How-to guides for the semantic_text field type

These guides provide procedure descriptions and examples for common tasks when working with semantic_text fields:

• Set up and configure semantic_text fields: Learn how to configure inference endpoints, including default endpoints, Jina on EIS, ELSER on EIS, third-party models on EIS, external inference, and dedicated endpoints for ingestion and search operations.

• Ingest data with semantic_text fields: Learn how to index pre-chunked content, use copy_to and multi-fields to collect values from multiple fields, and perform updates and partial updates to optimize ingestion costs.

• Search and retrieve semantic_text fields: Learn how to query semantic_text fields, retrieve indexed chunks, return field embeddings, and highlight the most relevant fragments from search results.
