----------------------------
Summary: page wise probabilistic elevation of result documents
based on combination of signal values
Key: SOLR-9806
URL: https://issues.apache.org/jira/browse/SOLR-9806
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Reporter: sachin
We had a requirement to elevate result documents based on individual signal
values and after searching thoroughly into available Solr modules, we couldn't
find anything and therefore decided to write our own module.
Problem Description: We wanted to boost results in a probabilistic fashion. i.e
x% of the results on each page must have a signal value above threshold value.
One immediate usecase that can be thought of is recent results. We want to
boost results which are above a certain threshold such that x% of the results
in each page belong to these recent documents.
Solution: We extend the solrQueryElevationComponent to support our
probabilistic elevation component. An additional comparator is added and the
overall runTime changes from nlogn to 2nlogn
