Cocoon, Lucene and Date Ranges

[Sal Mangano <sa...@into-technology.com>]

I am using cocoon and lucene with great success on a current project. I am
using Cocoon's search generator (<map:generate type="search"/>). The one
part I have not figured out is how to implement date range filtering in my
search. I need to limit searches via a start date, end date or both. I think
I have a general idea of how to get the date info into the Lucene index but
don't know what needs to be done next. I have the feeling that I may need
implement my own generator or extend the existing one but before I go down
that path I'd like to know if there is a solution within the context of
available components. 

Thanks.

I am going to answer my own question in case anyone else can benefit. It
turns out the answer is simple! Everything comes for free (I was just being
dense). If the lucene index was greated with date fields of the form
YYYYMMDD then you simply have to use a query string of the form
"date:[YYYYMMDD TO YYYYMMDD]" (eg. date:[20000101 TO 20040607]). Piece of
cake. In my case the date format was ISO (YYYY-MM-DD) but this works just as
well by sticking the dashes in the dates in the range.
