Filtering
Filters narrow a list view down to a subset that matches one or more criteria. They live on the left side of any list page and apply on top of any active search term.

Where filters live
Every entity type has its own list view (open one from the left sidebar). The filter panel appears on the left of that list. Available filters are different per entity type — Media has many (keyword, marine region, partner, date, …) while a vocabulary list like Languages has only a handful.
Anatomy of the filter panel
Filters fall into three families:
| Filter type | Examples | UI control |
|---|---|---|
| Selectable list | Context, Keyword, Marine region, Asset category, Partner | A search-as-you-type dropdown |
| Date / range | Creation date, Embargo date | A date-picker with from/to |
| Yes/no / enum | Public / Private, has-mediafile | A toggle or radio set |
Tip: most list filters support multi-select. Selecting two keywords means either keyword will match, not both.
Applying a filter
- Open the list of the entity type you want to filter (e.g. Sidebar → Media).
- In the filter panel, find the field you want to filter on.
- For a list filter: start typing in the dropdown and pick one or more values.
- The results update automatically as you select.
- Active filters appear as chips above the result list — you can remove a single one by clicking the
×on the chip, or Clear all to reset.

Combining filters
Filters combine with AND between fields and OR within a field:
- Keyword:
Coastal management+Beach profiles→ media tagged with either keyword. - Keyword:
Coastal management+ Marine region:North Sea→ media tagged withCoastal managementAND belonging toNorth Sea.
Add a free-text search on top of that and you get search ∩ filter — useful when there are many similar entities.
Frequently useful filter combinations
| Goal | How to filter |
|---|---|
| Recently uploaded media that still need review | Filter Media by Public/Private = Private + sort by Last modified descending |
| Everything from a partner organisation | Filter Media by Partner = chosen partner |
| Items in a specific archival collection | Filter Media by Archival collection |
| Photos taken at a particular site | Filter Media by Marine region + free-text search on locality |
| Files with embargo expiring soon | Filter Mediafiles by Embargo date range |
Date filters
Date filters expect a from–to range. Leave one side empty to get an open-ended range:
- From
01/01/2024, to empty → everything from January 2024 onwards. - From empty, to
31/12/2023→ everything up to end of 2023.
Format on screen is dd/mm/yyyy regardless of locale.
Saving a filter set
Same flow as in Searching → Saved searches: apply your filters, click Save search in the toolbar, name it. The saved entry remembers both the filter set and any active search term.
Things to watch out for
- Context filter. Most environments default to a single context (e.g. general vliz); if a colleague's entity isn't visible it may be in another context.
- Indirect filters. Some filter fields query through a relation. Filtering Media by Album title uses the album's title, not the media's. The filter dropdown shows the same labels you'd see on the album list.
- Resetting. Clear all removes filter selections but keeps your sort order. Reload the page if you also want default sorting back.
- Permissions. If you don't have access to certain entities, they won't appear in the dropdowns — even if they technically exist.
