You can implement a fast, client-side search feature in your Markdown-based knowledge base without using heavy JavaScript frameworks.
Steps include creating a search index in JSON format, adding a search input in HTML, and using vanilla JS to load and search the index as the user types.
Pros of this approach include lightweight, instant client-side search, no external libraries required, and simplicity to extend. Cons include pagination for large knowledge bases and the need to regenerate search.json when content changes.
Overall, this method of adding search functionality to a Markdown knowledge base is efficient, framework-free, and easy to maintain.
