Query formation and modification techniques are described. In one or more embodiments, a query is received that is formed in a text field as a phrase in a human-readable language that includes a visual indicator that represents a missing term that is a subject of the query. Based on the query, a defined database is searched, and one or more modified versions of the phrase are presented that replace the visual indicator with a respective result of the searching. In addition, one or more options are presented that are selectable to automatically complete the phrase as a sentence in the human-readable language.
