Documentation

Documentation for the library is available on docs.rs

Quick start

```rust use elasticsearch_dsl::*;

fn main() { let query = Search::new() .source(false) .stats("statistics") .from(0) .size(30) .query( Query::bool() .must(Query::multimatch( ["title", "description"], "you know, for search", )) .filter(Query::terms("tags", ["elasticsearch"])) .should(Query::term("verified", true).boost(10)), ) .aggregate( "countryids", Aggregation::terms("countryid") .aggregate("catalogids", Aggregation::terms("catalogid")) .aggregate("companyids", Aggregation::terms("companyid")) .aggregate( "top1", Aggregation::tophits() .size(1) .sort(FieldSort::ascending("userid")), ), ) .rescore(Rescore::new(Query::term("field", 1)).queryweight(1.2)); } ```
