Dear Wiki user, You have subscribed to a wiki page or wiki category on "Solr Wiki" for change notification.
The following page has been changed by NoblePaul: http://wiki.apache.org/solr/FunctionQuery The comment on the change is: marked the new feature in 'map' as a 1.4 feature ------------------------------------------------------------------------------ map(x,min,max,target) maps any values of the function x that fall within min and max inclusive to target. min,max,target are constants. It outputs the field's value if it does not fall between min and max. Example Syntax 1: '''map(x,0,0,1)''' change any values of 0 to 1... useful in handling default 0 values - Example Syntax 2: '''map(x,0,0,1,0)''' change any values of 0 to 1 . and if the value is not zero it can be set to the value of the 5th argument instead of defaulting to the field's value + Example Syntax 2 <!> ["Solr1.4"]: '''map(x,0,0,1,0)''' change any values of 0 to 1 . and if the value is not zero it can be set to the value of the 5th argument instead of defaulting to the field's value
