Re: Hotel Searches
It seems to me like you want to use result grouping by hotel. You'll have to add up the tariffs for each hotel, but that isn't hard.

[...] I think that you might be making this more complex than it needs to be. To start with, have you tested the response time for a search, plus adding the tariffs for the returned results, to see if this meets your needs? It is not feasible to pre-calculate, and cache the results of all possible combinations of 1,2,3,...180 nights from a set of 180 nights. And, that would be just one hotel. What if the user wanted to search for a date range on a chosen set of hotels? I would suggest starting by defining the full extent of what you need, and to decide on acceptable response times which would be driven by business imperatives. You might need to compromise on some things to make this feasible. E.g., if rather than having separate tariffs for each day, you could do with daily, weekly, monthly, etc., rates. Regards, Gora
RE: Hotel Searches
Hi Alex, Thanks for your reply. I saw "prices based on daterange using multipoints ". But this is not my problem. Instead the problem statement for me is pretty simple. Say I have 100 documents each having tariff as field. Doc1 2400.0 Doc2 2500.0 Now a user's search should give me a total tariff. Desired result 4900.0 And this could be any combination for 100 docs it is (100+101)/2. (N*N+1)/2. How can I get these combination of documents already indexed ? Or is there any way to do calculations at runtime? How can I place this constraint that if there is any 1 doc missing in a range don’t give me any result.(if a user asked for hotel tariff from 11th to 13th, and I don’t have tariff for 12th, I shouldn't add 11th and 13th only).

Sorry for that, we just spoiled that thread so posted my question in a fresh thread. Problem is indeed very simple. I have solr documents, which has all the required fields(from db). Say DOC1,DOC2,DOC3.DOCn. Every document has 1 night tariff and I have 180 nights tariff. So a person can search for any combination in these 180 nights. Say a request came to me to give total tariff for 10th to 15th of jan 2013. Now I need to get a sum of tariff field of 6 docs. So how can I keep this data indexed, to avoid search time calculation, and there are other dimensions of this data also beside tariff. Hope this makes sense.
