ABSTRACT
‘Query’ may be defined as retrieval of meaningful information. In search, true success comes from understanding what the user is asking from their query. Mistakes most commonly made – is the failure to understand the query processing stage and the attempt to perform too many calculations across a large result set during result processing, loading the system beyond its query rate capacity, generating a backlog of queries, which creates higher query latencies and possibly disruption of services.
Keywords: Query Processing, Query optimization, Contextual queries.
