Pre-computed impression lists
First Claim
1. A computer-implemented method of identifying web page impressions that satisfy a query comprising:
- receiving, from a client device, a query having a number of criteria greater than a predetermined number, wherein the number of criteria and the predetermined number are both greater than zero and less than infinity, and the query specifies one or more attributes of web page impressions;
generating a plurality of sub-queries from the query, including generating a first sub-query associated with first criteria and generating a second sub-query associated with second criteria, wherein each criterion of the query is represented in at least one of the plurality of sub-queries, and the first criteria and the second criteria are mutually exclusive;
obtaining a response for each of the sub-queries, from a database of web page impressions, wherein each response comprises identifiers of web page impressions satisfying criteria of the associated sub-query;
generating a response to the query by comparing the responses to the sub-queries; and
providing an answer to the client device based at least in part on said generating a response to the query by comparing the responses to the sub-queries.

Abstract
Systems, methods, and computer program products identify one or more web page impressions satisfying one or more simply queries, each of the one or more web page impressions associated with a respective impression ID. Respective impression IDs of the one or more web pages satisfying the one or more simple queries are stored in an impression log. Subsequent to storing the respective impression IDs, a query is received from a client device, and a number of impression IDs for the one or more web pages satisfying the query are identified based on the identified one or more web page impressions satisfying the one or more simple queries.

8. A data processing apparatus coupled to a database of web page impressions, wherein said data processing apparatus includes a processor configured to:
-
receive, from a client device, a query having a number of criteria greater than a predetermined number, wherein the number of criteria and the predetermined number are both greater than zero and less than infinity, and the query specifies one or more attributes of web page impressions; generate a plurality of sub-queries from the query, wherein each criterion of the query is represented in at least one of the plurality of sub-queries; obtain a response for each of the sub-queries, from the database of web page impressions, wherein each response comprises identifiers of web page impressions satisfying criteria of the associated sub-query; generate a response to the query by comparing the responses to the sub-queries; and provide an answer to the client device based at least in part on the generated response, by at least providing a number of web page impressions that have attributes that meet the criteria of the query. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer-readable storage device having computer-executable instructions embodied thereon, wherein when executed by a data processing apparatus coupled to a database of web page impressions, the computer-executable instructions cause the data processing apparatus to perform the steps of:
-
computing a response to an initial query; storing a result of the initial query in an impression log; receiving, from a client device, a subsequent query having a number of criteria greater than a predetermined number, wherein the number of criteria and the predetermined number are both greater than zero and less than infinity, and the subsequent query specifies one or more attributes of web page impressions; generating a plurality of sub-queries from the subsequent query, wherein each criterion of the subsequent query is represented in at least one of the plurality of sub-queries; obtaining a response for each of the sub-queries, from the database of web page impressions, wherein each response comprises identifiers of web page impressions satisfying criteria of the associated sub-query; generating a response to the subsequent query by comparing the responses to the sub-queries; and providing an answer to the client device based at least in part on said generating a response to the subsequent query by comparing the responses to the sub-queries. - View Dependent Claims (16, 17)
