> h2. Parse-metatags plugin
> The parse-metatags plugin consists of a HTMLParserFilter which takes as parameter a list of metatag names with '*' as default value. The values are separated by ';'.
> In order to extract the values of the metatags description and keywords, you must specify in nutch-site.xml
> {code:xml}
> <property>
>   <name>metatags.names</name>
>   <value>description;keywords</value>
> </property>
> {code}
> The MetatagIndexer uses the output of the parsing above to create two fields 'keywords' and 'description'. Note that keywords is multivalued.
> The query-basic plugin is used to include these fields in the search e.g. in nutch-site.xml
> {code:xml}
> <property>
>   <name>query.basic.description.boost</name>
>   <value>2.0</value>
> </property>
> <property>
>   <name>query.basic.keywords.boost</name>
>   <value>2.0</value>
> </property>
> {code}
