// Search for status updates and just pass the Tweet along (no special mapping required like FacebookPost{} because the Tweet struct is used across multiple API calls unlike Facebook)
// All "search" functions (and anything that gets data from an API) will now normalize the data, mapping it to a Social Harvest struct.
// This means there will be no way to get the original data from the service (back in the main app or from any other Go package that imports the harvester).
// This is fine because if someone wanted the original data, they could use packages like anaconda directly.
// What happens now is all data pulled from earch service's API will be sent to a channel (the harvester observer). However, this function should NOT be called in a go-subroutine though.
// We don't want to make multiple API calls in parallel (rate limits).
// NOTE: The number of items sent to the observer will be returned along with the last message's time and id. The main package can record this in the harvest logs/table.
// The harvester will not keep track of this information itself. Its only job is to gather data, send it to the channel and report back on how much was sent (and the last id/time). Period.
// It doens't care if the data is stored in a database, logged, or streamed out from an API. It just harvests and sends without looking or caring.
// Whereas previously it would be doing the db calls and logging, etc. This has now all been taken care of with the observer. All of these other processes simply subscribe and listen.
//
// Always passed in first (always): the territory name, and the position in the harvest (HarvestState) ... the rest are going to vary based on the API but typically are the query and options
// @return options(for pagination), count of items, last id, last time.
