Abstract: The processing of search queries for a customer using a set of resource can balance performance with cost, in order to ensure that the processing satisfies customer performance requirements while attempting to minimize the cost to the customer for obtaining that performance. In addition to dynamically updating the allocation of resources used to process the requests, such as to change the number or sizes of allocated resources, the number of indexes to be searched can be updated as well. For example, a search index can be divided into two sub-indexes against which queries can be executed concurrently in order to reduce the latency by about a half. Adjustments to the indexes and resources can be balanced to minimize cost while retaining performance, which can include rejoining sub-indexes or reducing the number of resource as appropriate.
