": "Improved water source, rural (% of rural population with access)",
                   "SeriesCount": 190,
                   "Match": "Improved water source, rural (% of rural population with access)"
               },
               .....
      }
    }
  ]
}

Example: /ws/public/datasearch?query=WDI_HEALTH
Match on the Dataflow (no individual Components)

{
    "time": 4,
    "results": [{
        "Dataflow": "urn:sdmx:org.sdmx.infomodel.datastructure.Dataflow=WB:WDI_HEALTH(1.0)",
        "SeriesCount": 17836,
        "Components": {}
    }]
}
