Refactor OpenSearch Relevance Functions out of Core #2019

MitchellGale · 2023-08-22T23:54:50Z

Description

Moving Relevance-based search functions out of core module and into opensearch module.
This only affects the Function Resolver.

Out of Scope:

OpenSearchFunction resolver was not moved, as the score tracking is needed in the analyzer and optimizer.
Parser
Analyzer and its sub-components
LogicalPlan or optimizer
Design for refactoring the analyzer and creating an OpenSearch analyzer: Added design for core refactor Bit-Quill/opensearch-project-sql#331

Issues Resolved

Partially fixes #811

Internal review: Bit-Quill#338

Check List

New functionality includes testing.
- All tests pass, including unit test, integration test and doctest
New functionality has been documented.
- New functionality has javadoc added
- New functionality has user manual doc added
