ElasticQueryBuilder

ElasticQueryBuilder is a query builder designed to easily build ElasticSearch related DSLs.

install

```toml

Cargo.toml

[dependencies] elastic-query-builder ="0.1" ```

Futures

• Mapping
• DML Query
• Aggregation

Mapping

rust fn main() { let mut mapping = MappingBuilder::new(); mapping .add_property("title", KeywordFieldType::new()) .add_property("content", TextFieldType::new()); assert_eq!( mapping.build().to_string(), r#"{"mappings":{"properties":{"content":{"type":"text"},"title":{"type":"keyword"}}}}"# ); }

DML Query

Build Json Query

rust fn main() { let mut query = QueryBuilder::new(); query.set_query(MatchQuery::new("field", "value")); query.set_from(10); query.set_size(100); let value_json = query.build(); }

Providing Query

• bool_query
• exists_query
• geodistancequery
• matchallquery
• match_query
• multimatchquery
• nested
• range_query
• script_query
• scriptscorequery
• term_query
• terms_query
• wildcard_query

BoolQuery Example

rust fn main() { let mut query = QueryBuilder::new(); let mut bool = BoolQuery::new(); bool.add_must(MatchQuery::new("field1", "value")); bool.add_must_not(MatchQuery::new("field2", "value")); bool.add_should(MatchQuery::new("field3", "value")); query.set_query(bool); }

Nested Example

rust fn main() { let mut query = QueryBuilder::new(); let nested = NestedQuery::new("locations", MatchQuery::new("locations.country", "JP")); query.set_query(nested); }
