-------------------------------------
Summary: Dynamic boost lite
Key: OAK-9461
URL: https://issues.apache.org/jira/browse/OAK-9461
Project: Jackrabbit Oak
Issue Type: Task
Components: indexing
Reporter: Fabrizio Fortino
Assignee: Fabrizio Fortino
Dynamic boost uses index time boosting. This requires to have a separate field
for each unique term that needs to be boosted. With a high number of terms
(thousands), this could result in a sparse index that requires extra disk
space. Usually, dynamicBoost and similarityTags are configured on the same
field. In this case, similarityTags work on the same set of terms without the
need to store boost values. This does not affect the index size.
With *oak.search.dynamicBoostLite=lucene* no index time boosting is used for
lucene types indexes. The terms will affect the query match clause but the
scores won't be the same. In summary, in lite mode, the query will have the
same recall but lower precision.
