A KWIC index is a special case of a permuted index. [4] This term refers to the fact that it indexes all cyclic permutations of the headings. Books composed of many short sections with their own descriptive headings, most notably collections of manual pages, often ended with a permuted index section, allowing the reader to easily find a section by any word from its heading.
The forward index is sorted to transform it to an inverted index. The forward index is essentially a list of pairs consisting of a document and a word, collated by the document. Converting the forward index to an inverted index is only a matter of sorting the pairs by the words. In this regard, the inverted index is a word-sorted forward index.
In computer science, an inverted index (also referred to as a postings list, postings file, or inverted file) is a database index storing a mapping from content, such as words or numbers, to its locations in a table, or in a document or a set of documents (named in contrast to a forward index, which maps from documents to content).

Articles older than 90 days are automatically indexed. [1] The __NOINDEX__ magic word and the {{}} template do not work on them. Articles younger than 90 days are not indexed, unless they have been patrolled and do not have the __NOINDEX__ magic word or the {{}} template on them (or a template that transcludes the {{}} template, such as the speedy deletion templates).
Magic words (including parser functions, variables and behavior switches) are features of wiki markup that give instructions to Wikipedia's underlying MediaWiki software. For example, magic words can suppress or position the table of contents, disable indexing by external search engines, and produce output dynamically based on the current page or on user-defined conditional logic.
This template sets the __INDEX__ behavior switch, a magic word which instructs search engines to index the page. The only difference between the template and the magic word is that the template may optionally display a message.
An index differs from a word index, or concordance, in focusing on the subject of the text rather than the exact words in a text, and it differs from a table of contents because the index is ordered by subject, regardless of whether it is early or late in the book, while the listed items in a table of contents is placed in the same order as the ...
Historically, the index symbol ☞ (representing a hand with a pointing index finger) was popular for similar uses. Lists made with bullets are called bulleted lists . The HTML element name for a bulleted list is " unordered list ", because the list items are not arranged in numerical order (as they would be in a numbered list ).
