Pharmaceutical companies constantly run clinical tests and need to update and share the results for new medicines. Finding relevant documents containing new medicine development plans, clinical test results, and related activities is always a challenge. It is especially difficult to find specific clinical results on one topic, such as digestive medicines, as several hundred documents can be found in search results from traditional document management systems. The clinical test teams get frustrated and tired of searching endlessly for documents they need. To make matters worse, the number of documents on clinical results from various medicines grows exponentially. As a result, companies have to deal with a lot of redundant documents because people copy every version to repositories, which means IT has to periodically manage and remove related documents to overcome overwhelming indexing issues.
