Abstract:
1. A query processing method, performed by a search engine server system, comprising: receiving, from a client system distinct from the search engine server system, a search query having one or more query terms; in response to receiving the search query: wherein generating the content snippet comprises: receiving a set of first token identifiers, comprising compressed content of the respective search result document, from a compressed document repository; performing a first decompression operation by applying one or more first mappings to the set of first token identifiers to provide a set of second token identifiers; and performing a second decompression operation by applying a second mapping to the set of second token identifiers to recover uncompressed content comprising a portion of the respective document; wherein the first decompression operation produces a respective second token identifier for each first token identifier, the set of second token identifiers has a same number of distinct token identifiers as the first set of token identifiers, and the second decompression operation produces a respective uncompressed content item for each second token identifier; and wherein each first token identifier comprises an M bit integer value, and each second token identifier comprises an N bit integer value, N and M are positive integers and N is greater than M.
