Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage medium, for facilitating auto-completion of search queries in a group based document sharing environment. In one aspect, a method includes actions of maintaining a prefix index that includes prefix index entries. Each prefix index entry may include a prefix, a group identifier, and a portion of a document. Additional actions may include receiving input from a user that is associated with a search field, determining a user identifier associated with the user that submitted the received input, mapping the user identifier to a particular group identifier, obtaining one or multiple candidate query suggestions based on the received input and the prefix index, and selecting a subset of the candidate query suggestions based on the particular group identifier. Other actions may include providing the subset of candidate query suggestions to the user.
