A search is a means of accessing information quickly. If an amount of data is too large for users to find something just by scanning through it, you should consider providing a search function.
Use a search field (sap.m.SearchField) if you want to enable users to enter text to search for information. The search field is also the control of choice for filtering down a given amount of information.
When suggestions are turned on, the suggestion list displays differently depending on the device type.

Clicking or tapping the search field opens a new full screen dialog in which items can be selected from a list of suggestions.
SAP Fiori comes with two different search types.
- The manual search is triggered explicitly after the user enters text in the search field and clicks or taps the Search button or presses the Enter key.
- The live search (also known as “incremental search” or “search-as-you-type”) is triggered by each character that the user enters or deletes. There is a default delay of 400 ms before sending the search data to the back end. This ensures better performance and optimizes user experience.
Queries that are entered are used to search the back-end data for term matches (not case-sensitive). While a live search uses a “contains” approach, a manual search uses a “starts with” approach. “Contains” means that the result needs to match the query only partly to be a valid result. “Starts with” means that full terms of the result need to start with the entered query to be visualized.
The search input field (or search box) consists of two parts:
- The text input, which is left-aligned. Initially, the field shows a placeholder (Search). As soon as the user enters a character, this prompt text disappears. It appears again if the user deletes the entry.
- If a manual search is to be implemented, a search button with a magnifier icon is placed on the right side of this input control. The user clicks or taps this button to trigger the search. In live searches, the magnifier icon is also placed here, but it functions more like an additional indicator to signify that this is a search input field. It also functions as an explicit search button if the user wants to search again for a query that has already been entered.
All item attributes defined by the app development team are searched. When the results are displayed, the items found do not necessarily have to show the attribute through which the item was found. The results are displayed in the same list that contained the original item set. Initial grouping and the order of the list are not affected by the search.
Behavior and Interaction
Entering a Search Term
Search terms can be entered easily into the input field. The search box then displays all full-text search terms. There is no line break and no truncation if the query is longer than the input field. Results might also be displayed that do not match the query in their title or subtitle. This might be because details can also be searched for. The user can see the matching terms in the specific details section.
Deleting a Search Term
The user can click or tap the “X” icon ( ) button to remove the text from the field. In the case of the live search, this also resets the search. In a manual search, deleting the search term and then triggering the search resets the search results.
If the Refresh button is available, the user can update the list without triggering a new search. This is usually needed when backend data changes quickly and often.
If the currently selected item is no longer available after the list has been refreshed, the next item in the line is selected. If no next item is available, the first item in the line should be selected next.
Search field with refresh
On touch devices, the Refresh icon is not visible in the search field. In this case, Pull Down to Refresh is used instead. The Pull Down to Refresh arrow icon is animated and spins to signal that the user should release it.
Pull to Refresh
The following methods are important.
For the live search:
- attachLiveChange(oData?, fnFunction, oListener?) Attach event handler
fnFunctionto the ‘liveChange’ event of this
- detachLiveChange(fnFunction, oListener) Detach event handler
fnFunctionfrom the ‘liveChange’ event of this
- fireLiveChange(mArguments?) Fire event liveChange to attached listeners.
For the manual search:
- attachSearch(oData?, fnFunction, oListener?) Attach event handler
fnFunctionto the ‘search’ event of this
- detachSearch(fnFunction, oListener) Detach event handler
fnFunctionfrom the ‘search’ event of this
- fireSearch(mArguments?) Fire event search to attached listeners.
If a Refresh button is needed:
- getShowRefreshButton() Getter for property
- setShowRefreshButton(bShowRefreshButton) Setter for property
To show the Search button:
- getShowSearchButton() Getter for property
- setShowSearchButton(bShowSearchButton) Setter for property
To ensure the focus is set to input:
- setSelectOnFocus(bSelectOnFocus) Setter for property
- Implement the live search whenever possible.
- Use a manual search only if the amount of data is too large and if your app would otherwise run into performance issues.
- Show an appropriate prompt text:Search if queries are sent to all connected services, or Search In: if the search is limited to a certain source or providing service.
