 First, you need to address some challenges before diving into RAG details. These models, trained on vast text data, can produce relevant and correct responses. But, like any data source, their output can be inaccurate, incomplete, or misleading due to various factors.
 
-- **Out of date sources:** The data used to train the model may be outdated and no longer accurate.
+- **Out-of-date sources:** The data used to train the model may be outdated and no longer accurate.
 - **Wrong or inaccurate information:** The sources used to train the model may contain incorrect or misleading information, like fake news or biased opinions.
 - **Non-authoritative sources:** The model may not be able to distinguish between authoritative and non-authoritative sources in its training data, leading to unreliable information.
 
-This makes it difficult to tell if an information generated by an LLM is correct or not. This is where RAG comes in.

This can be done using keyword search, full-text search, or more advanced techniques like semantic search or vector search that may need specific indexing. We'll cover advanced search techniques in a future lesson.
