Is it possible to create a scripted field which reads a value from indexA, performs a search in indexB, then takes that value and stores it back in indexA?
For example, I have an index filled with IP addresses and the companies who own them. In a separate index, I have an IP address and I need to know the company where this traffic is coming from. So ideally, I would read the address, search the other index for the company, then store the company alongside the original address.
Can this be performed at all, so far I've only seen accessing fields in a self-contained index?
