Basic search (easy one):
put all the keywords you can think of in one filed and search within "All fields". Back to search page.
Advanced search: Search keywords within specific fileds (author, title, etc..).
Notice: Please do not include any stopwords in your keywords when you are searching within specific fields.
Please break a sentence into several pieces by the stopwords, and use one of the pieces.
For example, if you want to search an article with the title "Training strategies for laboratory animal veterinarians: challenges and opportunities", the possible keywords you can use are: "Training strategies", "laboratory animal veterinarians: challenges", and "opportunities". Of course you can also use their subset, such as "Traning", "laboratory", "animal" etc.
