The easiest way is to let it do web searches with a tool former/plugin framework. For specifically knowledge you want it to be able to recall (like knowledge base articles or blog posts) vector database embeddings are best. For knowledge you want it to operationalize, like being able to program in a new language the last resort is finetuning but this is not easy, requires massive amounts of high quality data, and is not generally effective for things which do not have a large amount of data to fine tune on (tens of thousands of pages worth of content).
