Doğacan Güney commented on NUTCH-445:
-------------------------------------
Has anyone looked at this? Google seems to do "site:" searches like this too. A
"site:apache.org" search doesn't only return results under apache.org but also
returns results under all sub-hosts (or whatever they are called) of
apache.org.
Also, IMO, this shouldn't be a seperate domain field in the index but rather,
should replace the site field. So (again IMO) this should not be a seperate
plugin but should be a patch to index-basic and query-site.
(PS: Enis and I know each other so you may want to take this with a grain of
salt.)

> Key: NUTCH-445
> URL: https://issues.apache.org/jira/browse/NUTCH-445
> Project: Nutch
> Issue Type: New Feature
> Components: indexer, searcher
> Affects Versions: 0.9.0
> Reporter: Enis Soztutar
> Attachments: index_query_domain_v1.0.patch,
> index_query_domain_v1.1.patch, TranslatingRawFieldQueryFilter_v1.0.patch

> Hostname's contain information about the domain of th host, and all of the
> subdomains. Indexing and Searching the domains are important for intuitive
> behavior.
> From DomainIndexingFilter javadoc :
> Adds the domain(hostname) and all super domains to the index.
> * <br> For http://lucene.apache.org/nutch/ the
> * following will be added to the index : <br>
> * <ul>
> * <li>lucene.apache.org </li>
> * <li>apache</li>
> * <li>org </li>
> * </ul>
> * All hostnames are domain names, but not all the domain names are
> * hostnames. In the above example hostname lucene is a
> * subdomain of apache.org, which is itself a subdomain of
> * org <br>
> *
>
> Currently Basic indexing filter indexes the hostname in the site field, and
> query-site plugin
> allows to search in the site field. However site:apache.org will not return
> http://lucene.apache.org
> By indexing the domain, we can be able to search domains. Unlike
> the site field (indexed by BasicIndexingFilter) search, searching the
> domain field allows us to retrieve lucene.apache.org to the query
> apache.org.
