Most database platforms will allow you to find variations of a word ending. This is called truncation. In most databases it is an asterisk.
Example:
hospital* will retrieve hospital, hospitals, hospitalization
Most databases will let you search a phrase by putting quotation marks around the phrase. Please note this does not always work, especially now that AI is used in several databases.
Example:
"evidence based medicine"
Some database platforms allow for a wildcard. This is used in a middle of a word. Depending on the database platform, you may need a # or $. Also depending on the database platform, this can be an optional character.
Example
wom$n
p#ediatrics (for British spelling)
