      <handler class="com.norconex.importer.handler.filter.impl.RegexMetadataFilter"
          onMatch="[include|exclude]"
          caseSensitive="[false|true]"
          field="(name of metadata name to match)" >

      <restrictTo caseSensitive="[false|true]"
              field="(name of header/metadata field name to match)">
          (regular expression of value to match)
      </restrictTo>
      <!-- multiple "restrictTo" tags allowed (only one needs to match) -->

      <regex>(regular expression of value to match)</regex>
  </handler>

    Usage example:

    This example will accept only documents containing word "potato" in the title. 

      <handler class="RegexMetadataFilter"
          onMatch="include" field="title" >
      <regex>.*potato.*</regex>
  </handler>
