Abstract: Multiple search indexes can be served from a common set of resources. Instead of requiring a processor to be dedicated to serving a single search index, a processor can provide responsive documents for search queries that are based on different ranking algorithms and/or different sets of documents.

Abstract: A provisioning system is described for dynamically and automatically allocating index server resources to different respective uses. For example, the provisioning system can allocate index server resources among different search-related production uses, different analysis-related uses, different testing-related uses, and so on. In one case, the provisioning system includes an allocation manager module that receives information that has a bearing on the allocation of index server resources. Based on this information, the allocation manager module determines an allocation of index server resources and sends instructions to an indexing system to carry out the allocation. In one case, the indexing system respond to the instructions by allocating rows of index server resources to different partner entities which have requested index server resources. Each row can also implement custom index information and/or custom processing functionality for use by particular partner entities.
