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

"a statistically significant decrease in the plasma L-ascorbic acid concentration "

  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 anticancer and vitamin K

"Inhibition of rat liver regeneration after partial hepatectomy and induction of ERK phosphorylation by Cpd 5, a K vitamin-based anticancer compound. "

  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

"while twitchin and myorod appeared at the blastula stage (12 h after fertilization).

  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

"Early ovarian carcinoma.....Surgical and drug therapy"

  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.
CheckTags
 

CheckTags are frequently searched terms that have been identified to bypass the mapping screen to help the searcher get to the results faster. Emcare checktags terms includes the following:

Priority Journal Article
Newborn Human
Infant Nonhuman
Adolescent Letter
Adult Clinical Article
Aged Controlled Study
Age Note
Child Case Report
Male Major Clinical Study
Female  
Defined Adjacency (ADJn) x ADJn y patterning adj3 embryo  

"Nodal signalling are all critical for proper patterning of the vertebrate embryo"

  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=2

"To test this hypothesis, lactate concentrations in the whole blood, plasma and red blood cells of AS and AA were compared at rest "

  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$

"OBJECTIVE. To investigate apoptotic, degenerative, and inflammatory changes occurring in the cervical intervertebral discs of rats."

  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

"an intravascular ultrasound (IVUS) probe was placed in LCx in 29 dogs."
"and the response to HFS was blunted in one dog (10-11 V)."

  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

"Inflammatory activity and anticardiolipin antibodies during tibolone treatment of healthy postmenopausal women. "
"We report the computed tomography features of a woman..."

  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

" one or more colours (95.5%)"
"in addition to the predictable red hair color (RHC) alleles"

  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... "

"n" "3".vo

"Foodborne Pathogens & Disease. Vol. 3(2)(pp 212-215), 2006. "

 

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.

Stopwords
The Ovid search engine applies so called "run-time stopword processing". This means the search engine on the fly ignores the stopwords: and, as, by, for, from, in, is, of, on, that, the, this, to, was, were & with.

Therefore a search: at risk for diabetes.ti will also find: at risk of diabetes. The distance of one word in between is kept, but the stopword "for" is ignored.

Special Ovid Filters for Emcare

Sentence Syntax: limit 1 to Adverse Effects - focussed
limit 2 to Children
 

You can use Special Ovid Filters to restrict retrieval to a pre-defined set of records, populated by a special Ovid search strategy for that topic. As the results sets for these filters are created with every database update, the results display quickly. Ovid filters are “AND” combined with the search line you are trying to limit, unless stated otherwise (e.g. humans only).

Each of the search hedges below are based on publicly available filters that have been reviewed, translated and improved by Ovid expert searchers. While these filters aren’t validated by Ovid, we provide the full transcript for each filter below and we have placed a reference for each filter where applicable. You may want to review the underlying terms and modify them as necessary. Ovid welcomes your suggestions to enhance the filters; to provide feedback and ideas for the Special Ovid Filters, please contact support@ovid.com.
