Finding free full text articles in PubMed

PubMed Central provides access to journals that provide free full text articles but did you know that a better way to get free full text articles is by using PubMed's "Search Field Descriptions and Tags"?

Enter search terms as usual in PubMed
and add (exactly as shown): AND Free Full Text [Filter]

Try this search:
transfusion AND platelets AND 2004:2005[dp] AND English[la] AND Free Full Text [Filter]
