Fix Plan

To update the Exa retriever to use the recommended auto search type by default, follow these steps:

• Update the ExaSearchRetriever class to set the default type to auto:

class ExaSearchRetriever:
    def __init__(self, ...):
        self.type = 'auto'  # Update default type to 'auto'
        ...

• Reorder the type Literal in ExaSearchResults tool to put auto first:

from typing import Literal

class ExaSearchResults:
    type: Literal['auto', 'neural']  # Reorder to put 'auto' first
    ...

• Update the description to mention Exa is a web search API built for AI:

class ExaSearchRetriever:
    def __init__(self, ...):
        self.description = 'Exa is a web search API built for AI'
        ...

Verification

To verify the fix, create a new instance of ExaSearchRetriever and check that the default type is set to auto:

retriever = ExaSearchRetriever()
print(retriever.type)  # Should print 'auto'

Extra Tips

• Make sure to update the documentation to reflect the new default search type.
• Test the ExaSearchRetriever class with different search queries to ensure the auto type is working as expected.
