My tomcat access logs have last field as "%D - Time taken to process the request, in millis". I am trying to filter the logs which took more than some number of milliseconds, but it is showing all the logs as a result, I am trying as per lucene "Range Searches" http://lucene.apache.org/core/2_9_4/queryparsersyntax.html
Below filter queries are tried: timetaken: [1000 TO *] timetaken: [1000 TO 5000] timetaken: ['1000' TO *]
