The System Default Term Weights set is non-modifiable. However, you can add and delete individual terms and adjust weights within weight sets that you create.
To add a term to your weight set:
In the Administration Options menu, go to Search Workbench > Customizations > Term Weights > Your Weight Set.
Enter a term. When you begin typing the term, a new line appears below it, on which you can enter more terms.
Assign the weight. The range is 0 to 100, with 100 having the highest weight or influence in the search. The colored icon and Weighting Effect column changes to reflect the effect of the assigned weight.
Click Save.
