Returns a join that pairs each element from the first collection with a group of matching elements from the second collection. The list of matches is added to each result as an additional property. If measureKey is specified, each match has the value of its join measure attached. Join measures are produced when withinDistance or maxDifference filters are used as the join condition.
| Usage | Returns | ee.Join.saveAll(matchesKey, ordering, ascending, measureKey, outer) | Join |
| Argument | Type | Details | matchesKey | String | The property name used to save the matches list. |
ordering | String, default: null | The property on which to sort the matches list. |
ascending | Boolean, default: true | Whether the ordering is ascending. |

[null,null,["Last updated 2023-10-06 UTC."],[],["The `ee.Join.saveAll` function creates a join between two collections, pairing each element from the first with matching elements from the second. Matched elements are stored as a list under a specified `matchesKey`. Optionally, this list can be sorted by a given property (`ordering`) in ascending or descending order. If a join condition with distance or difference measures is used, the measurement values are attached using the `measureKey`. If `outer` is set to true elements from first collection without matches will be included in the result.\n"]]
