Definition
The can_filter parameter lets you prohibit a dimension or measure from being used as a filter. For example:
dimension: description {
  can_filter: no
}
The default value of can_filter is true, meaning that dimensions and measures can be used as filters as you would expect. However, there may be some cases when a field may be too demanding to search (like a large text description), and in these situations you can prevent that field from being used as a filter. Users won't see a FILTER option when they hover over the field.
Note that can_filter cannot be used with:
- Measures of 
type: list, because they cannot be filtered on anyway filterfields, which only exist for the purpose of filtering- The 
filtersparameter that is used with measures 
Additionally, drilling into a field won't be permitted if the drill requires a filterable dimension and the can_filter parameter is set to no. This occurs when you:
- Attempt to drill on a dimension that uses 
can_filter: no - Attempt to drill on a measure if a 
can_filter: nodimension is used in the same query as that measure 
See the documentation pages for drill_fields (for fields) and drill_fields (for views).
