This type of search is available under Publications tab inside databases. Use it if you want to search inside a specific journal. You can search alphabetically by title (if you know it) or by subject and description.
For example, to find out which publications on environmental science are available in a database, type in “environmental”. This search will retrieve all journals that have this word in their titles and descriptions. Such as: Environmental Conservation.
Publications search works better with one-word broad searches. You can add more specific terms later when you search inside the journal. Click in the journal title and then on the link "Search within this publication".
