@ -26,7 +26,15 @@ Each filter can define the following values:
* valueName: if the values do not have names (resp. an `<option>` without text content), use this twig template to create a each name. Use `{{ value }}` for the current value.
* query: A twig template which builds a query from the selected value (if the value has not a query defined), e.g. `nwr[amenity={{ value }}]`. If not defined the query will be built from `key` (or the filter ID), `op` and the selected value.
* key: If not overridden by query, use this key for searching. If not defined, use the filter's ID. Can also be an array with a list of keys. You can use wildcards too, e.g. "name:*" to query all localized name tags.
* op: operator to use (if not overridden by query), e.g. '=' (default), '!=', '~', '!~', 'has' (query in semicolon-separated lists like `cuisine=kebap;noodles`).
* op: operator to use (if not overridden by query):
* '=' exact match (default)
* '!=' any value nut this
* '~' regular expression, case sensitive
* '~i' regular expression, case insensitive
* '!~', '!~i' regular expression, negated
* 'has' query in semicolon-separated lists like `cuisine=kebap;noodles`
* 'strsearch' query string parts (e.g. "kai keb" would match "Kaiser Kebap") and query character variants (e.g. "cafe" would match "café").
* show_default: if true, this filter will be shown by default, others need to be added via the select box.
