Hi everyone,

Is there a way to combine chat engine ("condense_plus_context" mode) functionality with auto-retrieval (OpenAIAssistantAgent/OpenAIAgent)? In the examples and tutorials it always seems like either one or the other. The closest thing seems to be chat engine with chat_mode="openai", but I can't see a way to plug in my custom auto_retrieve_tool.

Hey guys, I have a question regarding document metadata - in all examples/tutorials metadata is presented as a list of simple {key}:{value} string pairs. But what about more complex cases, let's say:

1. value is a list of strings
2. value is a dict
3. value is a list of dicts

Are there ways to represent such metadata in LlamaIndex Documents to make sure it is understood/handled properly by the embedder and LLM?
