SearchAsync #

Searches documents.

There is a limit to how many documents can be returned by a single search query. That limit is by default set at 10000 documents, and you can't get over it even with the from and size pagination options.

When processing a large number of documents (i.e. more than 1000), it is advised to paginate the results using SearchResults.Next rather than increasing the size parameter.

Arguments #

public async Task<SearchResults> SearchAsync(
    string index, 
    string collection, 
    JObject query,
    SearchOptions options = null);

Argument	Type	Description
`index`	string	Index name
`collection`	string	Collection name
`query`	JObject	JObject representing the search query
`options`	SearchOptions	An instance of SearchOptions class

query #

A JObject representing the query. Query can have the following root properties:

query: the search query itself, using the ElasticSearch Query DSL syntax.
aggregations: control how the search results should be aggregated
sort: contains a list of fields, used to sort search results, in order of importance.

An empty body matches all documents in the queried collection.

Return #

Returns a SearchResults instance.

Exceptions #

Throws a KuzzleException if there is an error. See how to handle errors.

Usage #

try {
  for (int i = 0; i < 5; i++) {
    await kuzzle.Document.CreateAsync(
      "nyc-open-data",
      "yellow-taxi",
      JObject.Parse(@"{
        ""category"": ""suv""
      }"));
  }
  for (int i = 5; i < 15; i++) {
    await kuzzle.Document.CreateAsync(
      "nyc-open-data",
      "yellow-taxi",
      JObject.Parse(@"{
        ""category"": ""limousine""
      }"));
  }
  await kuzzle.Collection.RefreshAsync("nyc-open-data", "yellow-taxi");
  SearchOptions options = new SearchOptions();
  options.From = 0;
  options.Size = 2;
  SearchResults result = await kuzzle.Document.SearchAsync(
    "nyc-open-data",
    "yellow-taxi",
    JObject.Parse(@"{
      ""query"": {
        ""match"": {
          ""category"": ""suv""
        }
      }
    }"),
    options);
  Console.WriteLine($"Successfully retrieved {result.Total} documents");
} catch (KuzzleException e) {
  Console.Error.WriteLine(e);
