Pubmed Filters

Question

[d.caliano]

Hi,

For pubmed search, I know there's a filter called free full text [sb] that allows you to get only free full text articles. But my question is:

Is there a filter to get only articles which are not free?

If I write NOT free full text[sb] the term not is ignored because is not recognized. So is there another way, or another filter?

Thanks for your attention

I suppose you could always do two queries: one for all articles, and one for all articles that are free full text. A quick non-intersection will get you those that are not free full text.
