This paper presents the use of folksonomy concepts in a software component search engine as an alternative to improve the search result quality, covering from specification to implementation. A case study was performed in order to evaluate its performance and viability. Additionally, a set of requirements to perform component search and retrieval with folksonomy are presented, beyond the architectural and implementation aspects that accomplishes the tool. The case study indicates the suit of different search techniques is better than using separately. The engine's current version combines keyword, facet-based and folksonomy search techniques.
