Hi,

Say I have a database of car models containing brand and model

| Brand | Model |
| --- | --- |
| Foo | Bar |
| Foo | Baz |

So if I search for a `Foo Bar` I want only the first document to match. If I search for just `Foo` both documents above must be returned. Each field must be fuzzy and boosted.

- The `multi_match` `best_fields` query will not work because with `AND` operator it will all terms must be present int a single field. With `OR` operator it will return document even if only single field matches when two are requested.
- Copying fields into an "all" field will not work because individual fields cannot be boosted
- The `multi_match` `cross_fields` query will not work because neither fuzziness, nor boosting are supported.
- `combined_fields` does not support fuzziness

So what are my options?

Thanks in advance.

@Tim6

Have you tried something with [Query String query](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html#query-dsl-query-string-query)?

You can use copyto in mapping to copy both brand and model to a new field and use the new field in your match query with and operator. However with fuzziness bar might also match baz since the fuzziness corrects bar to baz.
