[FEATURE] Add the ability to provide additional field definitions to the SEMANTIC_SEARCH use case. #1188
Description
Is your feature request related to a problem?
No
What solution would you like?
The semantic search template https://github.com/opensearch-project/flow-framework/blob/2d36058884e729352dc0504ef6bc500cff08a0c1/src/main/resources/substitutionTemplates/semantic-search-template.json hard-codes the index settings.
- I like the simplification, and for people that are doing only vector-based semantic search this will help
- But, if I want additional fields for any reason, or tighter control over the field definition, I can't do that.
Most people doing semantic search will have other fields. The flow framework should support something like
"create_index.additional_field_definitions": Dict[str: str]
The additional fields should be added during index creation.
What alternatives have you considered?
It is possible to add the additional fields after the index is created, but that reduces the simplicity provided by the templated workflows
Do you have any additional context?
NA
