This document provides tips for using Embase and systematic searching. It summarizes that Embase indexes over 8,000 journals and has over 60,000 controlled terms. Proximity operators like NEAR and NEXT can help narrow free text searches. Study types, populations, and evidence-based medicine filters are useful tools for leveraging search strategies. More information is available through Elsevier resources.

7. Use the study types filter and population option
- Study types and population are so called
checked tags; the indexers ‘must’ check for this
type of information.
- Detailed information on checktags and
description of it’s meaning can be found in
indexing guide 2012 (embase.com/info)

9. Using proximity operators
Proximity operators let you search for words or phrases at any specified distance
from each other.
NEAR/n
This requests terms which are within 'n' words of each other, in either direction.
cardiac near/5 catheter retrieves:
"Despite complicated cardiac anatomy, catheter ablation of AT..."?
"... patients undergoing catheter ablation for cardiac arrhythmias ..."?
"...a continuous thermodilution cardiac output pulmonary artery catheter."?
NEXT/n
This requests terms which are within 'n' words of each other in the order
specified.
hip next/3 prosthesis retrieves:
"... rheumatoid arthritis, joint surgery, hip or knee prosthesis ..."?
"metal on metal hip resurfacing, prosthesis failure (complication, diagnosis)..."?

Editor's Notes
Our more international coverage is true; yes we have more European, Asian and Latin American content, but not at a cost of our North American coverage; Roughly 2700 N-American journals in Embase; 2500 in Medline.
