Type .tw.  after your search term(s) e.g. dupixent .tw. This will search for the title (TI), abstract (AB) and the drug trade name (TN).

Type .ti. after your search term(s) e.g. dupixent .ti. This will search for references where your words appear in the title (TI) only. 

Type .ab. after your search term(s) e.g. dupixent .ab. This will search for references where your words appear in the abstract (AB) only

Type .ti,ab. after your search term(s) e.g. dupixent .ti,ab. This will search for references where your words appear in the title (TI) or abstract (AB).

Step 2. 

  • The box Map Term to Subject Heading is checked by default. Your search term will be mapped to the Subject Heading if you do not specify a particular search field to search (as in Step 1).
