I'll add/start with my proposal ;) Document-meta fields: + visiblefrom [long] + visibleto [long]
Query or query filter: (*:* -visiblefrom:[* TO *] AND -visibleto:[* TO *]) OR (*:* -visiblefrom:[* TO *] AND visibleto:[ <now in ms> TO *]) OR (*:* -visibleto:[ * TO *] AND visiblefrom:[* TO <now in ms>]) OR ( visiblefrom:[* TO <now in ms>] AND visibleto:[ <now in ms> TO *]) -----Ursprüngliche Nachricht----- Von: Clemens Wyss DEV [mailto:clemens...@mysign.ch] Gesendet: Montag, 12. Januar 2015 09:40 An: java-user@lucene.apache.org Betreff: howto: handle temporal visibility of a document? We have documents that are not always visible (visiblefrom-visibleto). In order to not have to query the originating object of the document whether it is currently visible (after the query), we'd like to put metadata into the documents, so that the visibility can be determined at query-time (by the query itself or a query filter). Any suggestions on how to index and query this metadata?
