Ovid Database Information: Tips and Tricks
The following tips are helpful when using OVID databases to verify incomplete or incorrect references, search for specific words and phrases, and combining different subjects/topics. These searches are done on the main search screen (i.e. do not click on any buttons before entering the search). NOTE: all field tags MUST have a period both before AND after the tag.
For additional information on field searching see 
Searching Fields in Ovid Databases

Combining Searches
Any type of search can be combined with any other type of search, even another of the same kind, such as two author names. Use set numbers (1 and 2) or put multiple commands on the same line (smith-t$.au. and jama.jn.). To include two or more terms as synonyms, use OR (measles or rubella). To eliminate the results of one set from an overlapping set, use NOT (2 not 1; measles not rubella).

Truncation Symbols
Truncation allows for different word endings or spellings.

$
means any number of characters following (including 0 characters)

$n
where n is a number means UP TO n characters following

:
means ANY NUMBER of characters following

:n
where n is a number means UP TO n characters following

#
means one character and is usually used inside a word to account for variations of a word (wom#n = woman OR women). # can also be used at
the end of a word to indicate one more character follows (isolate# = isolates OR isolated but NOT isolate)

?
is used inside a word to account for variations in spelling (labo?r = British labour OR American labor)

Other Shortcuts
To explode a known Subject Heading, type EXP before the term (exp eye diseases). This will only work for valid Subject Headings in databases that use hierarchically arranged headings; it will not work for textword searching. Exploding means that all narrower related terms will be included in a Subject Heading search (exploding heart diseases means either the term heart diseases or at least one specific heart disease, such as endocarditis, must appear in each item retrieved).

To add specific subheadings, in databases that use them, to a search term, type the appropriate two letter code(s) after the forward slash ( / ) following a Subject Heading (eye diseases/dt -- drug therapy of eye diseases). Separate multiple codes with commas. To remove subheadings from an existing search, type the set number followed by a forward slash (2/).

To focus an existing search statement so that the term is one of the main points of the article, type an asterisk ( * ) before the set number (*1).  This only works if the search statement contains a single Subject Heading and the focus function is allowed in the database.

To delete selected lines from a search strategy, type ..PG followed by the set numbers to delete (..pg 1-3; ..pg 1,3,5-7).

To print just the search strategy, type ..PS (in the Web interface, then use the Print button on the browser to print the new page that displays only the strategy).
