A facility for populating a segment from a population of individuals is described. The facility accesses two or more fact tables, each containing data about attributes of a number of users who are members of a number of arbitrary user groups. The facility generates a number of column chunks from each fact table. Each column chunk contains data about a single attribute of users that are members of a single arbitrary user group. The facility applies a segment membership test that tests particular user attributes to each arbitrary user groups in turn. In doing so, the facility collects the generated column chunks that contain data about attributes of users that are members of the current arbitrary user group tested by the segment membership test. The facility applies the segment membership test to the collected column chunks to identify individuals within the arbitrary user group that satisfy the segment membership test.

User segment population techniques

A information retrieval system wherein design and content are separated. Within a section of a title, a designer can layout pages with controls that define areas for content to be inserted into the pages. Two commonly used controls in the system are a static story control, wherein a preselected story is statically placed on a page in the area defined by the control, and a dynamic story control, wherein the designer defines search objects to retrieve stories. An information retrieval (IR) server indexes and searches stories in titles. Indexing takes place when a title is released to the network by a publisher workstation. The IR server interrelates title, section and story objects by their globally unique identifiers and creates a routing table which is used to locate objects across multiple database partitions. The IR search service is requested in two different ways at customer runtime. The first way is the resolution of the search objects to retrieve matching stories. The retrieved stories are concatenated and poured into the area defined by the dynamic control when the title is viewed. In the second way, the IR search service is requested when a search is initiated by a customer using a 'find' dialog to search across all stories in one or more titles, both dynamic and static.
