Site Search UX: Suggestions, Results, and No-Match Recovery
Search is a conversation between a person's words and the content a product can find. A useful search interface supports that conversation before, during, and after submission: it helps people express a query, shows what matched, and offers a way forward when nothing did.
Faceted Filtering UX: Help Users Narrow Results With Confidence
Adding autocomplete is not enough. Suggestions that are irrelevant, difficult to navigate, or misleading can make search less trustworthy.
Make the search field easy to recognize and use
Place the search control where people expect to find it and label it clearly. Keep the submitted query visible on the results page so people can refine it without starting over. For large content collections, show the result count and explain any active filters or scope.
If search only covers a particular area—such as help articles, products, or one project—make that scope visible. Users should not have to guess whether a missing result is absent from the whole service or simply outside the current search.
Design useful suggestions, not decoration
Suggestions can help people avoid typos, find the terminology used by the site, and reach a relevant result with less typing. Nielsen Norman Group recommends ensuring that suggested queries lead to good results and differentiating the suggestion text from the characters already entered.
Keep the list focused. A long menu of weak suggestions adds noise and makes it harder to scan. If suggestions include categories or scope, make those distinctions understandable rather than relying on small icons alone.
Suggestions are optional assistance, not a replacement for the query. People must be able to finish typing and submit their own terms even when the dropdown is open.
Make autocomplete work beyond a pointer
Autocomplete needs an intentional keyboard and assistive-technology interaction model. Users should be able to move between the input and options, understand which option is active, choose or dismiss a suggestion, and continue typing without losing the query.
Keep focus behavior predictable and ensure the menu does not cover the field or important content at narrow widths. Test the control with keyboard-only navigation and screen readers; a visually highlighted option is not automatically exposed as the active suggestion.
Help users recover from no matches
When nothing matches, preserve the search text and say plainly that no results were found. Offer a relevant next step:
- Check for a likely spelling correction without silently replacing the query.
- Remove a filter or expand the search scope.
- Suggest a broader term or a related category.
- Provide a route to browse the content instead.
Do not show unrelated results simply to avoid an empty state. A confident but irrelevant result is worse than a clear explanation that invites the user to refine the search.
Use search evidence to improve content and retrieval
Review common queries, abandoned searches, and repeated refinements to understand where terminology, information architecture, or retrieval may be failing. Treat query logs with appropriate privacy controls and avoid assuming that every popular query represents a successful task.
Test real tasks with people who know the product and people who do not. Observe whether they can find an item, determine why a result matched, and recover when their first wording does not work.
