The search also finds parts of words, so if you search for musiken you will also find drottningholmsmusiken, golovinmusiken and kröningsmusiken. Read under "exact words" below how to avoid this. Upper/lower case is not important, so SINFONIA, sinfonia and Sinfonia will all find the same texts.
Normally all pages where all your search words appear will be shown. You do not have to write a plus sign between the words. If you search for sinfonia e-moll you will only find pages where both these words appear.
To search for a phrase, enclose it in quotes " ". If you search for "BeRI 31" you will only find pages containing this exact phrase, but not those where both words occur but separated, e.g. "BeRI 40; Ro 31".
You can also use a minus sign - before a word to exclude it from the search. If you search for "sinfonia -ouverture -introduzzione" you will find pages where the word sinfonia occurs, but exclude those where the words ouverture and introduzzione occur.
To search for whole words, not parts of words, you can use an equals sign = before the word. To find BeRI 30 but not BeRI 301 write ="BeRI 30" in the search box.
