I'm in a process on learning if Orchard is best suited for what a customer has asked us to implement.
We need a way to combine the search module wich orchard provides, wich indexes contents of the site, with a second search engine wich querys a internal system.
So, when the user press the search button on any page, the query is sent to the orchard's search module and to the internal search module at the same time, and the results then are presented to the user combined (maybe on two different columns).
What would it take to develop such a feature for us? Would we have to modify the search module in orchard or this module has known extensibility points to do something like this? Is this a easy thing to do or a complex/tricky/hacky thing?
I'm not asking for a full implementation or detailed steps, just an opinion from colleages who are much more experienced than I on this software
