Subject [jira] Updated: (NUTCH-442) Integrate Solr/Nutch
Date Mon, 19 Nov 2007 21:12:43 GMT


Doğacan Güney updated NUTCH-442:

    Attachment: NUTCH-442_v4.patch

Here is the latest patch. I can tell you that it compiles but I don't know if it runs or not

I don't have time to describe all the new things in the patch, but here is what my git-log
command tells me:

- Ported to latest trunk
- Revert unnecessary changes to languageidentifier.
- Java 5 compatibility fixes.
    * Don't use Override tags for "implement"ed methods.
    * Work around ExecutorService.invokeAll bug.
- Ugly hack for stringifying boolean queries.
    Adds a static stringify(BooleanQuery) method to SolrSearchBean. We can't just call
    BooleanQuery.toString() because it can produce strings like url:
    which is _not_ a valid solr query string. Method stringify produces them like

- Update segment names periodically in FetchedSegments.
    Added a new monitoring thread to FetchedSegments that watch
    for changes in the given segments directory and updates map
    'segments' accordingly. Map 'segments' is changed to a ConcurrentMap
    for thread-safety.

- SolrResponseHandler updates.
    * Don't buffer characters in SolrResponseHandler unless necessary.
    * Use StringBuilder.setLength(0) instead of creating a new StringBuilder.

> Hi:
> After trying out Sami's patch regarding Solr/Nutch. Can be found here (
and I can confirm it worked :-) And that lead me to request the following :
> I would be very very great full if this could be included in nutch 0.9 as I am trying
to eliminate my python based crawler which post documents to solr. As I am in the corporate
enviornment I can't install trunk version in the production enviornment thus I am asking this
to be included in 0.9 release. I hope my wish would be granted.
> I look forward to get some feedback.
> Thank you.
