DEEP INDEXING

12

60K terms (>260,000 synonyms) and all MeSH terms

Over 30K drug and chemical terms

What is mapping?

Mapping means that searchers get the same results

regardless of which term they use, e.g. Vioxx (synonym) or rofecoxib (the

preferred term).

Updated 3 times a year (back-posting each time)

All drug generic names described by FDA and EMA, all International Non-Proprietary Names (INNs) described by WHO from 2000.

Deep indexing - Emtree

14 study types, including NEW Diagnostic Test Accuracy Study

78 drug and disease subheadings

PRECISE RETRIEVAL

Start searching…

Find the best terms for your search and include synonyms automatically with

autocomplete in Quick Search

Click on Disease Filter for example, to see which diseases are referenced with Januvia, either as a therapeutic area or side effect.

Find deep drug and disease relationships without having to consult the full text.

Building and combining searches

• Use single quotes to capture a phrase ‘diabetes mellitus’ for example (not with Autocomplete in Quick Search)

• Break up your search into individual searches, such as a drug search (in Drug Search form) and a disease search (in Disease Search form) and combine your results in Session Results

• Run your cursor over your search to Edit or copy to a Search Form for guided editing.

• Truncation and operators, AND, OR, NOT, NEXT, NEAR

Refer to http://info.embase.com/helpfiles for more guidance and links to materials such as the Quick User Guide.

Refining your search

• Quick and Advanced Limits on Advanced, Drug and Disease Search forms

• Major Focus on all advanced forms – major drugs and diseases retrieved

• Field limits under Advanced Search box to search in specific fields such as article title, abstract, conference name, drug name etc

• Drug and Disease Subheadings to limit to specific concepts such as Adverse Drug Reaction, Drug Comparison and Side Effect.

• Filters on Session Results page for specific diseases or study types for example
