What Is the Indexing System?

The indexing system takes the information that's been crawled, turns it into a huge repository that Google then draws on to serve the search results. It brings in what they call the fetch logs, which are actually the data that the crawler builds up. Then there's the canonicalization, which that's really where I get confused of crawling this process of going through the siteIndexing is kind of rank ordering the paging, putting them in the index.
