| You can use special search syntax listed below to combine search terms or strategically develop a search. Full documentation is provided in the Advanced Searching Techniques section of the Online Help. |
| Operator |
Syntax |
Search Example |
Sample Results |
| OR |
x or y |
vitamin c or ascorbic acid |
"dietary citrus bioflavonoid and/or ascorbic acid supplementation" |
|
The OR operator retrieves records that contain any or all of the search terms. For example, the search heart attack or myocardial infarction retrieves results that contain the terms heart attack, myocardial infarction or both terms; results are all inclusive. You can use the OR operator in both unqualified searches and searches applied to a specific field. |
| AND |
x and y |
cluster and migraine |
"Divalproex sodium in the treatment of migraine and cluster headaches" |
|
The AND operator retrieves only those records that include all of the search terms. For example, the search blood pressure and stroke retrieves results that contain the term blood pressure and the term stroke together in the same record; results are exclusive of records that do not contain both of these terms.
You can use the AND operator in both unqualified searches and searches applied to a specific field. |
| NOT |
x not y |
headache not migraine |
"The acupuncture randomised trial (ART) for tension-type headache" |
|
The NOT operator retrieves records that contain the first search term and excludes the second search term. For example, the search health reform not health maintenance organizations retrieves only those records that contain the term health reform but excludes the term health maintenance organizations. In this way, you can use the NOT operator to restrict results to a specific topic.
You can use the NOT operator in both unqualified searches and searches applied to a specific field. |
| Adjacency (ADJ) |
x y |
bone spur |
"Effects of acetic acid iontophoresis on heel spur reabsorption" |
|
The Adjacent operator (ADJ) retrieves records with search terms next to each other in that specific order. You do not need to separate search terms manually by inserting ADJ between them, because when you separate terms with a space on the command line, Ovid automatically searches for the terms adjacent to one another. For example, the search blood pressure is identical to the search blood adj pressure. |
| Defined Adjacency (ADJn) |
x ADJn y |
melatonin adj3 migraine |
"The therapeutic potential of melatonin in migraines and other headache types" |
|
The defined adjacency operator (ADJn) retrieves records that contain search terms within a specified number (n-1) of words from each other in any order (stop-words included). To use the adjacency operator, separate your search terms with ADJ and a number from 1 to 99 as explained below:
ADJ1 Next to each other, in any order
ADJ2 Next to each other, in any order, up to 1 word in between
ADJ3 Next to each other, in any order, up to 2 words in between
ADJ99 Next to each other, in any order, up to 98 words in between
For example, the search physician adj5 relationship retrieves records that contain the words physician and relationship with a maximum of four words in between in either direction. This particular search retrieves records containing such phrases as physician patient relationship, patient physician relationship, or relationship between cancer patient and physician.
Please note Ovid’s order of operation handles terms within parentheses first. Therefore it is recommended to apply the ADJn operator in one-on-one operations to avoid missing out on results. E.g. stroke adj4 (blood pressure or high blood pressure) could potentially miss out on some combinations of stroke with high blood pressure. The optimum way to execute this on Ovid is: (stroke adj4 blood pressure) OR (stroke adj4 high blood pressure). |
| Frequency (FREQ) |
x.ab./FREQ=n |
blood.ab. /freq=5 |
"Effects of Swedish massage on blood pressure" |
|
The frequency operator (FREQ) lets you specify a threshold of occurrence of a term in the records retrieved from your search. Records containing your search term are retrieved only if the term occurs at least the specified (n) number of times. In general, records that contain many instances of your search term are more relevant than records that contain fewer instances. The frequency operator is particularly useful when searching a text field, such as Abstract or Full Text, for a common word or phrase. |
| Unlimited Truncation ($) |
x$ |
rat$ |
"Comparative evaluation of hepatoprotective activity of carotenoids of microalgae" |
|
Unlimited
truncation retrieves all possible suffix variations of the root word
indicated. To apply unlimited truncation to a term, type the root word
or phrase followed by either of the truncation characters: $ (dollar sign) or * (asterisk). For example, in the truncated search rat*, Ovid retrieves the word rat as well as the words rats, and more. |
| Limited Truncation ($) |
x$n |
dog$1 |
"Learning from Dogis and Mystical Dogs" |
|
Limited truncation specifies a maximum number of characters that may follow the root word or phrase. For example, the truncated search dog$1 retrieves results with the words dog and dogs; but it does not retrieve results with the word dogma. |
| Mandated Wildcard (#) |
xx#y |
wom#n |
"Managing a young woman with cystic fibrosis" |
|
Searching with a mandated wildcard retrieves all possible variations of a word in which the wildcard is present in the specified place. You can use it at the end of a term to limit results to only those that contain the word plus the mandated character. For example, the search dog# retrieves results that contain the word dogs, but not those that contain the word dog, effectively limiting results to only those that contain the plural form of the word. The mandated wild card character (#) is also useful for retrieving specialized plural forms of a word. For example, the search wom#n retrieves results that contain both woman and women. You can use multiple wild cards in a single query word. |
| Optional Wildcard (?) |
xx?y |
colo?r |
"Non-random associations of graphemes to colours in synaesthetic and non-synaesthetic populations" |
|
The optional wild card character (?) can be used within or at the end of a search term to substitute for one or no characters. This wild card is useful for retrieving documents with British and American word variants since it specifies that you want retrieval whether or not the extra character is present. For example, the optional wild card search colo?r retrieves results that contain the words color or colour. You can use multiple wild cards in a single query word. |
| Literal String ("") |
"x / y" |
"Heat / Cold Application" |
"Patient education, psychological support, weight control, exercise, heat/cold application, and use of assistive devices are safe nonpharmacologic approaches." |
| "n" |
"3".vo |
"Phytotherapie 2005 Apr;3(2):72-6."
|
|
Quotation marks can be used to retrieve records that contain literal strings,
when the string includes special characters, such as a forward slash (/).
Quotation marks can also be used to retrieve records that contain numbers
that may otherwise be confused for earlier searches. In the example, a
search for 3.vo would limit the string from your third search in your search
history to the volume field. By including the number in quotation marks,
the search will retrieve documents with a 3 in the volume number. |
