Boost DocumentsQuery pipeline stage configuration specifications
The Boost Documents query pipeline stage adds boosting parameters to matched documents based on user-defined rules. Boosts are defined with a term value to boost and the boost factor to add. The boosting parameters are added to the bq
Solr query parameter.
The Boost Documents rule consists of the following elements:
-
field
. The document field to filter on. -
keywords
. The words, phrases, or regex used as the filter. -
mode
. Filtering logic applied to keywords, one of:-
exact

Boost calculation
Numbers entered into boosts are multiplied with the score.
As a result of multiplication:
-
Negative boosts are not possible. You must use fractional values to deprioritize the score. For example, a boost value of 0.5 decreases the score by half.
-
Do not use values such as 100. If those values are entered, document scores are boosted to an unrealistically high level.
-
Managed Fusion generates an error when a query is executed on a pipeline that uses negative boost values.
