Struct elastic_responses::search::SearchResponse

pub struct SearchResponse<T> { /* fields omitted */ }

Response for a search request.

This is the main struct of the crate, provides access to the hits and aggs iterators.

Aggregations

Aggregations currently have the following limitations:

• Only metric aggregations nested in buckets are supported
• Only Simple Metric Aggregations like avg, min, max, sum and Stats Aggregations are supported

Examples

Iterate over the hits in a search response:

let response: SearchResponse<Value> = do_request();

// Iterate over hits. Could also use `documents`
for hit in response.hits() {
    let score = hit.score().unwrap_or(f32::default());
    let doc = hit.document();

    println!("score: {}", score);
    println!("doc: {:?}", doc);
}

Methods

impl<T> SearchResponse<T>

pub fn took(&self) -> u64

Time in milliseconds it took for Elasticsearch to process the request.

pub fn timed_out(&self) -> bool

Whether or not the request timed out before completing.

pub fn shards(&self) -> &Shards

Shards metadata for the request.

pub fn status(&self) -> Option<u16>

A http status associated with the response.

pub fn total(&self) -> u64

The total number of documents that matched the search query.

pub fn max_score(&self) -> Option<f32>

The max score for documents that matched the search query.

Important traits for Hits<'a, T>

impl<'a, T: 'a> Iterator for Hits<'a, T> type Item = &'a Hit<T>;

pub fn hits(&self) -> Hits<T>

Iterate over the hits matched by the search query.

Important traits for IntoHits<T>

impl<T> Iterator for IntoHits<T> type Item = Hit<T>;

pub fn into_hits(self) -> IntoHits<T>

Convert the response into an iterator that consumes the hits.

Important traits for Documents<'a, T>

impl<'a, T: 'a> Iterator for Documents<'a, T> type Item = &'a T;

pub fn documents(&self) -> Documents<T>

Iterate over the documents matched by the search query.

This iterator emits just the _source field for the returned hits.

Important traits for IntoDocuments<T>

impl<T> Iterator for IntoDocuments<T> type Item = T;

pub fn into_documents(self) -> IntoDocuments<T>

Convert the response into an iterator that consumes the documents.

Important traits for Aggs<'a>

impl<'a> Iterator for Aggs<'a> type Item = BTreeMap<Cow<'a, str>, &'a Value>;

pub fn aggs(&self) -> Aggs

Iterate over the aggregations in the response.

This Iterator transforms the tree-like JSON object into a row/table based format for use with standard iterator adaptors.

pub fn aggs_raw(&self) -> Option<&Value>

Get a reference to the raw aggregation value.
