The community member is asking if it is possible to split or merge multiple indexes, as they have multiple documents they want to query together and in isolation. In the comments, another community member suggests using a query fusion retriever and provides a link to the relevant documentation. However, the original community member has made progress but is now unable to determine the source of the final answer, and they want the query engine to be able to cite the source.
Thanks @Logan M . I've made progress, but now I'm unable to determine my source. Given the final answer I want the query engine to cite it's source. Is it possible?
