getDoubleValuesSource(String) - Method in class org.apache.lucene.expressions.SimpleBindings
getDoubleValuesSource(Bindings) - Method in class org.apache.lucene.expressions.Expression: Get a DoubleValuesSource which can compute the value of this expression in the context of the given bindings.
getRescorer(Bindings) - Method in class org.apache.lucene.expressions.Expression: Get a Rescorer, to rescore first-pass hits using this expression.
getSortField(Bindings, boolean) - Method in class org.apache.lucene.expressions.Expression: Get a sort field which can be used to rank documents by this expression.

haversinKilometers(double, double, double, double) - Static method in class org.apache.lucene.expressions.js.ExpressionMath: Returns the Haversine distance in kilometers between two points specified in decimal degrees (latitude/longitude).

INT_INDEX - Enum constant in enum class org.apache.lucene.expressions.js.VariableContext.Type: Brackets containing an integer index (ie an array).
integer - Variable in class org.apache.lucene.expressions.js.VariableContext: The integer value for this piece of the variable.
