Truncation and Wildcards:

Offers a way to easily search for words with multiple endings or within words or word groups.

• Any terms retrieved using either truncation or wildcard characters are not considered when sorting your results based on relevance.

CINAHL: (*/?/#)

• The asterisk (*) matches multiple characters
  • use either at the end of words or within words
    • e.g. nurs* finds nurse, nurses, nursed, nursing, nursery, etc.
    • e.g. equ*y finds equity, equitability, equality, equally
  • use between words to match a single word
    • e.g. nursing * education finds nursing education, nursing diabetes education, nursing and education
• The hash sign (#) matches one optional character.
  • use where an alternate spelling might contain an extra letter
    • e.g. orthop#edic finds orthopedic, orthopaedic
• The question mark (?) matches exactly one character.
  • use to replace a letter
    • e.g. Wom?n finds women or woman; Assistan?? finds assistance or assistants
  • cannot be used as the first character of a search term
    • e.g. ?ffect
• truncation and wildcards can be combined in a search term
  • e.g. p#ediatric* finds pediatric pediatrics pediatrician pediatricians paediatric paediatrics paediatrician paediatricians

PubMed: (*)

• Asterisk (*) matches multiple characters - substitute for 0 or more characters in a term or phrase.
  • Search for variant word endings
    • e.g.  mimic* finds mimic, mimics, mimicking, etc.
  • Use within words to find multiple variant characters
    • must have at least 4 characters before the wildcard
      • e.g. equ*y finds equity, equitability, equality, equally
  • Terms can contain multiple wildcards:
    • e.g. organi*tion*

ProQuest: (*/?)

• An asterisk (*) matches up to 5 characters
  • cannot be used as the first character of a search term
    • e.g. *ffect
  • Search for variant word endings
    • e.g.  nurs* finds nurse, nurses, nursed, nursing, nursery, etc.
  • Use within words to find multiple variant characters
    • e.g. equ*y finds equity, equitability, equality, equally
  • [*n] denotes up to how many characters you want to truncate
    • e.g. nutr[*5] finds nutrition, nutrient, nutrients
• The question mark (?) matches exactly one character. The ? will match both 0 and 1 character
  • e.g. Wom?n finds women or woman; Assistan?? finds assistance or assistants

                                                             

Place phrases in Quotations Marks

• can use in CINAHL, PubMed, and ProQuest
• e.g. “Health expenditures” or “intensive care unit” or "Calgary Family Assessment"

Caveat: Turns off auto mapping and auto explode in PubMed

Proximity searching allows for searching for two or more terms within a certain number of words of each other.

Near:

Use N# or N/# or NEAR/# if the words can appear in any order

CINAHL: (N#)

• e.g. N3 finds the words if they are a max of 3 words apart from one another, regardless of the order in which they appear.

• insurance N3 reimbursement will find results like:

  • insurance reimbursement

  • insurance for reimbursement

  • reimbursement practices of insurance companies

  • insurance approval and reimbursement

ProQuest: (N/# or NEAR/#)

• ProQuest searching works the same as CINAHL but the symbols are different.
• e.g. insurance N/3 reimbursement
• insurance NEAR/3 reimbursement

Within or PRE:

Use W# or PRE/p if you want the words in a specific order

CINAHL: (W#)

• e.g. W4 finds words that are within 4 words of one another, in the order entered.
• Covid W4 protocols will find results like those below but will not find protocols for Covid

  • COVID-19 pandemic and public health protocols

  • COVID-19 related protocols

ProQuest: (PRE/# or P/#)

• ProQuest searching works the same as CINAHL but the symbols are different.
• e.g. Covid PRE/4 protocols
• Covid P/4 protocols

AND

• Use AND to indicate that all of the search terms must be present in an article. 
• Great way to get more specific results. 
• e.g. searching for Madonna AND church means that articles must contain the word madonna and the word church to show up in the results. 
  • For example, if the circle on the left represents articles containing the word Madonna, and the circle on the right includes articles containing the word church, the shaded area shows the results for a search for Madonna AND church

Madonna church

OR

• Use OR to indicate either of the terms should be included in the results. Use OR between synonyms or related terms

• e.g. a search for Madonna OR church would result in
  • articles that mention the word madonna but do not include the word church
  • any articles that include the word church but do not include the word madonna
  • articles that include both the word madonna and the word church

Madonna  church

 NOT

• Use NOT to exclude articles with a different meaning or an unwanted concept
• For example, if your results include articles on the Virgin Mary, when you are actually looking for articles on the singer Madonna, search for Madonna NOT Virgin Mary to exclude them. (Be careful, may also exclude any articles dealing with the relationship between the singer and the church.)

Madonna  Virgin Mary

Not enough (or any) articles on your topic? 

Here are some tips to find more results:

• Check spelling
• Use synonyms or related words
  • e.g. ethics OR morals OR principles
• Use truncation
• Search for broader, less-specific terms
  • e.g. consider health care personnel rather than the more specific nurses
• Expand date range if possible

Too many results?  Or results not focused on your topic?

• Try a subject search instead of a keyword search

• Limit your keyword search to the abstract or title

• Try Phrase searching

• Add terms to your search using the Boolean "AND" operator

• Try narrowing dates of publication
