It is possible that the criteria you have used are too specific so that no individuals meet all the requested characteristics. In that case, we recommend restarting your search with fewer criteria.

Using the "OPTIONAL clause" in SPARQL queries is a potential solution to make certain criteria optional, thereby giving you more results. This allows additional information to be included if available, without excluding the results that do not meet the criteria. We understand that this feature may seem complex. We are currently working on a detailed tutorial that will explain how to use the best techniques to optimise your searches. This guide will soon be available to guide you step by step.
