Depending on your system configuration, it’s necessary a minimum number of keywords, this amount may vary according to each journal. To add the keyword, type on the search field at least 3 letters of the word and then click the button “Find keywords”, a list will appear showing the options. If the word you want isn’t on the list, a link will be given for you to add a new one. In some cases, to add new keywords, you will need to contact the journal’s secretariat requesting to add it on the list.
NOTE: Add new keywords one by one. Don’t paste or type multiple keywords or the system will treat them as a single word.
