To save an intermediate result, you could also use
some search | outputlookup temp.csv
and from here on start a new search with
| inputlookup temp.csv | continue search
If some search is a complex (time-consuming) search and you just want to play around with different ways of doing it in continue search, then this method will allow you to do so without any hassle. The only thing you may want to look out for is if the intermediate results are too numerous for a .csv file (say, some hundred thousand lines of result).
