Rafał Kuć commented on SOLR-1023: --------------------------------- I should be able to supply a patch adding date support for StatsCommponent and for string fields too. What I think is what other statistics appart from minimum and maximum would be usefull ? I`m thinking about count and missing. Any other ideas ? > StatsComponent should support dates (and other non-numeric fields) > ------------------------------------------------------------------ > > Key: SOLR-1023 > URL: https://issues.apache.org/jira/browse/SOLR-1023 > Project: Solr > Issue Type: New Feature > Affects Versions: 1.4 > Environment: Mac OS 10.5, java version "1.5.0_16" > Reporter: Peter Wolanin > Fix For: 1.5 > > > Currently, the StatsComponent only supports single-value numeric fields: > http://wiki.apache.org/solr/StatsComponent > trying to use it with a date field I get an exception like: > java.lang.NumberFormatException: For input string: "2009-01-27T20:04:04Z" > trying to use it with a string I get an error 400 "Stats are valid for > single valued numeric values." > For constructing date facets it would be very useful to be able to get the > minimum and maximum date from a DateField within a set of documents. In > general, it could be useful to get the minimum and maximum from any field > type that can be compared, though that's of less importance. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
