A methodology for planning and creating a multi-database search strategy consists of the following steps:
Determine a clear and focused question
Describe the articles that can answer the question
Decide which key concepts address the different elements of the question
Decide which elements should be used for the best results
Choose an appropriate database and interface to start with
Document the search process in a text document
Identify appropriate index terms in the thesaurus of the first database
Identify synonyms in the thesaurus
Add variations in search terms
Use database-appropriate syntax, with parentheses, Boolean operators, and field codes
Optimize the search
Evaluate the initial results
Check for errors
Translate to other databases
Test and reiterate
