General notes:
Common words such as 'the' and 'and' are not indexed, and therefore are not found if you search for them.
Uppercase and lowercase differences are ignored. Diacritics (accents) are ignored. Therefore, searching for any one of the following terms will find occurrences of all the terms: eglise, Eglise, église, Église.
English word stemming is applied (for example, 'paint' will find 'painting' and vice versa).
Punctuation:
Avoid using punctuation in your search terms. Instead of searching for notre-dame, search for notre dame (in basic searches); or notre AND dame (in advanced searches).
Basic search:
Enter one or more search terms separated by spaces. Each result must contain at least one of the search terms. Example: peter book. This will find all results containing 'peter' or 'book' (or both).
Advanced search:
Use uppercase AND, OR, NOT and parentheses to create more complex searches. Example: peter AND (sheep OR book). This means each result must contain 'peter' and must also contain either 'sheep' or 'book'.
Example: peter NOT paul will find those records which contain 'peter', but which do not contain 'paul'.
In the absence of parentheses, expressions are evaluated from left to right, so peter AND sheep OR book is equivalent to (peter AND sheep) OR book.
The advanced search peter OR sheep OR book is equivalent to the basic search peter sheep book.
Phrases:
Advanced search supports using phrases as search terms. A phrase is two or more words in double-quotes. Example: "holding an opened book". This will find the exact phrase, as well as variants such as "holds an open book".
