In a knowledge management project I need to use a wiki engine ( I'm thinking about DokuWiki ) and a Question and Answer system ( I'm thinking about Question2Answer), and I need to create a Search Funcionality that search in both systems (Wiki and QA) and return what has been found. ( Like a Google of the two systems in same time)
Anyone knows a direction to help me how to do it properly?
I don't know about the wiki side, but you can write your own search plugin for Question2Answer that let you integrate your own search results into those of Q2A. See the docs for more info.
If your wiki software has an API or functions you can call to find search results, then in Q2A you can use the process_search method in your plugin, call your wiki search function and add the results to the Q2A results.
Having said all that, you might find it easier to integrate Google Custom Search Engine into your site!
