"if first is selected in the user interface and we have 10 price ranges query would be 120 cluases (12 months * 10 price ranges)"
What would you intend to do with the returned facet-results in this situation? I doubt you want to display 12 categories (1 for each month) ? When a user hasn't selected a date, perhaps it would be more useful to show the cheapest fare regardless of month and facet on that? This would involve introducing 2 new fields: FareDateDontCareStandard, FareDateDontCareFirst Populate these fields on indexing time, by calculating the cheapest fares over all months. This then results in every query having to support at most 20 price ranges (10 for normal and 10 for first class) HTH, Geert-Jan 2010/12/1 lee carroll <lee.a.carr...@googlemail.com> > Hi Erick, > so if i understand you we could do something like: > > if Jan is selected in the user interface and we have 10 price ranges > > query would be 20 cluases in the query (10 * 2 fare clases) > > if first is selected in the user interface and we have 10 price ranges > query would be 120 cluases (12 months * 10 price ranges) > > if first and jan selected with 10 price ranges > query would be 10 cluases > > if we required facets to be returned for all price combinations we'd need > to > supply > 240 cluases > > the user interface would also need to collate the individual fields into > meaningful aggragates for the user (ie numbers by month, numbers by fare > class) > > have I understood or missed the point (i usually have) > > > > > On 1 December 2010 15:00, Erick Erickson <erickerick...@gmail.com> wrote: > > > I'd think that facet.query would work for you, something like: > > &facet=true&facet.query=FareJanStandard:[price1 TO > > price2]&facet.query:fareJanStandard[price2 TO price3] > > You can string as many facet.query clauses as you want, across as many > > fields as you want, they're all > > independent and will get their own sections in the response. > > > > Best > > Erick > > > > On Wed, Dec 1, 2010 at 4:55 AM, lee carroll < > lee.a.carr...@googlemail.com > > >wrote: > > > > > Hi > > > > > > I've built a schema for a proof of concept and it is all working fairly > > > fine, niave maybe but fine. > > > However I think we might run into trouble in the future if we ever use > > > facets. > > > > > > The data models train destination city routes from a origin city: > > > Doc:City > > > Name: cityname [uniq key] > > > CityType: city type values [nine possible values so good for > faceting] > > > ...
