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

1. Open the list of the entity type you want to filter (e.g. Sidebar → Media).
2. In the filter panel, find the field you want to filter on.
3. For a list filter: start typing in the dropdown and pick one or more values.
4. The results update automatically as you select.
5. 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 with Coastal management AND belonging to North 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.
