How AI Search Architecture Works

The Core Components

Modern AI search systems use a complex architecture that brings together many different technologies:

1. Retrieval-Augmented Generation (RAG) is the basic structure that combines pre-trained language models with outside text databases to make outputs that are more accurate and relevant to the situation.
2. Large Language Models (LLMs) are advanced AI models that use deep learning methods and usually have neural networks with many layers and many parameters.
3. Semantic Search Capabilities: Systems that don’t just look at keywords but also understand and process user queries based on their intent and the context in which they are asked.
4. Vector databases are storage systems that can quickly identify the vectors that are most relevant to each query.

The RAG Process: Step-by-Step Algorithm

This is how AI systems like Claude and ChatGPT read sources and come up with results:

Step 1: Processing and understanding the Query

The system breaks down the user’s query into its parts and uses semantic understanding of keywords to figure out what the user wants, how far they want to go, and what limitations they have.

Step 2: Document Retrieval

Using dense retrieval mechanisms, the system looks through indexed documents and external knowledge bases to identify information that is useful.

Step 3: Embedding Generation

The system turns the query into an embedding and then compares it to document embeddings to identify chunks whose embeddings are most similar using methods like cosine similarity and Euclidean distance.

Step 4: Context Augmentation

The system conditions the language model’s generation process on the documents it finds, which lets the model use information from outside sources in its answers.

Step 5: Response Generation

The generator makes an output based on the enhanced prompt by combining the user input with the data that was found.

Step 6: Source Attribution

AI-enhanced search tools automatically supply citations and links to original sources, which opens up new ways to attract more visitors to websites.

How AI Systems Crawl and Index Content

Modern Web Crawling Technologies

AI algorithms are getting better at figuring out what users want by using machine learning to help crawlers adapt to new patterns and changes on the web. Predictive analysis can also tell you which websites are likely to update their content often.

Key Crawling Mechanisms

1. Semantic Analysis: Natural Language Processing (NLP) and semantic analysis allow AI-powered crawlers to understand the meaning behind the content they index, interpreting context and nuances of language
2. Pattern Recognition: Machine learning excels at recognizing patterns in data, identifying which parts of a website are most likely to contain valuable information while ignoring boilerplate content
3. Dynamic Resource Allocation: ML helps in dynamically allocating crawl budget by determining the value of crawling each page, with high-value pages crawled more frequently

AI Crawler Growth and Impact

The AI crawler landscape saw significant growth between May 2024 and May 2025, with GPTBot (from OpenAI) surging from 5% to 30% share, and AI and search crawler traffic growing by 18% overall

The Source Processing Pipeline

Document Analysis and Chunking

AI systems process sources through sophisticated document analysis:

1. Content Segmentation: Choosing the right chunking strategy depends on the content you are dealing with and the application you are generating responses for
2. Semantic Representation: The process involves directly improving the semantic representations that power the retriever
3. Quality Assessment: AI techniques suggest search terms, retrieve most relevant documents, rank them, and visualize their content, though AI is less effective in formulating search queries but can reduce time and cost of sifting through patents

Ranking and Relevance Algorithms

Google AI uses machine learning algorithms like RankNet relevance of keywords, backlinks, user behavior, and trustworthiness.
