11. A system comprising: one or more processors; and a data store coupled to the one or more processors having instructions stored thereon which, when executed by the one or more processors, causes the one or more processors to perform operations comprising: receiving, by the one or more processors, trigger query data, the trigger query data identifying one or more trigger queries and one or more sets of authoritative users, each set of authoritative users being associated with a respective trigger query; generating, by the one or more processors, a first trigger query and authoritative user pair, the first trigger query and authoritative user pair identifying a first trigger query and an authoritative user from a set of authoritative users associated with the trigger query; generating, by the one or more processors, a second trigger query and authoritative user pair, the second trigger query and authoritative user pair identifying a second trigger query and the authoritative user; generating, by the one or more processors, a first snippet based on user data, the user data being associated with the authoritative user in one or more computer-implemented services, the first snippet being specific to the first trigger query and specific to the authoritative user, generating, by the one or more processors, a second snippet based the user data, the second snippet being different from the first snipped, and being specific to the second trigger query and specific to the authoritative user; and storing, by the one or more processors, the first and second snippets in computer-readable memory.
