Indexing has been deprecated

[Kenwwww]

why index has been deprecated？ which means only regex allowed？ Is it because the embedding effect is not good?

[omni-front]

The deprecation likely refers to a configuration or API change where indexing is replaced by regex for document retrieval.

retrieval:
  method: "regex"
  # Further regex configuration if applicable

Regex may provide more flexibility in matching patterns directly rather than relying on pre-processed index structures.
