To convert your advanced search to an expert one, click Switch to expert mode.
The expert search page will be displayed containing the search criteria you already entered on the advanced search page.
Expert search allows you to use all available search fields, in any combination you choose, by using the common command language (CCL).
You can enter criteria with strict syntax rules in the search field, to run a highly specific search. You can also narrow down your searches using a variety of structured commands, which can restrict your query to specific targeted documents.
The format of syntax used by TED is the following:
XX = [value]
XX is the code or the abbreviation of the search field, comprising 2 letters. The value can be 1 character or a string of characters, a date, a range of numbers, or simply a wildcard.
