When a document is not available in English, it is presented in French or Spanish.

The search on authors' names applies only on names of written papers.

The search engine Pertimm ® operates only on the PDF files contained in the DVD.

Search is done by writing a word or several words (separated by a blank) in the search window.

Documents found at the end of the search are presented in two ways:

• a text-type version with the words used for the search highlighted in colour ;
• the PDF file of the document. In this case, it is necessary to use the search toll provided by Acrobat ® to locate, in the document, the terms used for the search.

The search engine also provides a list of expressions it found correlated to the searched term. A click on this expression directly leads to the list of documents which contain this expression.
