Subject Price Range Faceting Based on Date Constraints
Date Thu, 21 May 2015 12:58:52 GMT
Hi,

I have an unique requirement to facet on product prices based on date
constraints, for which I have been thinking for a solution for a couple of
days now, but to no avail. The details are as follows:

1. Each product can have multiple prices, each price has a start-date and an
end-date.
2. At search time, we need to facet on price ranges ($0 - $5, $5-$20,
$20-$50...)
3. When faceting, a date is first determined. It can be either the current
system date or a future date (call it date X)
4. For each product, the price to be used for faceting has to meet the
following condition: start-date < date X, and date X < end-date, in other
words, date X has to fall within start-date and end-date.
5. My Solr version: 3.5

Hopefully I explained the requirement clearly. I have tried single price
field with multivalue and each price value has startdate and enddate
appended. I also tried one field per price with the field name containing
both startdate and enddate. Neither approach seems to work. Can someone
please shed some light as to how the index should be designed and what the
facet query should look like?

Thanks in advance for your help!
