Example Queries​

object_type == "ODF"
  && @match_object_meta($properties.generator regex("MicrosoftWord"))
  && @has_child(object_type == "Text"
       && @match_object_meta($natural_language_sentiment.compound < 0)
     )
  • This query matches an ODF text document with generator metadata entry containing MicrosoftWord substring (case sensitive), and from which a Text object with negative sentiment is extracted.
