Creating a basic search strategy
DEMO
Medische Bibliotheek Erasmus MC
Considerations
Explode a broad term or not?
Start exploded, be more specific if many irrelevant results appear
Truncate a term or not?
Truncate as much as possible, hardly noise (though not too short)
Phrases or proximity?
When available, use proximity, easier and more sensitive
How broad should proximity be?
Start with 3, increase in steps of 3 and evaluate new articles
Medische Bibliotheek Erasmus MC
Creating a basic search strategy (summary)
Type code in Word Open an element with () For emtree terms type ''/exp and paste term After pasting all emtree terms, type OR ():ab,ti within that element once
for free text words Type single word synonyms first Type (() NEAR/3 ()) somewhere in the document to reuse Copy (() NEAR/3 ()) into the ():ab,ti part search for phrase variants, and
add the words

Optimizing your strategy
Temporarily change the syntax and check words:
Per element, keeping the rest unchanged (emtree) NOT (free text) (free text) NOT (emtree)

Increase Sensitivity (always)
Add extra words Generalize specific elements Drop unimportant elements Split 1 element 2 elements
(mesh/subheading[mh]) (mesh[mh]) AND (subheading[sh])(phrases separate words)
2 elements 1 element (I) AND (C) (I OR C)
Temporarily broaden or drop a very specific element to optimize the others

Increase Specificity (if necessary)
Add an extra element 2 elements 1 element
([mh]) AND ([sh]) (mh/sh[mh])(combine words into phrases)
1 element 2 elements(I OR C) (I) AND (C)
Add Filters for date? or language?
If you can afford missing relevant refs: For the most important element: use [mj]
