Wherever appropriate, we have included tooltips to explain how to use a search field or a checkbox. Just hover your mouse over the "i". For example the tooltip for the search field "Case number" looks like this:
An example of the expected syntax is shown above the search field, on the right. The search engine is not case sensitive (i.e. it does not distinguish between lower case h and upper case H). The following example shows how an IPC code should be entered:
The collection contains documents in three languages: English, French and German. The search engine is tolerant regarding the use of diacritics. For example, it will accept "Partikelgroesse" and find documents with "Partikelgröße". Similarly, the search term "tete" will find documents containing "tête". The following table shows which diacritics can be replaced by which characters:
|Diacritics|| Replacement characters
You may get a better search service (for example, suggestions for other search terms) if you use the French search interface for French terms, the German search interface for German terms and the English search interface for English terms. You can switch interfaces by using the links "Deutsch English Français" at the top right of the page.
