Searching ProQuest Platform

     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.

     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.

   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.

ProQuest assumes your search terms should be combined in a certain order. If you include operators such as AND and OR, we will combine them in this order: NEAR, PRE, AND, OR, NOT.

For instance, a search on education AND elementary NOT secondary would be interpreted as (education AND elementary) NOT secondary. So in this case, (education AND elementary) is considered first.

This search will return results regarding education with information on elementary but not secondary education.You can also use parentheses to control the order in which your search terms get combined, instead of using the standard operator precedence.The use of parentheses and Boolean operators in combination is perfectly acceptable.

There are no stop words within the ProQuest platform. However, the natural language processing used by the search engine will naturally filter out certain “overabundant” words as being irrelevant.  While the number of times a term appears within a document does increase its relevance, this only works up to a certain point, at which time its relevance begins to decrease.

• Use quotation marks (“”) to search for exact phrases.
• Two word queries such as advertising campaigns are searched as an implicit AND
• Use search characters and operators to focus queries.
• If a specific field is not entered with a search query, the default is to search Anywhere (all indexed fields of the full record plus the full-text from ProQuest) or Anywhere except full text (NOFT) (all indexed fields of the full record, but not including the full-text). This default is determined by your ProQuest administrator and the preference can also be chosen in the account preferences section of your My Research account. Please see the My Research section of this guide for additional information on creating a My Research account and changing preferences.
• Spelling variants enable the search engine to recognize and match differences in spelling between American and British versions of a given word such as humor vs. humour. If you do not want spelling variants to be applied to your search, enter your term in quotation marks " ". This default is determined by your ProQuest administrator and the preference can also be chosen in the account preferences section of your My Research account. Please see the My Research section of this guide for additional information on creating a My Research account and changing preferences.
• Lemmatization enables the search engine to recognize and match different grammatical forms of a word such as with plurals and adjectives. For example, searching for mouse will also produce hits on mice. Searching on tall will also produce hits on tallest. If you do not want Lemmatization to be applied to your search, enter your term in quotation marks " ". This default is determined by your ProQuest administrator and the preference can also be chosen in the account preferences section of your My Research account. Please see the My Research section of this guide for additional information on creating a My Research account and changing preferences.

*Note: When using the asterisk (*) or wildcard (?) in your search, any terms retrieved using either or thesese 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 and adjacency operators are used to broaden and narrow your search.
