Search operators

The basic search operators are:

AND (default) lithium AND battery both terms must occur
 OR  lithium OR battery one term must occur
NOT lithium NOT battery
results with "battery" will be excluded
lithium -battery  same as NOT


Other operators are available to help build a more complex query:

grouping: () (lithium AND battery)
exact phrase: ""  "lithium battery"
proximity: ~n (to be used in conjunction with "") "lithium battery"~2
truncation: multiple characters: * batter* 


Fields available are:

  • title
  • abstract
  • author
  • journal
  • keywords
  • year

The search operators can be used in fielded searches:

title:"lithium battery"~2 AND author:Wan*
