Conseils de recherche

 

Familiarisez-vous avec les fonctions de recherche du système et apprenez comment utiliser les caractères spéciaux et les opérateurs pour améliorer votre recherche.


Recherche par défaut - Linguistique

VALEURS PAR DÉFAUT :

  • 2 mots ou plus séparés par des espaces tels que des advertising campaigns sont recherchés avec un AND implicite.
  • Mettre les mots entre guillemets (""") pour rechercher des expressions exactes. ex "advertising campaigns"

LES PARAMÈTRES PAR DÉFAUT QUI PEUVENT ÊTRE MODIFIÉS :​

  • Si un champ spécifique n'est pas saisi avec une requête de recherche, la valeur par défaut est de rechercher dans Tous les champs+ texte (tous les champs indexés du document complet plus le texte intégral ProQuest) ou Tous les champs (sans texte intégral) (tous les champs indexés du document complet, mais sans inclure le texte intégral).
  • LINGUISTIQUES 1 - Les variantes orthographiques permettent au moteur de recherche de reconnaître et de faire correspondre les différences d'orthographe entre les versions américaine et britannique d'un mot donné, comme humor vs. humour. Si vous ne souhaitez pas que des variantes orthographiques soient appliquées à votre recherche, saisissez votre terme entre guillemets " ".
  • LINGUISTIQUES 2 - La lemmatisation permet au moteur de recherche de reconnaître et de faire correspondre différentes formes grammaticales d'un mot telles que les pluriels et les adjectifs. Par exemple, la recherche de mouse produira également des résultats sur mice. Rechercher sur tall  produira également des résultats sur tallest. Si vous ne souhaitez pas que la lemmatisation s'applique à votre recherche, saisissez votre terme entre guillemets " ".

    Ces valeurs par défaut peuvent être contrôlées par votre administrateur ProQuest. Les utilisateurs accédant à Mon Compte peuvent également modifier ces paramètres dans la section Préférences de votre compte "Mon Compte". Veuillez consulter la section "Mon Compte" (My Research) de ce guide pour plus d'informations sur la création d'un compte et la modification des préférences.

Boolean Operators

  boolean "AND" diagram    AND

Use AND to narrow a search and retrieve records containing all of the words it separates, e.g. adolescents AND children  will only find records containing both these words.


 

 boolean "OR" diagram     OR

 

Use OR to broaden a search and retrieve records containing any of the words it separates, e.g.adolescents OR children  will find records containing adolescents only, children only, or both words.


 boolean "NOT" diagram   NOT

Use NOT to narrow a search and retrieve records that do not contain the term following it, e.g. adolescents NOT children will find records that contain adolescents, but will not contain the word children.

Truncation, Wildcard, and Hyphen Characters

  

 

   *

 

The asterisk (*) is the Truncation character, used to replace one or more characters. The truncation character can be used at the end (right-hand truncation), or in the middle of a word. The maximum number of characters that will be retrieved is 5. 

Example: Searching for econom* will find economY, economICS, economICAL, etc.

Limited truncation: a number can be entered next to the asterisk to define how extensive the truncation should be. The max number supported is 20. This way the default limit of max 5 characters can be overcome.

Example: econom[*2] will find economY, economIC  but not economIST, i.e. will replace up to 2 characters only

An asterisk can also be used within the double quotes to account for the retrieval of plurals, for example. 

Example: "economic value*" can help retrieving also the plural "economic values"

(Please note: Exact quotes plus the truncation on a single word don’t work.

With "econom*" the truncation won’t execute). 

    ?

 

The question mark symbol (?) is the Wildcard character, used to replace any single character, either inside or at the right end of the word.  One single ? will retrieve only one more character, ?? won't retrieve less than 2 more characters, etc.

Example: Searching for t?re will find tire, tyre, tore, etc.

   -

Use a hyphen to indicate a range when searching numerical fields, such as Publication date.

Example: YR(2005-2008)

   <

   >

Use the less than or greater than symbols to indicate before/after or smaller/larger or less/more when searching numerical fields, such as the Publication date.

Example: YR(>2008) will located documents published after 2008

 

*Note: When using the asterisk (*) or wildcard (?) in your search, any terms retrieved using either of these are not considered when sorting your results based on relevance. This is because there is no way for ProQuest to assess the relevance of these terms to your research as the term itself is not exact. For example, your search on 'bio*' could return occurrences of any of all of these terms: 'bionic' or 'biosynthesis' or 'biodegrade' or 'biographic.' One, some, all, or none could be relevant to your search. 

Proximity Operators

Proximity and adjacency operators are used to broaden and narrow your search.

  

     NEAR/#
         n/#

Finds documents where the search terms are separated by up to a certain number of words of each other (either before or after).   Note: If you don't specify a number after the slash, NEAR will default to maximum 4 intervening words between terms

Example: computer NEAR/3 careers                

                computer and careers can be separated by up to 3 intervening words

                retrieves        career in the computer industry

  

      PRE/#
         p/#

Finds documents where the search terms are separated by up to a certain number of words of each other in the specified order.    Note: If you don't specify a number after the slash, PRE will apply a default value of max 4 intervening words .

Example: "business management" PRE education    =  "business management" PRE/4 education

               "pre" p/1 war      retrieves pre-war   but also   pre-world-war         

(Note: to search PRE or NEAR as search terms, put them between quotes.)

 

     EXACT
         .e

Used primarily for searching specific fields, like Subject, EXACT looks for your exact search term in its entirety, rather than as part of a larger term.

Example: EXACT(“higher education”) in the Subject field            SU.EXACT(“higher education”)
will retrieve documents with the subject term "higher education".
Will not retrieve:documents with the subject terms “higher education administration”, “women in higher education”, etc.

Operator Precedence

ProQuest assumes your search terms should be combined in a certain order. If you include operators such as AND and OR in the same search string, they will be processed in this order:

PRE, NEAR AND, OR, NOT.

For instance, in a search on education AND elementary NOT secondary the combination education AND elementary is considered first, which is correct. This search will return results regarding education with information on elementary but not secondary level.

Parentheses can be used to control the order in which the search terms are combined, when the standard operator precedence would retrieve unintended results.

An example why parentheses are important: Searching for:  

dog OR cat AND food OR nutrition

will retrieve a certain number of documents which contain both CAT and FOOD, plus a certain number of documents which may contain either DOG or NUTRITION alone, thus including several potentially irrelevant documents

Considering the precedence order, the above search will be processed this way:      

dog OR (cat AND food) OR nutrition

In order to get the intended results, i.e. documents that contain either DOG or CAT, but also must contain either FOOD or NUTRITION, in any combination, use the parentheses to change the order:

(dog or cat) AND (food or nutrition)
