M_OR

Name

M_OR

Synopsis

Returns records where any the terms or subqueries are present.

Arguments

M-value
List of terms and subqueries

Ranking Scheme

m * max( termweight ) + ( 1 - m ) * min( termweights )

Ranks using the mixed maximum and minumum method. This is effectively a variation of fuzzy logic that biases the result of the OR with an AND. A passed in m-value (the first argument) determines how much it is like an OR and how much like and AND. Typical values for M_OR are .2 to .5, although some experimentation may be necessary to find the best fit for your need.

Comments

M_OR returns any hit for the terms or subqueries.

Example

M_OR( 0.3, 'blue', 'green', 'red', 'orange', 'violet' );
