  Maybe we should rework this and add a citation variable somewhere?

Looking at the code, there are numerous workarounds to combine the pipeline and search to one variable, when the more natural solution is to have a system to use both simulaneously without modifying the pipeline or search values. This should be easier to maintain into the future and avoid bugs such as in #124 (closed).
