Warning: This is a facade provided for use by user code, not for implementation by user code. User implementations of this interface are highly likely to be incompatible with future releases of the product at both binary and source levels.
org.apache.lucene.queries.function.ValueSource
Instantiates {@link FunctionValues} for a particular reader.
Often used when creating a {@link FunctionQuery}.
org.apache.lucene.search.function.ValueSource
Expert: source of values for basic function queries.
At its default/simplest form, values - one per doc - are used as the score of that doc.
Values are instantiated as {@link org.apache.lucene.search.function.DocValues DocValues} for a particular reader.
ValueSource implementations differ in RAM requirements: it would always be a factor of the number of documents, but for each document the number of bytes can be 1, 2, 4, or 8.
WARNING: The status of the search.function package is experimental. The APIs introduced here might change in the future and will not be supported anymore in such a case.
org.apache.solr.search.function.ValueSource
Instantiates {@link org.apache.solr.search.function.DocValues} for a particular reader.
Often used when creating a {@link FunctionQuery}. @version $Id: ValueSource.java 1140724 2011-06-28 17:00:20Z yonik $
org.codehaus.plexus.interpolation.ValueSource
Supplies one strategy for resolving a value for an interpolation expression. ValueSources may be stacked.
