Abstract

Techniques are provided for a metasearch infrastructure. The metasearch infrastructure supports one or more of the following: hotel matching, backend support of user queries, frontend support for user queries, a cache layer that groups or organizes cached data in storage based on hotel location, scoring and ranking on the client side, experiments and rankers, duplicate booking prevention, blacklisting hotels, and indexing that utilizes a document-independent data structure to store index values.
