Abstract
A method and system for optimizing resource usage in an information retrieval system. Meta information in query results describes data items identified by identifiers. A chunk of the identifiers and a set of meta information are loaded into a first cache and a second cache, respectively. A portion of the set of meta information is being viewed by a user. The portion describes a data item identified by an identifier included in the chunk and in a sub-chunk of identifiers that identifies data items described by the set of meta information. If a position of the identifier in the sub-chunk satisfies a first criterion, then a second set of meta information is preloaded into the second cache. If a position of the identifier in the chunk satisfies a second criterion, then a second chunk of the identifiers is preloaded into the first cache.
