*

At the end of string of characters, retrieves all variations starting with that string; can also be used within words to find multiple characters, or between words to replace a single word

e.g. computer* retrieves computer, computers, computerised, etc.

? 

within a word to replace a single character

e.g. standardi?ed retrieves standardised or standardized

Note: Question marks at the end of a word are NOT treated as wildcards; they are automatically removed

#

within a word or at the end of a word to replace zero or one character

e.g. colo#r retrieves color, colour

“ “

Finds exact expression; by default, CINAHL will search for keywords in the entered order even if no quotes are used

()

specifies the order of the search

e.g. (urban OR city) AND freshwater

Nn

Near operator

Retrieves records that contain your terms (in any order) with up to n words between them

e.g. (decision* N3 (aid* OR support*)) retrieves records that contain phrases with up to three words between decision and either aid* or support*, in either direction.

 

Wn

Within operator

Finds the words if they are within n words of one another and in the order in which you entered them.

e.g. primary W3 care finds records with phrases in which primary precedes care with three or fewer words between them.

 

Note: To use proximity operators in CINAHL, uncheck "Suggest Subject Headings" if entering an unqualified search (i.e., the default, if you have not selected specific fields to search) or specify the TI OR AB fields in your search query

e.g., TI (decision* N3 (aid* OR support* OR tool*)) OR AB (decision* N3 (aid* OR support* OR tool*))

Default "Select a field (optional)" (i.e., unqualified searching): Searches Title, abstract, subject headings

• Note: To execute unqualified searches properly, uncheck "Suggest Subject Headings"

Field codes should be capitalized

" "

Finds exact expression

e.g., "primary care"

 

You can also find an exact expression by specifying a search tag after the phrase

e.g., primary care[tw]

 

Or by using hyphens between the terms

e.g., primary-care

 

Truncated phrases without quotations, search tags, or hyphens:

 

In the older version of PubMed, searching occupational therap* (without search tags or quotations) would search for the variants of the phrase (e.g., occupational therapy / occupational therapies / occupational therapist / occupational therapists, but not "physical, occupational, and speech therapy", etc.); in the new version of PubMed, occupational therap* will map occupational to relevant MeSH terms and textword variants (or maybe not) then combine that search with AND with therap* variants in all fields: (((((("occupant"[All Fields] OR "occupant s"[All Fields]) OR "occupants"[All Fields]) OR "occupational"[All Fields]) OR "occupations"[MeSH Terms]) OR "occupations"[All Fields]) OR "occupation"[All Fields]) AND "therap*"[All Fields]

 

Note: Phrases may appear in a PubMed record but not be in the phrase index.

 

( )

Specifies the order of execution of the Boolean logic in the search

e.g., freshwater AND (urban OR city)

MeSH terms

Use quotes around MeSH terms to enforce their exact use

e.g., nursing[mesh] will search for "nursing"[mesh] OR "breast feeding"[mesh], while "nursing"[mesh] will only search for "nursing"[mesh] as a field of care

To explode/include narrower MeSH terms: " "[mesh]

PubMed automatically searches for records indexed with the the MeSH heading you are using as well as the more specific (narrower) terms beneath that heading in the MeSH hierarchy

e.g., "Health Services Accessibility"[mesh] will search for records indexed with "Health Services Accessibility"[mesh] OR "Health Equity"[mesh] OR "Right to Health"[mesh] OR "Universal Health Care"[mesh]

 

To turn off the Explode function: " "[mesh:noexp]

In the MeSH Database entry for the term of interest, check off Do not include MeSH terms found below this term in the MeSH hierarchy if you do not want to include narrower subject headings, or enter [mesh:noexp] after the MeSH term of interest

e.g., "Delivery of Health Care"[mesh:noexp]

 

Major topic: [majr]

Retrieves records for articles in which indexers consider your topic to be a main theme

To use this feature, in the MeSH Database entry for the term of interest, check off Restrict to MeSH Major Topic, or enter [majr] after the MeSH term of interest

e.g., "Delivery of Health Care"[majr] ([majr] can be combined with no exploding as well: "Delivery of Health Care"[majr:noexp])

Wildcards can be used anywhere in the word, even at the beginning

Note: Truncation does not disable lemmatization

*

Represents any number of characters, even 0

e.g., computer* retrieves computer OR computers OR computerised OR computerized etc.

? 

Represents any single character

e.g., wom?n retrieves woman OR women

" "

Finds words occurring in exact order as entered; can be combined with truncation and wildcards

e.g. "occupational therapy"

Note: quotes do not disable lemmatization

 

 

{ }

finds exact expression

• do not combine with truncation
• a hyphenated term within squiggly brackets can produce different results from a non-hyphenated term within squiggly brackets

Specifies the order of execution of the Boolean logic in the search

e.g., freshwater AND (urban OR city) 

 

PRE/n

Preceded by n

Retrieves articles that contains your words, in your given order, within a specified number (n) of words of each other

 e.g.  primary PRE/1 *care finds articles in which primary precedes care (or, as also relevant, healthcare) by one or fewer words

 W/n

Used by default in topic (TS) and title (TI) field searches; lemmatization and stemming are not used in combination with quotations or when search terms contain wildcards

To turn off lemmatization in new Web of Science: Go to Advanced Search > More options > Select Exact search

" "

Use straight quotes (NOT curly quotes) to finds words occurring in exact order as entered; can be combined with truncation and wildcards

e.g. "occupational therapy"

Note: Turns off lemmatization and synonym finder (what is lemmatization?)

 

()

Specifies the order of execution of the Boolean logic in the search

e.g., freshwater AND (urban OR city)

NEAR/n

Replaces the n with a number to specify the maximum number of words that separate the terms.

e.g., biologist NEAR/5 relationship

Finds articles in which biologist and relationship are no more than 5 terms apart

 

Note: You cannot use NEAR/n in between two sets of terms in which one set contains AND, even if implied: Be sure to enclose phrases in quotations as a result (because spaces between phrase words are otherwise treated as AND)

e.g., TS=((health care OR healthcare) NEAR/3 (setting* OR system*)) will not work because health care is interpreted as health AND care, but TS=(("health care" OR healthcare) NEAR/3 (setting* OR system*)) will
