Golem Full-text Search Engine

Golem Network is a cloud computing power service where everyone can develop, manage and execute workloads in an unstoppable, inexpensive and censorship-free environment.

Since Beta.2 Golem supports a new model of computation – services. In contrast with batch tasks, services are expected to be long-running processes that don't have any natural completion point but rather are started and stopped on explicit command. The goal of this project is to build a full-text search service on Golem. The service allows its users to perform search queries over a corpus of documents submitted by the requestor during deployment.
