Hi, my documents (products) have a price field, and I want to have a "dynamically" calculated range facet for that in the response.
E.g. I want to have this in the response price:[* TO 20] -> 23 price:[20 TO 40] -> 42 price:[40 TO *] -> 33 if prices are between 0 and 60 but price:[* TO 100] -> 23 price:[100 TO 200] -> 42 price:[200 TO *] -> 33 if prices are between 0 and 300 AFAICS I do not have the possibility to specify range queries in my application, as I do not have a clue what's the lowest and highest price in the search result and what are "good" ranges according to the (statistical) distribution of prices in the search result. So if it would be possible to go over each item in the search result I could check the price field and define my ranges for the specific query on solr side and return the price ranges as a facet. Has anybody done s.th. like this before, or is there s.th. that I'm missing and why this approach does not make sense at all? Otherwise, what would be a good starting point to plug in such functionality into solr? Thanx a lot in advance, cheers, Martin
