87 +==== Select an experimental approach ====
88 +
89 +Similar to the facetted filters in the Knowledge Graph Search UI, we can refine our query by defining the experimental approach of our interest, for example electrophysiology.

91 +To ensure that all dataset versions with electrophysiology are queried, and none of the dataset versions without electrophysiology, we make this property required and we apply a filter to the label we are searching for (i.e. electrophysiology).
