According to Jakob Nielsen search is such a prominent part of the web experience that users have developed a precise idea of how it's supposed to work. Deviating from users' expectations almost always causes usability problems.
Users expect search to have three components:
- A box where they can type words
- A button labeled "search" that they click to run the search
- A list of top results that's linear, prioritized, and appears on a new page
Given how ingrained it is, it's crucial to avoid invoking user's expectations for other interactions. Users' expectations are so strong that the label "Search" equals keyword searching, not other types of search.
