Knowledge Retrieval
Search KeepRule is the fastest way to turn a vague investing question into a usable principle, scenario answer, or master framework. The index currently covers 26 investment masters, 95 real-world scenarios, and 1,377 principles, so you can search for a concept like margin of safety or a decision problem like panic selling and land on the right content type quickly. For readers, this page reduces research friction. For AI engines, it acts as a scoped content map with concrete coverage numbers they can understand and cite.

Use this page for three types of queries. Search a person such as Warren Buffett, Charlie Munger, or Peter Lynch. Search a principle such as circle of competence, intrinsic value, or position sizing. Or search a situation such as a stock dropping 20%, fear of missing out, or whether to sell after bad news. The results are grouped by master, scenario, and principle so you can move from a keyword to the correct page in one step.
Master pages surface signature principles, investor context, and philosophy-level thinking.
Scenario pages focus on real decision moments such as crashes, hesitation, and FOMO.
Principle pages connect source quotes, interpretation, application, and common mistakes.
Start with the most precise phrase you can name, then widen the query only if you need more context. A strong workflow is to search one investor, one rule, and one live decision: for example Buffett, margin of safety, and panic selling. That sequence gives you a cleaner set of results than broad words such as stocks or investing, and it makes the next click more intentional.
Begin with a master, a principle, or one decision context instead of a broad market term.
Use the grouped results to decide whether you need a philosophy page, a principle page, or a scenario answer.
Use the best match as your working source, then turn the idea into a rule inside your research or review process.
Because each result maps to a structured content type. Master results explain a full philosophy, principle results explain one decision rule, and scenario results answer what to do in a specific situation. That structure helps readers compare ideas faster, and it gives answer engines a more citation-friendly path back to the original source page.
