Truncated autosuggest on a touchscreen computing device

A computer device may reduce user error when constructing a search query. The computing device may display one or more search terms within a search box based on user input. The computing device may display initial autosuggest candidates and detect a user-selected initial autosuggest candidate. The computing device may display the user-selected initial autosuggest candidate within the search box as a preliminary search query, without automatically initiating a web search for the preliminary search query. The computing device may receive new autosuggest candidates having the preliminary search query as a common prefix, generate truncated autosuggest candidates by removing the common prefix from each new autosuggest candidate, and display the truncated autosuggest candidates.
