You can enter the search query in the Search terms input field. The search syntax is the same of the official Pubmed site, and you can find it in the Pubmed help page. However, in MedASq it is possible to use the boolean operators AND, OR, NOT also in lowercase. The search field tags can be embedded both in square brackets, like in the original Pubmed, and in angle brackets < >, which sometimes could be easier to find on the keyboards of some handheld devices.
You can suggest me new features, or customized versions in other languages, by sending me a message from the email form in my home page.
