Function Documentation

add()

void add ( void * set_handle, int seqno, TERMID term )

static

add: Called for each word occurence in a result set. This routine should be as fast as possible. This routine should "incrementally" update the score.

begin()

void * begin ( struct zebra_register * reg, void * class_handle, RSET rset, NMEM nmem, TERMID * terms, int numterms )

static

begin: Prepares beginning of "real" ranking. Called once for each result set. The returned handle is a "set handle" and will be used in each of the handlers below.
