Perhaps you should try some spelling variations:
global equivalence » local equivalence, logical equivalence, formal equivalence
global reference » global conference, global relevance, regional reference
global presence » global existence
from genes » from gene, from general
antibiotic » antibiotics

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( antibiotic resistance : from genes to global equivalence ) OR ((( antibiotic resistance : from genes to global presence ) OR ( antibiotic resistance : from genes to global reference )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( antibiotic resistance : from genes to global equivalence ) or ((( antibiotic resistance : from genes to global presence ) OR ( antibiotic resistance : from genes to global reference ))))".
• Adding a wildcard symbol may retrieve word variants: (( antibiotic resistance : from genes to global equivalence ) or ((( antibiotic resistance : from genes to global presence ) OR ( antibiotic resistance : from genes to global reference ))))*.
