Hi,
I saw this post :
http://lucene.472066.n3.nabble.com/Multiple-Facet-Dates-td495480.html
I didn't see work in progress or plans about this feature on the list
and bugtracker.
Does someone already created a patch, pof, ... I wouldn't have been
able to find ?
From my naïve point of view the ratio "usefulness" / "added code
complexity" appears as high.
My use-case is to provide, in one request :
- the results count for each one of several years (tag-based exclusion)
- the results count for each month of a given year
- the results count for each day of a given month and year)
I pretty sure someone here already encountered the above, isn't ?
After having understood :
"This parameter can be specified on a per field basis."
I created 3 more copy-fields, it's then obvious :
// the real constraint requested
fq={!tag=datefq}date
f.date.facet.date.start=2008-12-08T06:00:00Z
f.date.facet.date.end=2008-12-09T06:00:00Z
f.date.facet.date.gap=+1DAY
// three more field for the total
facet.date={!ex%3Ddatefq}date_for_year
facet.date={!ex%3Ddatefq}date_for_year_month
facet.date={!ex%3Ddatefq}date_for_year_month_day
// the count for all year without the constraint
f.date_for_year.facet.date.start=1970-01-01T06:00:00Z
f.date_for_year.facet.date.end=2011-01-01T06:00:00Z
f.date_for_year.facet.date.gap=+1YEAR
// the count for all month of the year requested (2008) without the
constraint
f.date_for_year_month.facet.date.start=2008-01-01T06:00:00Z
f.date_for_year_month.facet.date.end=2008-12-31T06:00:00Z
f.date_for_year_month.facet.date.gap=+1MONTH
// idem for the days...
Thanks for your work !
