I’d make this fields as: Date, Keyword (for aggregations), Keyword (for aggregations), Text(allow word cloud)
The word cloud for the Body might be nice, but more importantly I can search for e.g. “bomb” in there - would that work? There might be some aggergations done on Category e.g. to count how many percent of the documents are of what category, but should Ref_Nr be keywords? Or Integer?
Assuming you already mapped as date in any ES compatible format, in the entity table settings/field tab, unlock the changes and click on the format link (default in the screenshot):
Finally, when I ingested I used the Siren NLP plugin and I see it works e.g. it creates columns siren.nlp.ids.entity/person with correctly identified persons. I wanted to put in the dashboard the body along with these identified words e.g. siren.nlp.taxonomy_annotated.body and as one of the columns, but these do not show - how to show those words highlighted?
@Davide_Paoletti wondering if the record table / NLP annotation is available for the community edition?
