Let’s see how this works.<\/p>\n

\n

<\/a> \ud83c\udfe8 A Simple Real-World Example <\/h2>\n

Suppose your company’s travel policy says:<\/p>\n

\n

Employees can claim hotel expenses up to \u20b95,000 per night when traveling for business.<\/p>\n<\/blockquote>\n

An employee asks:<\/p>\n

\n

“What is the hotel reimbursement limit?”<\/strong><\/p>\n<\/blockquote>\n

A RAG application can:<\/p>\n

    \n
  1. Search the company’s travel policy.<\/li>\n
  2. Find the relevant information.<\/li>\n
  3. Provide that information to the AI.<\/li>\n
  4. Generate an answer.<\/li>\n<\/ol>\n

    The AI can then respond:<\/p>\n

    \n

    “According to the travel policy, employees can claim hotel expenses up to \u20b95,000 per night.”<\/strong><\/p>\n<\/blockquote>\n

    Notice what happened?<\/p>\n

    The AI didn’t need to already know your company’s travel policy.<\/p>\n

    The application retrieved the relevant information first<\/strong>.<\/p>\n

    That’s the basic idea behind RAG.<\/p>\n

    \n

    <\/a> \ud83d\udd0d How Does RAG Actually Work? <\/h2>\n

    Let’s break it down into a few simple steps.<\/p>\n

    Don’t worry \u2014 we’ll keep the technical jargon to a minimum.<\/p>\n

    A basic RAG application can be understood in two stages<\/strong>:<\/p>\n

      \n
    1. Prepare the knowledge<\/strong><\/li>\n
    2. Answer the user’s question<\/strong><\/li>\n<\/ol>\n

      Let’s look at both.<\/p>\n

      \n

      <\/a> \ud83d\udcda Stage 1: Prepare the Knowledge <\/h2>\n

      Before users can ask questions, we need to prepare the documents so that relevant information can be found quickly.<\/p>\n

      <\/a> \ud83d\udcc4 Step 1: Collect Your Documents <\/h3>\n

      Your knowledge could come from many places:<\/p>\n
