Find Term
Use Find Term to type in a word or phrase and identify the correct Emtree subject term for it.
Type the word or phrase in the search box and click the Find button. (Quotation marks are not needed for multi-word phrases.) An alphabetical list of all terms containing the word(s) you typed appears, including both synonyms and preferred index terms.
(Note: Wildcard characters are not available for Find Term.)
Terms in normal black text are synonyms. Preferred Emtree terms are live blue links with a use: reference. For example, here the synonym myocardial infarction points to the correct Emtree term heart infarction.
Click on any blue Emtree term to see a tree display showing its position(s) in the Emtree thesaurus hierarchy. Here, clicking on heart infarction clearly shows its relationship to both broader disease categories (infarction, cardiovascular disease, necrosis, etc.) and narrower (more specific) infarction terms; in this case, heart infarction has several places in the tree – under infarction, ischemia, ischemic heart disease, etc. Narrower terms include acute heart infarction, Dressler syndrome, heart atrium infarction, silent myocardial infarction, etc. (These terms would be retrieved in an explosion search.)
(-) and (+) show where tree levels can be collapsed or expanded. For example, you can click on the broader term ischemia to see additional terms under that level. Or, click the (-) adjacent to heart infarction if you wish to suppress the display of its narrower terms.
The number next to the term shows the number of Embase records currently indexed to it. You can click the number to post them directly to the Session Results page.
Above the top of the tree display is a box offering several options for carrying the search forward:
Explosion
Include all narrower (more specific) terms in the search query, without having to enter each one individually. An excellent way to search for large groups of related concepts very quickly.
As major focus
Limits to records where the term(s) are the main emphasis of the article; eliminates references where they are merely peripheral or implied. This is an effective way to maximize search relevance and reduce your number of hits.
Take this term to X Search
Posts the term to the Disease Search page (for disease names), Drug Search page (for drug/chemical names) or Advanced Search (everything else), so that limits, date ranges subheadings or additional terms can be added.
Add to Search Form
Adds the selected term to the Emtree Search box at the top of the page. If other terms are already present there, the new one is added with a Boolean AND operator.
The bottom of the thesaurus page can also contain a term history note, a list of synonyms, a scope note (if applicable) and/or a definition from Dorlands Medical Dictionary.
