Abstract
Multi-tenant hosting of inverted indexes for text searches is implemented. Text search requests are routed to different index nodes that cache inverted indexes for different user accounts. Updates to inverted indexes are routed to index nodes that have acquired a lock on an inverted index. The index nodes have access to a common data store that persistently stores the inverted indexes.
