Examples of it.unimi.dsi.mg4j.query.nodes.MultiTerm

it.unimi.dsi.mg4j.query.nodes.MultiTerm
A node representing a virtual term obtained by merging the occurrences of the given (possibly weighted) terms.
This node is mainly useful when performing query expansion. The {@link QueryBuilderVisitor}used to generate {@linkplain DocumentIterator document iterators} can decide whichpolicy to use for setting the frequency and the name of the virtual term. @author Sebastiano Vigna @see MultiTermIndexIterator
