R_OR

Name

R_OR

Synopsis

Returns where any the terms or subqueries are present.

Arguments

List of terms and subqueries

Ranking Scheme

Ranks using the probabilistic method. The returned weight for hits in a record is the probability of all the terms that were found in that record being found together. That is calculated by multiplying the probability of those terms not occuring and taking the complement of this.

Comments

R_OR returns any hit of the terms or subqueries. R_OR is the same as the operator VALUE. We gave it the name VALUE as well since statistically it returns the value (probability) of the terms being found together. Because this is a frequently used operator, the name VALUE seemed more intuitive and easier to remember and read.

Example

R_OR( 'blue', 'green', 'red', 'orange', 'violet' );
