Setting synonyms for full-text searches

Define synonyms to avoid specifying all of the possible alternative names for a term in a full-text search expression. Set the same set of synonyms for each index if you want the effect of synonyms on full-text search results to be consistent.

Synonyms
Synonyms do not apply to search expressions that have Boolean operators such as AND, OR, or NOT. Also, synonyms only apply to some types of search terms.
Removing all synonyms for an index
Remove all synonyms for an index if you no longer want to use synonyms for full-text searches.
Updating synonyms for an index
Configure synonyms for a new index or reconfigure synonyms for all indexes as needed.
Synonym input file: Format reference
The command-line synonym tool reads your specified synonym input file to set the synonyms for an index.
