Filtering / sorting results based on results from different core

["Manepalli, Kalyan" <KA...@orbitz.com>]

Hello,
            In our current setup we have 2 cores. First core contains hotel content information and second core contains pricing information.
I was looking for a way to combine this information at query time so that I can filter / sort results by price.
Is there any way to do this. An example of query would be;
Select all hotels in Chicago sort by price.
I cannot combine both the cores since the frequency of indexing differs. We index prices more often that hotel content.

Any suggestions in this regard will be very helpful

Thanks,
