Gérald Quaire created LUCENE-8655:
-------------------------------------
Summary: No possibility to access to the underlying "valueSource"
of a FunctionScoreQuery
Key: LUCENE-8655
URL: https://issues.apache.org/jira/browse/LUCENE-8655
Project: Lucene - Core
Issue Type: Improvement
Affects Versions: 7.6
Reporter: Gérald Quaire
After LUCENE-8099, the "BoostedQuery" is deprecated by the use of the
"FunctionScoreQuery". With the BoostedQuery, it was possible to access at its
underlying "valueSource". But it is not the case with the class
"FunctionScoreQuery". It has got only a getter for the wrapped query,
For development of specific parsers, it would be necessary to access the
valueSource of a "FunctionScoreQuery". I suggest to add a new getter into the
class "FunctionScoreQuery" like below:
{code:java}
/**
* @return the wrapped Query
*/
public Query getWrappedQuery() {
return in;
}
/**
* @return the a source of scores
*/
public DoubleValuesSource getValueSource() {
return source;
}
{code}
