US Patent 8667456 Cloud-based indexing for integrated development environments

Disclosed are systems, methods, and devices for providing cloud-based indexing services to cloud-based and client-based software development environments. For example, integrated development environment (IDE) services may be provided at a client device via a cloud-based indexing service, and an indexing request related to source code at least partially loaded at the client device transmitted to the cloud-based indexing service with respect to a type of indexing request selected from a code completion request, a usages request, an annotations listing request, and a refactoring request. The cloud-based indexing service may then access one or more indexes maintained at the cloud-based indexing service, and provide responsive index information to the client device, the index information included in the responsive index information being less than all index information from the one or more indexes corresponding to the source code at least partially loaded at the client device. The responsive index information can then be displayed at the client device.
