Indexing documents:
Once a page has been crawled, its contents can be "indexed" - stored in a giant database of documents that makes up a search engine's "index".
Ranking Results
Once the search engine has determined which results are a match for the query, the engine's algorithm (a mathematical equation commonly used for sorting) runs calculations on each of the results to determine which is most relevant to the given query.
