Abstract
A data storage and retrieval system with parameterized category definitions and dynamically generated search indices. A parameterized category definition for a family of categories is obtained consisting of a parameterized predicate, such that parameter values can be provided with a search query to identify information items that match a category within the family of categories. The parameterized category definition is divided into a parameterized part and a static part. The static part is used to create associations between information items and the family of categories. The disclosed system processes the parameterized part of the category family definition to dynamically generate one or more search indices. The disclosed system determines whether any existing indices match the parameters of the parameterized part, and can accordingly be re-used. In the case where one or more indices are missing that are needed to support the parameterized part of the category family definition, the disclosed system operates to create them based on information items associated with the family of categories based on the static part of the parameterized category definition. Queries supplying values for the parameters of the parameterized category definition for the family of categories are subsequently processed to identify information items belonging to specific, dynamically defined categories within the family of categories.
