Search engine indexer software

This is a much faster approach than listing all known documents against all relevant keywords and characters.

Below is a very basic example which illustrates the concept of inverted indexing. In the example you can see that each keyword or token is associated with a row of documents in which that element was identified. This example uses URLs but these might be document IDs instead depending on how the search engine is structured. In addition to indexing pages, search engines may also store a highly compressed text-only version of a document including all HTML and metadata.

The value passed by each individual link is based on the number and value of links which point to the page with the link. PageRank is just one of the many signals used within the large Google ranking algorithm. An approximation of the PageRank values were initially provided by Google but they are no longer publicly visible. While PageRank is a Google term, all commercial search engines calculate and use an equivalent link equity metric.

To me it is obvious that it is not just a regular table with an index and a descrption column Actually in it's simplest form that's about it. This would depend on your project requirements and have you to do everything yourself or can you use tools? A database would, as Yannis says, be the most simple form. Some full text search engine Apache Lucene would be smarter and worth to look at if you need to do it yourself.
