Definition
The SCOREBIAS tag can appear zero or more times as a child of the R tag (see “R” on page 76) for each
result. The SCOREBIAS tag appears for each result biaser that is applied.
The NAME attribute is the name of the result biaser.
The VALUE attribute indicates the effect of the biaser. For biasers where the strength is expressed
symbolically, such as source or collection biasing and metadata biasing.
The search appliance does not include any information about the exact change in score or rank, or the
weight of the result biaser.
The following example indicates a medium increase in the PatternScorer result biaser:
