Term Weight Sets provide a way to change weights in the core ATG Search dictionary, and should not be used for adding new terms. For custom dictionaries, you can set the weight directly on the term or synonym.
Only one weight set can be specified per Search Project per language. Changing Term Weight Set values requires a complete re-processing of the content in a clean index in order for the changes to have predictable results.
Note: Term weight changes are very rarely required. Do not use this feature if you do not understand its potential impact on end-user searches.
