-------------------------------------
Hi Lewis
bq. Can you confirm what you would like to see added to the wiki?, I will try
my best to get this added, are you referring to the [0]?
Nope. I meant replacing the wiki page written by Elizabeth with instructions on
what to do to get the metatags parsed and indexed. What I committed relies on
another plugin for indexing metadata whereas the old one had its own indexer
etc...
bq. Also I thought the best thing to do regarding porting to Nutchgora is just
to add it to the ever growing NUTCH-1104 list, so I have done so. If and when
this is required over there someone can duly oblige
good thinking
bq. Regarding adding fields to Solr I assume you mean schema and
solr-mapping.xml?
yes, this will be needed if we want this to be on by default which I think is a
good idea
bq. Finally can you expand on 'activate by default', what exactly is it that
not activated by default? I read your README.txt but I can see any mention of
it in there.
Plugins have to be listed in plugin.includes in order to be used. Thinking
about it it would be good to declare a dependency to index-metatags so that the
later is activated automatically (assuming plugin.auto-activation = true)
Thanks

> 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}
