Class PatternReplaceCharFilter
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>"
