Different queries can be combined using the BooleanQuery. Tantivy comes with different types of queries and can be extended by implementing the Query, Weight, and Scorer traits.
Compose query conditions(query_parser.rs):
let custom_query = BooleanQuery::new(vec![
(
Occur::Must,
Box::new(RangeQuery::new_f64(lat, 1234.1231f64..1234.1232f64)),
),
(
Occur::Must,
Box::new(RangeQuery::new_f64(long, 4321.4312f64..4321.4313f64)),
),
(
Occur::Must,
Box::new(TermQuery::new(
Term::from_field_text(body, "denis"),
IndexRecordOption::WithFreqs,
)),
),
]); will get similar results to:
let query = query_parser
.parse_query("+lat:[1234.1231 TO 1234.1232}
+long:[4321.4312 TO 4321.4313} +body:denis")?;
