Embeddings issue in the generate_user_intent action for Topical Rails use case

[roldanjorge]

Hi, I am currently using nemoguardrails==0.11.0. I am using Topical rails and I am having issues originating from the generate_user_intent method in the generation.py file.

The issue is that when the method self.user_message_index.search(...) is called it always returns the same embedding corresponding to the same user input in my colang file. This embedding is stored in the results and eventually used as part of the examples that are an message to the GENERATE_USER_INTENT prompt . Instead of returning the same embedding, I am expecting more embeddings from my colang file similar to the user message. This issue is causing significant performance drops because the example used in the prompt is always the same.
