Re: Field type change / copy field

[Jan Høydahl <ja...@cominvent.com>]

Hi,

Is this simply for returning a date string, or do you really need a full-blown Date object for your years?
I'd probably go with a "tint" field for the faceting on year, if year is the lowest date resolution you need.
If you need to convert 2008 to 2008-01-01T00:00:00Z to put into a real "date" field, then send it in from your client twice or write a UpdateProcessor to construct the date field based on the year field.

Its field type is of the class 'solr.TrieDateField' that requires canonical date representation. Is there a way in solr to extend the simple year to <facet_year>2008-01-01T00:00:00Z</facet_year>. Or, do i have to solve the problem in preprocessing, before posting?
