O'Reilly Answers (from O'Reilly homepage)
O'Reilly has introduced a new search feature that allows you to enter a natural language query into a search box. Natural language queries, unlike key terms, take the form of a question. For example, instead of typing: Python AND datasets, you could type: How can I use Python to pull data and analyze large datasets. The result comes only from the O'Reilly database of books, ebooks, videos, audiobooks, etc. For that reason, queries on topics that are covered in the O'Reilly database have a better chance of success (e.g., business, technology.)
To access, click the Answers button in the top navigation bar.

The result will include an article on your topic, recommended O'Reilly sources from which the article is generated, such as ebooks, videos, etc., a "more on this topic" section with recommended O'Reilly resources, as well as related questions to explore that might help you to dig deeper into the topic.

You may also use O'Reilly Answers while you are reading an ebook. Simply click the sparkles icon to the right of the ebook display, and enter your query.

After entering your question, an article will appear. Citations will be provided for the information; simply click the number to see the citation so that you can explore the source material. Beneath the article, there are related questions to explore, the list of sources used in the article, and more resources on the topic.

According to O'Reilly, your interactions with this tool will not be used to train the AI model. For more information, see O'Reilly's documentation:
