bors[bot] 414b3fae89 Merge #3571 ... 3571: Introduce two filters to select documents with `null` and empty fields r=irevoire a=Kerollmops # Pull Request ## Related issue This PR implements the `X IS NULL`, `X IS NOT NULL`, `X IS EMPTY`, `X IS NOT EMPTY` filters that [this comment](https://github.com/meilisearch/product/discussions/539#discussioncomment-5115884) is describing in a very detailed manner. ## What does this PR do? ### `IS NULL` and `IS NOT NULL` This PR will be exposed as a prototype for now. Below is the copy/pasted version of a spec that defines this filter. - `IS NULL` matches fields that `EXISTS` AND `= IS NULL` - `IS NOT NULL` matches fields that `NOT EXISTS` OR `!= IS NULL` 1. `{"name": "A", "price": null}` 2. `{"name": "A", "price": 10}` 3. `{"name": "A"}` `price IS NULL` would match 1 `price IS NOT NULL` or `NOT price IS NULL` would match 2,3 `price EXISTS` would match 1, 2 `price NOT EXISTS` or `NOT price EXISTS` would match 3 common query : `(price EXISTS) AND (price IS NOT NULL)` would match 2 ### `IS EMPTY` and `IS NOT EMPTY` - `IS EMPTY` matches Array `[]`, Object `{}`, or String `""` fields that `EXISTS` and are empty - `IS NOT EMPTY` matches fields that `NOT EXISTS` OR are not empty. 1. `{"name": "A", "tags": null}` 2. `{"name": "A", "tags": [null]}` 3. `{"name": "A", "tags": []}` 4. `{"name": "A", "tags": ["hello","world"]}` 5. `{"name": "A", "tags": [""]}` 6. `{"name": "A"}` 7. `{"name": "A", "tags": {}}` 8. `{"name": "A", "tags": {"t1":"v1"}}` 9. `{"name": "A", "tags": {"t1":""}}` 10. `{"name": "A", "tags": ""}` `tags IS EMPTY` would match 3,7,10 `tags IS NOT EMPTY` or `NOT tags IS EMPTY` would match 1,2,4,5,6,8,9 `tags IS NULL` would match 1 `tags IS NOT NULL` or `NOT tags IS NULL` would match 2,3,4,5,6,7,8,9,10 `tags EXISTS` would match 1,2,3,4,5,7,8,9,10 `tags NOT EXISTS` or `NOT tags EXISTS` would match 6 common query : `(tags EXISTS) AND (tags IS NOT NULL) AND (tags IS NOT EMPTY)` would match 2,4,5,8,9 ## What should the reviewer do? - Check that I tested the filters - Check that I deleted the ids of the documents when deleting documents Co-authored-by: Clément Renault <clement@meilisearch.com> Co-authored-by: Kerollmops <clement@meilisearch.com>		2023-04-27 13:14:00 +00:00
