| 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.

| smith$.au. retrieves all authors with last name beginning with Smith (Smith, Smithson), including compound last name Smith-... smith $.au. smith t.au. smith t$1.au. smith t$.au. smith $.au. |
|
drowning.ti. drowning.ab. drown$2.ti. drown$.ti. cold water drowning.tw. |
|
|
| jama.jn. retrieves all articles with JAMA as journal name heart & lung.jn. obstetrics.jw. nurse$1.jw. gynecol$.jw. |
|
|
| 26.vo. retrieves all articles in volume 26 of any journal 5.ip. 725.pg. |

|
| 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).

| 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). |
