Finding code clones in the open source systems is one of important and demanding features for efficient and safe reuse of existing open source software. In this paper, we propose a novel search model, open code clone search, to explore code clones in open source repositories on the Internet. Based on this search model, we have designed and implemented a prototype system named Open CCFinder. This system takes a query code fragment as its input, and returns the code fragments containing the code clones with the query. It utilizes publicly available code search engines as external resources. Using Open CCFinder, We have conducted various case studies for Java code. These experiments show the applicability of our system.
