   Domains can also be expanded by using the `excludeTags` keyword to discard or ignore particular tagged query filters.
   
  -This is used in the example below to show the top two manufacturers matching a search.  The search results match the filter `manu_id_s:apple`, but the computed facet discards this filter and operates a domain widened by discarding the `manu_id_s`  filter.

positive.code: 
  The value of `filter` can be a single query to treat as a filter, or a JSON list of filter queries.  Each query can be:
  
  * a string containing a query in Solr query syntax
  * a reference to a request parameter containing Solr query syntax, of the form: `{param : <request_param_name>}`.
  The referred parameter might have 0 (absent) or many values.
  ** When no values specified, no filter is applied and no error is thrown
  ** When many values are specified, each value is parsed and used as filters
  
  When a `filter` option is combined with other `domain` changing options, the filtering is applied _after_ the other domain changes take place.

  The value of `excludeTags` can be a single string tag, an array of string tags, or comma-separated tags in the single string.
  
  When an `excludeTags` option is combined with other `domain` changing options, it expands the domain _before_ any other domain changes take place.
