The Function type exposes the following members.

Methods

	Name	Description
	BitdotT	Returns the sum of products of each bit of a mask multiplied with its weight.
	Crc32	Calculates the CRC32 value for a string.
	ExistT	Returns the value of the attribute if it exists in the index(es), otherwise returns the provided default value.
	Fibonacci	Calculates the n-th Fibonacci number.
	Geodist(Single, Single, Single, Single)	Calculates the geosphere distance between the two points given by their coordinates. The coordinates must be provided in radians.
	Geodist(Single, Single, Single, Single, GeodistanceOptions)	Calculates the geosphere distance between the two points given by their coordinates.
	GroupByT	Returns the value by which a grouping was made.
	Idiv	Returns the result of an integer division of the first argument by the second argument.
	MinTopSortValue	Returns the sort key value of the worst found element in the current top-N matches if sort key is float and 0 otherwise.
	MinTopWeight	Returns the weight of the worst found element in the current top-N matches.
	PackedFactors	Can be used in queries to see all the weighting factors calculated when doing the matching. This function works only if expression ranker is specified and the query is not a full scan, otherwise it will return an error.
	Rand	Returns a random value.
	Sint(ExpressionFuncInt64)	Force Sphinx to reinterpret the given 32-bit unsigned integer argument as signed, and to also expand it to 64-bit type.
	Sint(Int64)	Force Sphinx to reinterpret the given 32-bit unsigned integer argument as signed, and to also expand it to 64-bit type.
	ZonespanList	Returns pairs of matched zone spans.

Remarks

These methods must not be used outside the fluent API, as they are only implemented as stubs.
