The current search interface does not yet support the explicit search for specific workflows. In order to add these, the following should be done: - [x] Add a new filter menu "Properties/Workflow" - [x] Add filtering and statistics for the following workflows: - Geometry optimization - Molecular dynamics - Phonons - Elastic constants - Single point - [x] Create more detailed subsection for geometry optimization containing sliders for `final_energy_maximum`, `final_force_maximum`, `final_displacement_maximum`. Ensure that these are created and indexed. - [x] Optimize terms aggregations by utilizing the [ES include-option](https://www.elastic.co/guide/en/elasticsearch//reference/master/search-aggregations-bucket-terms-aggregation.html#_filtering_values_4). With this option, all aggregations that target a subset of a specific metainfo (e.g. the new workflow filter that tries to find relevant definitions within `metadata.quantitites`) will be much more optimized as they don't have to gather aggregations for all terms. - [x] Add the searchable geometry optimization filters (`final_energy_difference` etc.) to be shown in the overview page.
