The Filter tab provides an easy way of filtering down your search field.
The dropdowns in the Filter tab offer an easy way to filter down your search field using the most important properties available, and at the same time give you an overview of how well-represented the top options are in the current search field via the bar charts.
The following properties are available for filtering in the Filter tab:
- Published Date
- Signal Types
- Tags (Topics)
Note that only the first 5 filters marked bold in the list above are visible by default, while the others can be added.
Filter Bar Charts
Most filters are made up of a dropdown that allows you to select and deselect values for the filter's property (see A below), and a bar chart underneath that allows you to gauge the importance of that particular value (see B below).
- In order to select a single value for the filter, hit the CLEAR ALL option in the filter dropdown (see 1 above) when no search is applied within the dropdown. Then select the option you're interested in. Click outside the dropdown to submit the changes.
- Hovering over a bar chart entry with your mouse will reveal how many documents belong to this value (see 2 above). The same information is also visible in the dropdown.
- You can deselect a value straight from the bar chart, by hovering over an entry and clicking on the "x" that appears (see 3 above).
- Note that only the top 5 options are shown as bars in the bar chart. To see how many more values are part of the current filter, but are not shown, look at the bottom of the widget (see 4 above).
Documents without Values for a Property
It can happen that Signals do not have any value for a property (e.g. if the country of publication is unknown). This category is shown in the dropdown and also in the bar chart if there are enough Signals without a value for that property, or you have filtered by that category. This is displayed as "(No Value)".
In the filter for the published date, you can select either a fixed range of time or a relative range, e.g. the last 2 years.
Saving the search field as a Preset with a relative date range will preserve that information for later. Meaning that if you open the Preset again at a later stage, the time window will have shifted accordingly.
You can add (and also remove) what properties to filter by in the filter customization dialog that opens when clicking on the gear icon at the top-right of the Filter tab (see 1 below).
You can also remove some properties by hitting the "x" that appears when hovering over the properties' bar chart sections.
Interplay with the Power Search
⚠️ Note that you can filter on the same property at the same time using the filter input and the power search. As the different parts of the query each narrow the search field down, only the intersection between the two filters will make it all the way to the view.
Choosing Germany in the Country-dropdown while also having the following power query applied...
country = "US"
... will produce no results, as a Signal can currently only be published in one country and not both in the US and Germany.
Choosing Germany and United States in the Country-dropdown while also having the following power query applied...
country IN ["US", "FR"]
... will produce Signals that have been published in the US as this is the common value.
