    "# Running Hybrid VSS Queries with Redis and OpenAI\n",
    "\n",
    "This notebook provides an introduction to using Redis as a vector database with OpenAI embeddings and running hybrid queries that combine VSS and lexical search using Redis Query and Search capability. Redis is a scalable, real-time database that can be used as a vector database when using the [RediSearch Module](https://oss.redislabs.com/redisearch/). The Redis Query and Search capability allows you to index and search for vectors in Redis. This notebook will show you how to use the Redis Query and Search to index and search for vectors created by using the OpenAI API and stored in Redis.\n",
    "\n",
    "Hybrid queries combine vector similarity with traditional Redis Query and Search filtering capabilities on GEO, NUMERIC, TAG or TEXT data simplifying application code. A common example of a hybrid query in an e-commerce use case is to find items visually similar to a given query image limited to items available in a GEO location and within a price range."

    "Before we start this project, we need to set up the following:\n",
    "\n",
    "* start a Redis database with RediSearch (redis-stack)\n",
    "* install libraries\n",
    "    * [Redis-py](https://github.com/redis/redis-py)\n",
    "* get your [OpenAI API key](https://beta.openai.com/account/api-keys)\n",
