With Sofia, you can use different types of operators to define, as accurately possible, your search criteria and language.
These operators apply to basic searches and advanced searches.
Boolean operators (ET/AND/+, OU/OR, SAUF/NOT/-)
Boolean operators are inserted between keywords in a search box or between search boxes to connect or exclude certain words or phrases.
For Sofia to recognize them, Boolean operators must be UPPERCASE, in French or English.
Keywords and their Boolean operators are processed left to right.
Narrows search results by returning only items that include both words/phrases connected through the operator.
* If no other operator is entered in the search box, a Boolean AND is by default inserted between the words.
|OU/OR||Broadens search results by returning items that include either word/phrase connected through the operator.
Example: cellular OR smartphone
|SAUF/NOT/-||Reduces search results by excluding items that include the word/phrase after the operator.
Example: “renewable energy” EXCEPT hydroelectricity

Use English quotation marks (“ ”)to find an exact phrase or the closest words.
An asterisk (*) isolates the root of a word to include all variations or words from the same family. This generally increases search results. At least three letters must precede the asterisk.
A pound sign (#) or question mark (?) substitutes one or several variable letters in a word. Masks broaden search results. At least three characters must precede the mask.
The pound sign (#) substitutes only one letter.
The question mark substitutes several letters (9 maximum).

Specify the order in which Boolean operators are applied to group keywords. Once the search is launched, Sofia interprets the words and operators in brackets first, and interprets the words and operators outside the brackets last.
Most search indexes are displayed in the advanced search window, but you can also enter their abbreviations in the in search boxes (basic or advanced search), and combine them with different operators.
The following list includes the most commonly used indexes and their abbreviations:
*Please note that a colon (:) after an abbreviation launches a keyword search in the index, but the equal sign (=) is used to find a specific phrase in the index. In the latter case, the phrase must be located at the beginning of the field in question, without any words after, which significantly narrows results. When in doubt, use a colon with quotation marks. Ex.: kw:“early childhood” As such:
means that we’re looking for documents precisely entitled “Early Childhood”. A document entitled “Early Childhood : A Survey of Best Practices” would therefore not be included in the search results.
searches for the phrase « early childhood » wherever it may be within the title field, even in combination with other words.

Do not use spaces between index abbreviations and punctuation marks ( : or =), or between punctuation marks and keywords. Ex. : au=shakespeare william
