Retrieval Models

Retrieval models are algorithms used by search engines to find and rank the most relevant information in response to a user’s query. They analyze the query and compare it to a large database of documents or data, measuring how well each matches the search intent. The goal is to present the most useful results quickly. These models use techniques like keyword matching, understanding context, and ranking signals to prioritize information that best answers the question or meets the user’s needs. Essentially, they act as sophisticated filters to deliver accurate and relevant search results.
