Order by an expression in Solr

由 自古美人都是妖i 提交于 2019-12-19 07:28:07
问题 In SQL you can order by an expression like: SELECT * FROM a ORDER BY CASE WHEN a.Category = 20 THEN 1 ELSE 0 DESC so records who have Category = 20 are on top. Is this possible in Solr? 回答1: Solr doesn't have an if/then (at least not until 4.0), but it does have a map function and the ability to use function queries in your sort. You can probably use something like this in your sort to achieve what you're after: ?q=*&sort=map(category,20,20,case,0),score desc (untested) Here is a thread that

SOLR travel site: on date queries

由 好久不见. 提交于 2019-12-19 04:44:06
问题 I was looking to implement SOLR for a Hotel bookings site. Search based on location, hotel names, facilities works very well and so does the faceting. What I have not been able to figure out is how to search for a hotel given Checkin and Checkout dates. Eg: User will search for search query - "Hotels in Newyork" and select CheckIn Date: 10th Feb 2012 and CheckOut Date: 12 Feb 2012 from the date selection box. This is how I have the data - Hotel_Name 10thFeb2012 11thFEB2012 ........ 31DEC2012
