+
+    You can narrow down search results by excluding one or more subsets. To exclude all results that are matched by a qualifier, prefix the search qualifier with a hyphen (-). However, be careful when searching for command options like '--xxxxxx' because this results in `ERROR_TYPE_QUERY_PARSING_FATAL unable to parse query!`

+    When searching for command-line options:
+    - Search for 'config' instead of '--config'
+    - Search for 'verbose' instead of '--verbose'
