How to use ScienceDirect to find English literature? What I want to check is "heat transfer research of solar greenhouse maintenance structure", so how to input it?
Divide the search into several keywords, such as: solar greenhouse, maintenance structure, heat transfer,

The corresponding English name is: solar greenhouse, Maintain the structure, Heat transfer

1 Of course, you can paste these keywords directly into the search all fields box, and click on the magnifying glass to search, and the results will definitely be many.

2. You might as well use advanced search, because only two keywords can be added, so I use the first and third keywords to search only topics, abstracts or papers with these two keywords, as shown in the figure below:

After clicking search, several similar results appeared.

3. Because advanced search can only enter two keywords, if you want to enter more, you can also choose expert search.

You can control whether these keywords must be together, such as inputting "solar greenhouse" and maintaining structure and heat transfer.

Then the full text must contain the phrase solar greenhouse, and 6 1 results come out:

It can also input solar greenhouse, "maintenance structure" and heat transfer.

Or solar greenhouse and its maintenance structure and "heat transfer"

Even "solar greenhouse" and "maintenance structure" and heat transfer search.
