Part of #236938 ## Summary This PR adds `AST` support for the new`FUSE` parameters. ``` fuseCommand : DEV_FUSE (fuseType=identifier)? (fuseConfiguration)* ; fuseConfiguration : SCORE BY score=qualifiedName | KEY BY key=fields | GROUP BY group=qualifiedName | WITH options=mapExpression ; ``` `FUSE <fuse_method> SCORE BY <score_column> GROUP BY <group_column> KEY BY <key_columns> WITH <options>` ### Some Examples `| FUSE LINEAR # Merge results using linear combination of scores (equal weights by default)` `| FUSE LINEAR WITH { "normalizer": "minmax" } # Linear combination with min-max normalization (scales scores to 0-1 range) ` `| FUSE LINEAR WITH { "weights": { "fork1": 0.7, "fork2": 0.3 }, "normalizer": "minmax" } # Weighted linear combination: 70% lexical, 30% semantic, with min-max normalization` ### Note No tests has been added to check parameters or fields with dots, as the parser needs this [fix](elastic/elasticsearch#135901) to be merged to support them. ### Checklist - [x] [Unit or functional tests](https://www.elastic.co/guide/en/kibana/master/development-tests.html) were updated or added to match the most common scenarios
