Use the following charts to compare field codes, truncation symbols, wildcards and proximity operators across a selection of health databases.
Search strategy translator tool (Polyglot)
Please note that the Polyglot tool is not perfect and does not remove the need to understand how the databases work. You will still need to check the results for accuracy and make some manual adjustments. For instance the Polyglot does not automatically map subject terms across databases (e.g. MeSH terms to Emtree terms). It is recommended that people have a basic understanding of how each database works, before using the Polyglot.
