  • All Implemented Interfaces:

    public class PatternReplaceCharFilter
    extends BaseCharFilter
    CharFilter that uses a regular expression for the target of replace string. The pattern match will be done in each "block" in char stream.

    ex1) source="aa  bb aa bb", pattern="(aa)\\s+(bb)" replacement="$1#$2"
    output="aa#bb aa#bb" NOTE: If you produce a phrase that has different length to source string and the field is used for highlighting for a term of the phrase, you will face a trouble.

    ex2) source="aa123bb", pattern="(aa)\\d+(bb)" replacement="$1 $2"
    output="aa bb"
    and you want to search bb and highlight it, you will get
    highlight snippet="aa1<em>23bb</em>"
