Allow users to visually narrow results between two number ranges.
|Other data source||Use this setting if you want to use a separate value for the upper limit|
|Compare type||Basic: selected values must be entirely in range
Intersect: selected values must be at least partially in range
|Prefix||The text that appears before each slider value|
|Suffix||The text that appears after each slider value|
|Format||The number format|
|Step||The amount of increase between intervals (default = 1)|
If a slider facet uses both data sources, the lower value is stored as
facet_value, and the upper value is stored as
facet_display_value in the index table.
