Haystack more_like_this 返回全部

我正在使用 Django、haystack、solr 进行搜索。我已经能够搜索，现在我想使用 more_like_this 查找类似的项目。当我尝试使用 more_like_this 功能时，我会返回该模型类型的所有对象，而不仅仅是与其密切匹配的对象。这里有一些代码向您展示我如何使用它：

def resource_view(request, slug):
    resource = Resource.objects.get(slug=slug)
    versions = Version.objects.get_for_object(resource)
    related = SearchQuerySet().more_like_this(resource)
    add_comment_form = AddCommentForm()
    return render_to_response('resources/resource.html',
                              {'resource': resource,
                               'versions': versions,
                               'related': related,
                               'add_comment_form': add_comment_form},
                              context_instance=RequestContext(request))

显然我需要在 solrconfig.xml 文件中启用 mlt。有人知道如何做到这一点，或者有帮助的文章/教程吗？

I am using Django, haystack, solr, to do searching. Ive am able to search and now I would like to find similar items using more_like_this. When I try to use the more_like_this functionality I get back all of the objects that are of that model type instead of just the ones that closely match it. Here is some code to show you how I am using it:

def resource_view(request, slug):
    resource = Resource.objects.get(slug=slug)
    versions = Version.objects.get_for_object(resource)
    related = SearchQuerySet().more_like_this(resource)
    add_comment_form = AddCommentForm()
    return render_to_response('resources/resource.html',
                              {'resource': resource,
                               'versions': versions,
                               'related': related,
                               'add_comment_form': add_comment_form},
                              context_instance=RequestContext(request))

Apparently I need to enable mlt in the solrconfig.xml file. Anyone know how to do this, or an article/tutorial that is helpful?

陈旧的问题，但无论如何，这就是答案：

正如 John 已经指出的那样，您需要将更多类似此处理程序（MLT）添加到您的 solr 配置中。这应该可以，将其放在 solrconfig.xml 中的某个位置，然后重新加载 SOLR (Tomcat)：

<requestHandler name="/mlt" class="solr.MoreLikeThisHandler">
<lst name="defaults">
  <str name="mlt.mintf">1</str>
  <str name="mlt.mindf">1</str>
  <str name="mlt.minwl">3</str>
  <str name="mlt.maxwl">15</str>
  <str name="mlt.maxqt">20</str>
  <str name="mlt.match.include">false</str>
</lst>
</requestHandler>

stale question, but here's the answer anyway:

As John already pointed out, you need to add the more like this handler (MLT) to your solr config. This should do, put it somewhere in your solrconfig.xml, and reload SOLR (Tomcat):

<requestHandler name="/mlt" class="solr.MoreLikeThisHandler">
<lst name="defaults">
  <str name="mlt.mintf">1</str>
  <str name="mlt.mindf">1</str>
  <str name="mlt.minwl">3</str>
  <str name="mlt.maxwl">15</str>
  <str name="mlt.maxqt">20</str>
  <str name="mlt.match.include">false</str>
</lst>
</requestHandler>
