When reviewing on a topic spelt differently based on US or UK system like above is it necessary to do a search with only one style or do we search by both styles of spellings?
I think the language of the submitted articles should comply the language style of the particular Journal (mentioned in the Instructions for the Authors). It helps the reviewers and the readerships as well.
Leaving either one method of spelling means leaving philosophies, thinkers and ideas originating from authors who follow the particular style of spelling.
