The current MoreLikeThisQueryBuilder validation checks for existence of at
least one `like` text or item. This is hard to check in setters, so this PR
tries to change the construction of the query so that we can do these checks
already at construction time.
Changing to using arrays for fieldnames, likeTexts, likeItems, unlikeTexts
and unlikeItems. `likeTexts` and/or `likeItems` need to be specified at
construction time to validate we have at least one item there.
Relates to #10217
Not the neatest implementation in the world. Maybe we should consider changing the builders so it is a single builder for sort and a single builder for rescore instead of a list of builders for each?
This commit removes all the opaque bytes for extra_source and template_source.
Instead source and extra_source etc. are represented as SearchSourceBuilder which can
in-place be modified and is updated with the content of the request parameters.
Template Source is parsed and evaluated which in-turn replaces the actual source.
Refactor the function_score query so it can be parsed on the coordinating node, split parse into fromXContent and toQuery, make FunctionScoreQueryBuilder Writeable.
Closes#13653
Given that we are moving to parsing queries on the coordinating node, the index name is not relevant anymore in QueryParseContext, as the parsing phase cannot be related to any specific index. On the contrary, the QueryShardContext is the one that holds mappings etc. and the index name too, as the lucene query creation happens on the data node and can still be related with the index that it happens against.
Changes are mainly around tests that were expecting the index name, moved to using QueryShardException in some of them, removed the index name elsewhere.
Closes#13631
Moving validation from validate() to constructors and setters for the
following query builders:
* GeoDistanceQueryBuilder
* GeoDistanceRangeQueryBuilder
* GeoPolygonQueryBuilder
* GeoShapeQueryBuilder
* GeohashCellQuery
* TermsQueryBuilder
Relates to #10217
This parser prototype allows to decleratively define parsers for XContent
instead of writing messy and error prone while loops. It encapsulates all the error handling logic
and only even tries to parse if the token types match the declaration.
