So that page referenced describes local-params, and describes the special "v" local-param. But first, see a list of all query parsers (which lists "field"): https://cwiki.apache.org/confluence/display/solr/Other+Parsers and https://cwiki.apache.org/confluence/display/solr/The+Standard+Query+Parser for the "lucene" one.
The "op" param is rather unique... it's not defined by any query parser. A trick is done in which a custom field type (DateRangeField in this case) is able to inspect the local-params, and thus define and use params it needs. https://cwiki.apache.org/confluence/display/solr/Working+with+Dates "More DateRangeField Details" mentions "op". {!lucene df=dateRange op=Contains}... would also work. I don't know of any other local-param used in this way.
