Advanced Searching
You can use special search syntax to combine search terms or strategically develop a search.
Operator Syntax Search Example Sample Results
OR x or y vitamin c or ascorbic acid

"oxidative DNA damage-mediated mutations inhibited by vitamin C"

 

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 depression and diet

"The interactive effect of dietary protein and vitamin levels on the depression of gonadal development in growing male rats kept under disturbed daily rhythm"

 

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 blastula not embryo

"Furthermore, we show that early blastula formation was disrupted by pharmacological blockade of IP3 receptors or phospholipase C"

 

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 drug adj therapy

"Patient information on drug therapy."

 

The Adjacent operator (ADJ) retrieves records with search terms next to each other. 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 diabetes adj3 monotherapy

"Clinical pharmacological study of mitiglinide in type 2 diabetes patients with voglibose monotherapy"

 

The defined adjacency operator (ADJn) retrieves records that contain search terms within a specified number (n) of words from each other in any order. To use the adjacency operator, separate your search terms with ADJ and a number from 1 to 99. For example, the search physician adj5 relationship retrieves records that contain the words physician and relationship within five words of each other in either direction. This particular search retrieves records containing such phrases as physician patient relationship, patient physician relationship, or relationship of the physician to the patient.
Frequency (FREQ) x.ab./FREQ=n blood.ab./freq=2

"we recorded continuous blood pressure, heart rate, finger skin blood flow and respiration frequency before (10 min), during (60 min) and after (30 min)"

 

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$

"tools to investigate substrate recognition"

 

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 : (colon). For example, in the truncated search disease$, Ovid retrieves the word disease as well as the words diseases, diseased, and more.
limited Truncation ($) x$n dog$1

"Hard ticks infesting dogs in Hungary and their infection with Babesia and Borrelia species"

 

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

"Hemoglobin A1c Predicts Diabetes but Not Cardiovascular Disease in Nondiabetic Women"

 

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

"A common neural substrate for perceiving and knowing about color"

 

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" "left/right"

"notably shifting patterns and hot/cold spots of relative risk"

"n" "3".vo

"La Rivista Italiana della Medicina di Laboratorio. Vol. 3(2)(pp 135), 2007."

 

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.

Abstract
  Two of the three adult dogs kept in a family developed severe gastroenteritis. From the feces of one 
  of the affected dogs a minute virus of canines (MVC) was detected by PCR and virus isolation. That this 
  virus had recently infected the dogs was indicated by high anti-MVC antibody titers of their sera. No 
  other virus commonly associated with canine gastrointestinal disease was implicated. As no previous 
  association of MVC infection and disease in aged dogs had been described, further characterization of 
  the isolated virus was performed to determine if it had unique pathogenic or genetic properties. 
  Experimental infection of adult dogs did not result in clinical disease and comparison of the viral 
  genome with other MVCs did not reveal any novel elements. The American, Japanese and Korean MVC 
  strains studied were closely related to bocaviruses of bovine and human origin, and appeared to have 
  evolved uniquely in the dog population after dividing from the common ancestor of bocaviruses. 
  Further detailed clinical and virological studies are warranted to define the role of MVCs in disease in 
  adult dogs. 2010 Elsevier B.V.

Title

Abstract
  Endogenous cannabinoid receptors are widely distributed throughout the CNS, including the 
  brainstem, and modulate a variety of functions, including breathing. In adult rats, activation of 
  cannabinoid 1 receptors has been shown to depress breathing. Here in neonatal mice, we used in 
  vitro electrophysiology, pharmacology, and immunohistochemistry to analyse the central effects of 
  the endocannabinoid anandamide (AEA) on the activity of the medullary respiratory rhythm generator 
  (RRG). First of all, in vitro electrophysiology on medullary preparations has revealed that bath 
  application of AEA (30 muM, 15 min) significantly depressed respiratory activity. Secondly, applying 
  pre-treatments with alpha-1 (Prazosin, 5 muM, 10 min) and alpha-2 (Yohimbine, 5 muM, 10 min) 
  adrenoceptor antagonists prior to AEA application abolished the AEA-induced depression of the RRG. 
  Finally, immunostaining revealed a dense network of fibres positive for the cannabinoid 1 receptor 
  in the ventrolateral medulla (VLM), a region known to contain both the RRG and the modulatory A1/C1 
  catecholaminergic group. Moreover, cannabinoid 1 receptor positive fibres were found in close 
  apposition with A1/C1 catecholaminergic cells, identified by the presence of tyrosine hydroxylase. 
  In regard of our electrophysiological, pharmacological and immunostaining results, we conclude that 
  AEA has a central depressive effect on the neonatal RRG, probably via the medullary A1/C1 catecholaminergic 
  neurons which are already known to modulate the respiratory rhythm generator. 2010 IBRO.
