The advanced search combines many different search fields including Keywords, Classifications, Assignees, Numbers, Molecules, Legal status and over 400 other sub fields.
Each field can be used alone or combined with another field to build complex Boolean queries. The buttons next to each field allow you to access more options for that field. More relevant help can also be accessed via the question marks on the search page.
Should you have any difficulty, please contact our Helpdesk by sending an email to help@questel.com to open a help ticket.
