Hi,
> Can Nutch index custom HTTP headers?
Nutch stores the HTTP response headers if the property
`store.http.headers` is true. The headers are saved as
string concatenated by `\r\n` under the key
`_response.headers_` in the content metadata.
You can send the entire HTTP headers to the indexer using
the plugin index-metadata and adding `_response.headers_`
to `index.content.md`. It will add a field `_response.headers_`
to the index:
% bin/nutch indexchecker \
-Dplugin.includes='protocol-okhttp|parse-html|index-metadata' \
-Dstore.http.headers=true \
-Dindex.content.md=_response.headers_ \
'http://localhost/'
fetching: http://localhost/
...
_response.headers_ : HTTP/1.1 200 OK
Date: Mon, 11 Mar 2019 16:03:41 GMT
Server: Apache/2.4.29 (Ubuntu)
Last-Modified: ...
But there is no standard way to pick single headers and send
them to the indexer as arbitrary fields.
Best,
Sebastian
