org.apache.lucene.analysis.pattern.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>"
