infographic. However, search tools have been moving steadily in a more
direction as they have become more user-centred, interactive and multimodal. They are arguably also moving in a
direction with the arrival of social and personal search. Search is also available on
, though the move to the use of dedicated apps has arguably rendered search less important on mobile devices than on the web (see
Search engines help users to find material amongst the vast amount of online content. Currently, key trends point towards greater differentiation, customisation and personalisation of search.
As search becomes more personalised, the activity of searching may, ironically, become less common, as more and more relevant information flows automatically to individuals without the need for specific searches to find it.
For the foreseeable future we'll still need search engines. It's worth getting acquainted with the wide range of specialist search tools out there on the web. These are useful not only for teachers but also for students, who urgently need to develop appropriate information literacy skills to locate, navigate, evaluate and manage information online.
Key features of newer search services include those listed below. It should be noted that Google offers a range of similar features to many of those detailed here. More information can be found under

Customisation of search presentation:
It is increasingly possible to choose among different presentation formats of search results, many of which are very different from traditional, linear lists of search results. There is currently some experimentation with mind map formats, as seen on services like
Quintura for Kids
, which shows Wikipedia results as a mind map. Image search engines with interesting visual presentation formats include the Flickr-based
(see image above left) and the
Flickr Related Tag Browser
maps film and musical preferences, underpinned by Amazon 's recommendations software. Many of the search services mentioned in the previous section also work with unusual visual presentation formats; examples include
We're also just beginning to see a move towards the visual presentation of search itself (as opposed to the results of a search). For a good early example see Healthline's 3-dimensional
Human Body Maps
. Map-based search tools, such as
several that work with Wikipedia
, also fall into this category.
Customisation of search context:
It is also increasingly the case that the search context is defined in relation to the individual doing the searching, and the other people to whom that individual is connected. This approach often goes under the name of
It is typically an automated function of the major search services, notably Google, which tailors search results to individuals on the basis of information tracked or inferred about them as a result of past searches, online connections, and online activities. The result is that two individuals searching for exactly the same topic using exactly the same search terms in Google may find that they receive very different results.
A similar approach is used to determine what news items a Facebook user sees in their newsfeed.
Of course, once information is filtered through users' social networks on Facebook, Twitter and other similar services, it flows automatically to them - which partly eliminates the need for searching, because relevant information is already immediately available.
ultimate aim of social search is to obviate the need for searching at all, with search engines becoming more like prediction engines which anticipate users' needs, as seen in Google Now (see video below).
It is also possible to set up personalised search services or portals, which search only defined areas of the web, notably with
Google Custom Search
► going mobile
The major web search engines are available in mobile app versions; these include Google (incorporating Google Now), Yahoo! and Bing. As of mid-2013, Google is absolutely dominant in this market, being used for around 95% of mobile searches. However, given that smart device users have gravitated towards single-purpose apps and away from the mobile web, search is generally of lesser importance on mobile devices than on laptop and desktop devices.
It is possible to find mobile apps by:
searching within app stores such as
(for Apple iOS apps) or
(for Android apps)
searching with general-purpose search engines like Google, Yahoo!, or Bing
using specialised search services like
, which searches for mobile, desktop, browser and web apps
offers an overview of common searches while
allows comparisons between search terms.

There's no such thing as a finished wiki. Like all wikis, this one is a work in progress and there will be changes from time to time in organisation, content and links. However, don't let that stop you from
