You can submit a keyword search against the following five categories:
- Anywhere: searches a combination of article title, abstract, journal title, assigned keywords, and authors.
- Subject: searches a combination of article title, abstract, and assigned keywords.
- Article title
- Journal title
A keyword search looks for terms anywhere within the specified indexed fields. By default, multiple words are searched as if there is the Boolean operator AND between the search terms. The system will retrieve items that contain each word. Items that only contain one of the words will not be retrieved. For example,
- water treatment --> retrieves items that contain the word water
and also the word treatment. The words do not have to be
side-by-side or in the same index.
You can use combinations of phrases, truncation and boolean operators to better define your search terms.
A phrase search will retrieve items that contain the words side-by-side. To submit a phrase search, enclose your search terms in quotation marks. The quotation marks will stop the system from trying a Boolean search.
"water treatment" --> retrieves only items that contain the phrase water treatment.
Use and to specify the presence of both terms.
Nanotechnology and plastic
Use or to specify the presence of either term.
Chemistry or chimie
1 character may be truncated internally or at the end of the word using a question mark.
Any number of characters may be truncated internally or at the end of the word using one asterisk.
Putting it all together
When using more than one operator, use parentheses to group strings.
Nanotechnolog* and (plastic* or polyester or aluminium)
Phrases can be used with boolean operators. Put quotes around a phrase that is included in a boolean search string.
"water treatment" or "traitement des eaux"
"water treatment" and "pollution control"
("water treatment" or "traitement des eaux") and "pollution control"
When using a combination of boolean operators and truncation, ensure that the truncated expression is listed first.
shear AND engineer
engineer* AND shear
shear AND engineer* will not work
polyester OR plastic* will not work
Searches against article title, abstract, journal title, assigned keywords, and author.
Use a combination of terms to obtain more relevant results.
Combine journal title and subject.
"electronic engineering" and electromechanical
Combine author's last name and subject.
Fletcher and proteins
Subject search uses a combination of terms found in the article title, abstract, and assigned keywords.
If you know a specific phrase in the abstract, title or subtitle of the article, enclose it within double quotes to find an exact match.
"algorithm combining ant colony optimization"
This function will yield the most results when searching on uncommon or unique words that could be found in the article. A space is the same as the Boolean operator AND.
If you know the title of the article enclose it within double quotes to find an exact match.
"Physical and genetic map of the Spiroplasma kunkelii CR2-3x chromosome"
Search on uncommon or unique words from the article title. A space is the same as the Boolean operator AND.
If you know the journal title, enclose it within double quotes to find an exact match.
"Canadian Journal of Chemistry"
Search on uncommon or unique words from the journal title. A space is the same as the Boolean operator AND.
Searching by author can be tricky because an author's name may be indexed many ways.
Fletcher, J. Murray
Enter the author's last name. This strategy retrieves the broadest search results possible. If several authors have the same name in the system, this search will retrieve publications from all similarly-named authors as well.
Search with the author's last name and first name or initial to refine your search.
Remember a space is the same as an AND between your terms.
The drop-down list in the search box relies on terms that appear in a journal or book's citation. As a name's format can vary from publisher to publisher, an author's name may appear in several different ways.
To search for more than one first name, use parentheses to group the first names together, then use "or" to indicate that you wish to find either name. To search for all first name variants, type the first letter of the name instead, followed by an asterisk.
Fletcher (John or Murray)
Fletcher (j* or m*)
To view all of an author's publications, use the "Browse by Author" tool. This feature displays all of an author's publications together under one name through the use of a unique identifier. This helps to avoid the ambiguity that can occur with keyword searches.
