Change request repositories are fundamental for software maintenance. However, their benefits do not come without issues. We analyzed 142 studies to characterize the research on these issues and provide directions for future investigation. The studies were classified into topics and grouped into two dimensions: challenges and opportunities. Then, the challenges were classified in accordance with an existing taxonomy for information retrieval models. Additionally, we investigated different change request repositories to understand whether and how they addressed the topics identified.
