Abstract: In one embodiment, a method includes receiving a text query inputted by a first user of an online social network, the text query including one or more n-grams. The method also includes identifying a first set of candidate keywords from multiple keywords stored on a local cache of a client system, each keyword being extracted from a source of multiple sources associated with the online social network, where each candidate keyword in the first set matches one or more n-grams of the text query and calculating a rank for each of the identified candidate keywords based at least in part on the source associated with the candidate keyword. The method also includes displaying, in response to the first user inputting the one or more n-grams of the text query, one or more suggested queries, each suggested query including an identified candidate keyword having a rank higher than a threshold rank.
