Format Guide

How to enter keywords:

Primary Keyword: Enter the main/preferred term for a concept
Synonyms: Enter alternative terms separated by semicolons ;
Leave rows blank if you don't need all 5 keyword groups
The tool will find ANY of these terms and return ALL related terms

Example:

Primary: Prisoner of War
Synonyms: POW; POWs; prisoner of war

Special Handling:

"US" is matched exactly to avoid confusion with the word "us"
Word boundaries are respected (prevents partial matches)
Results are alphabetised and deduplicated

How it works: When ANY variant is found in your text (primary OR synonym), the tool returns the complete standardized set of terms for that concept.
