Description
How to repro
- Unit test `testIndexMultiplePredictionValuesUsingValueIndex` - link
Steps:
1. Create multiple indexes with prediction value `[[CBLQueryFunction predictionUsingModel: input: ] property: ]`
2. Query both prediction values ``[[CBLQueryFunction predictionUsingModel: input: ] property: ]``
3. Query explain shows it scans the full table instead of search both the indexes.
Expected
SELECT fl_result(prediction('AggregateModel', dict_of('numbers', fl_value(_doc.body, 'numbers')), '.sum')) AS "s", fl_result(prediction('AggregateModel', dict_of('numbers', fl_value(_doc.body, 'numbers')), '.avg')) AS "a" FROM kv_default AS _doc WHERE (prediction('AggregateModel', dict_of('numbers', fl_value(_doc.body, 'numbers')), '.sum') <= 15 OR prediction('AggregateModel', dict_of('numbers', fl_value(_doc.body, 'numbers')), '.avg') = 8) AND (_doc.flags & 1 = 0)
