An index is a general, ordered directory that can be searched, similar to a reference work. The Google index is thus understood to be the entirety of the content or web pages on the Internet crawled and stored by Google. The search engine results, SERPs for short, are therefore exclusively filled with content or web pages from the Google index. If a page is not in the index, it cannot be found in the search results.
How the (Google) Index works?
Unlike a reference book or encyclopedia, the Google index is highly dynamic. By adding and removing web pages, the index is always “in motion”. By jumping from link to link, the crawler captures new content and associated pages every day. Certain ranking factors are taken into account and superimposed on the index, so that it is not only sorted alphabetically, but also displays a new set of web pages depending on the search query.

This information is collected and processed according to certain criteria. For example, certain contents are assigned on the basis of keywords and vice versa.
