== Purpose ==
A ''search function'' allows to generate a subset out of a big number of items on ground of a user defined pattern.  The function is essential to find matching items in case of a extended list or if the position of target(s) is unknown, as well as when bulk operations should be executed to a subset. A search operation interrupts the 'predefined workflow' and bypass core functions to a user-defined data set.
 
Supplemental to search is the ''filter function'' which rather reduces a given number of items than generating an output.
 
== Guidelines ==
* Make the search result persistent. Users must not need to research after selecting or referencing an item.
* Consider to allow iterative search on result lists.
* Do not inherit artificial intelligence from users. Search operations have always be clear and comprehensible to users.
* Follow the guidelines on [[Projects/Usability/HIG/ProgressIndicator|delayed operations]] if the search takes longer.
* Provide paging/scrolling of results.
* Provide auto complete feature to the input based on previous operations.
* Start the search process via button or when the user pressed enter.
* Show the search pattern at the header of the result list (e.g. "Search results for: <Hello World>")
* Show hints on how to use the search effectively.
* Do case insensitive search, unless its important.
* Make the search box large enough to show at least 20 characters (at the moment: KRunner & Kicker = 24, Konqueror = 54, KCM = 33, cf. ).
* Run a combined AND search when two words have been entered unless the term is quoted (e.g. Hello World vs "Hello World")
 
== Appearance ==
* Search input consists of an icon, a line input to enter the search pattern, and a button to start the search. (VDG could make a proposal how it looks nice)
* ''Placement''
** Start search at the upper right area of your dialog (KCM and web style).
** Start search at the lower left area of your dialog (Kicker and Konqueror style).
** Show search centered in the upper area of your dialog (Dolphin and KRunner style).
* ''To show or not to show:''
** Always show search input. Do not hide the availability from users.
** Show input control only when users start the search.
** Hide the control in case the search is not the primary function of the app, but show a small button which indicates clearly the availability of the function.
** Active the control and focus it on Ctrl+F or when user clicks the icon.
** Do not use search icon anywhere else.
* ''How to present results'' (Depends on use case?)
** Highlight search results (KCM mode).
** Hide non-matching results (Kicker mode).
** Generate a new list that matches the search pattern  (KRunner mode).
