Canonical link element. A canonical link element is an HTML element that helps webmasters prevent duplicate content issues by specifying the "canonical" or "preferred" version of a web page as part of search engine optimization.
It is described in RFC 6596, which went live in April 2012. Duplicate content issues occur when the same content is accessible from multiple URLs. For example, would be considered by search engines to be an entirely different page from even though both URLs return the same content. Another example is essentially the same (tabular) content, but sorted differently. Canonical tags can also be useful to solve www and non-www duplicate content—where two URLs, identical except that one begins with "www" and other does not, point to the same page. This particular problem can be solved by proper use of the canonical tag. According to Google, the canonical link element is not considered to be a directive, but a hint that the web crawler will "honor strongly". Examples Git Tutorials and Training. Tomasz Kowalczyk.

Popular engines focus on the full-text indexing of online, natural language documents. Media types such as video and audio and graphics are also searchable. Meta search engines reuse the indices of other services and do not store a local index, whereas cache-based search engines permanently store the index along with the corpus.
Unlike full-text indices, partial-text services restrict the depth indexed to reduce index size. Larger services typically perform indexing at a predetermined time interval due to the required time and processing costs, while agent-based search engines index in real time. Indexing The purpose of storing an index is to optimize speed and performance in finding relevant documents for a search query.
