search

Added in 1.0.0

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.

To handle larger result sets, you have to either create a cursor by providing a value to the scroll option or, if you sort the results, by using the Elasticsearch search_after command.


Query Syntax

HTTP

URL: http://kuzzle:7512/<index>/<collection>/_search[?from=<int>][&size=<int>][&scroll=<time to live>][&includeTrash=<boolean>]
Method: POST  
Body:
{
  "query": {
    // ...
  },
  "aggregations": {
    // ...
  },
  "sort": [
    // ...
  ]
}

Other protocols

{
  "index": "<index>",
  "collection": "<collection>",
  "controller": "document",
  "action": "search",
  "body": {
    "query": {
      // ...
    },
    "aggregations": {
      // ...
    },
    "sort": [
      // ...
    ]
  },

  // optional:
  "from": <starting offset>,
  "size": <page size>,
  "scroll": "<scroll duration>",
  "includeTrash": <boolean>
}

Arguments

  • collection: collection name
  • index: index name

Optional:

  • from: paginates search results by defining the offset from the first result you want to fetch. Usually used with the size argument
  • includeTrash: if true, include documents in the trashcan
  • scroll: creates a forward-only result cursor. This option must be set with a time duration, at the end of which the cursor is destroyed. If set, a cursor identifier named scrollId is returned in the results. This cursor can then be moved forward using the scroll API action
  • size: set the maximum number of documents returned per result page

Body properties

Optional:

An empty body matches all documents in the queried collection.


Response

Returns a paginated search result set, with the following properties:

  • aggregations: provides aggregation information. Present only if an aggregations object has been provided in the search body
  • hits: array of found documents. Each document has the following properties:
    • _id: document unique identifier
    • _score: relevance score
    • _source: new document content
  • scrollId: identifier to the next page of result. Present only if the scroll argument has been set
  • total: total number of found documents. Can be greater than the number of documents in a result page, meaning that other matches than the one retrieved are available
