What does a search engine indexer do

Search engines use proprietary algorithms to index and correlate data, so every search engine has its own approach to finding what you're trying to find. Its results may be based on where you're located, what else you've searched for, and what results were preferred by other users searching for the same thing, for example. The engine might assign a weight to each entry, with increasing values assigned to words as they appear near the top of the document, in sub-headings, in links, in the meta tags or in the title of the page. Each commercial search engine has a different formula for assigning weight to the words in its index.

1 Answer 1. At its core, a search engine index is simply an index that supports full text search.

Crawling is the process by which search engines discover updated content on the web, such as new sites or pages, changes to existing sites, and dead links.

Search engines don’t store all the information found on a page in their index but they keep things like: when it was created / updated, title and description of the page, type of content, associated keywords, incoming and outgoing links and a lot of other parameters that are needed by their algorithms. Early search engines held an index of a few hundred thousand pages and documents, and received maybe one or two thousand inquiries each day. Today, a top search engine will index hundreds of millions of pages, and respond to tens of millions of queries per day. How to access a search engine. For users, a search engine is accessed through a browser on their computer, smartphone, tablet, or another device. Today, most new browsers use an omnibox, which is a text box at the top of the browser. The omnibox allows users to type in a URL or a search query.
