The CodeKoan Search Engine

A Source Code Pattern Search Engine

Codekoan is a special search engine, which lets users submit large source code documents as queries. In these source code documents Codekoan recognizes approximate reuses of short code fragments from a large index. Codekoan's algorithm is mostly programming language independent but it has some small programming language specific parts.

Smart Source Code Search

A lot of publicly available code search tools use some form of string based search. CodeKoan uses a more complex token based algorithm that searches for source code based on the "micro-structure" of source code. The advantage of the algorithm is, that it is capable of recognizing short code patterns over a variety of different application domains.
