Abstract: In various implementations, a plurality of non-private n-grams that satisfy a privacy criterion may be identified within a search log of private search queries and corresponding post-search activity. A plurality of query patterns may be generated based on the plurality of non-private n-grams. Aggregate search activity statistics associated with each of the plurality of query patterns may be determined from the search log. Aggregate search activity statistics associated with each query pattern may be indicative of search activity associated with a plurality of private search queries in the search log that match the query pattern. In response to a determination that aggregate search activity statistics for a given query pattern satisfy a performance criterion, a methodology for generating data that is presented in response to search queries that match the given query pattern may be altered based on aggregate search activity statistics associated with the given query pattern.
