Facets

Most faceting will work as described in the Haystack documentation with the exception of date_facet.

xapian-haystack employs a custom format for the gap parameter where gap is a string with a unit of time and optional value seperated by an ‘=’ operator.

For example:

# Facet every seven days
SearchQuerySet().filter(content='foo').date_facet('pub_date', start_date=datetime.date(2009, 6, 7), end_date=datetime.date(2009, 7, 7), gap='days=7')

or

# Facet every month
SearchQuerySet().filter(content='foo').date_facet('pub_date', start_date=datetime.date(2009, 6, 7), end_date=datetime.date(2009, 7, 7), gap='month')

The gap can be any one of the following:

• year
• years
• month
• months
• day
• days
• hour
• hours
• minute
• minutes
• second
• seconds
