NDR provides the relevance level of matching documents based on the terms found. To boost a term use the caret, “^”, symbol with a boost factor (a number) at the end of the term you are searching. The higher the boost factor, the more relevant the term is in the search. Boosting allows you to control the relevance of a session by boosting its term. For example, if you are searching for download patch and you want the term download to be more relevant, boost it using the ^ symbol along with the boost factor next to the term. You would type: download^4 patch
This will make documents with the term download appear more relevant. You can also boost phrase terms as in the example: download patch”^4 “install tools
By default, the boost factor is 1. Although the boost factor must be positive, it can be less than 1 (e.g., 0.2).
