+> Redis is not used to store embeddings anymore, but now the Vector Store in Cognitive Search is used for the embeddings. Redis is still needed to store the user conversation history (chat session). Therefore, a Redis container (ACI) can be used instead of Redis Enterprise. The user can use redis.yml in the repo to create a Redis container.

 # Purpose
-The purpose of this repo is to accelerate the deployment of a Python-based Knowledge Mining solution with OpenAI that will ingest a Knowledge Base, generate embeddings using the contents extracted, store them in a vector search engine (Redis), and use that engine to answer queries / questions specific to that Knowledge Base.
+The purpose of this repo is to accelerate the deployment of a Python-based Knowledge Mining solution with OpenAI that will ingest a Knowledge Base, generate embeddings using the contents extracted, store them in a vector search engine (Cognitive Search), and use that engine to answer queries / questions specific to that Knowledge Base.
 
 The Cognitive Search component serves to make it easier to ingest a Knowledge Base with a variety of document formats. The Cognitive Services component connected to the Search makes it possible to have an enrichment pipeline. This pipeline can generate information based on images for example, which can be included at the time of generating embeddings.

 1. Added filtering support in the Bot HTTP request API. This would be useful for things like multi-tenant demos, and filtering on docuemnts with an original source language. Use `"filter":"@field:value"` in the HTTP request e.g. `"filter":"@orig_lang:en"`.

-1. The Conversational-Chat-ReAct Agent gave a mixed bag of results. Because it has not been explicitly instructed in the prompt how many iterations it can do, sometimes it did one search in Redis (or Cognitive Search), and sometimes two searches. The first search is almost always about Sherlock Holmes, with the search string `"Sherlock Holmes country"`. If it did go for a second search iteration, then it looks for `"Volcano hotel country"`. The final answer is either `"Sherlock Holmes is a fictional character from the United Kingdom. However, I do not have information about the location of the Volcano hotel."` or, when it does 2 searches, then it gets `"The Volcano Hotel is located in Las Vegas, United States. Sherlock Holmes lived in London, England . Therefore, Sherlock Holmes did not live in the same country as the Volcano Hotel."`.
