I would like to find out the total number of publications in the Web of Science. (Actually, I'm interested in certain subcategories over time, but not restricted by word content at all. The categories and years can be accessed after doing the primary search).
What is the most general possible matching string / syntax?
My best idea so far is using
in the advanced search. This is obviously not perfect. I tried to combine something like
x OR NOT x but those get rejected.
There is a related question here: Global number of publications over time to which one could give more up to date data based on this question.
