私はsolr-4.4.0とnutch-1.7を使用しています。私はsolrとnutchの初心者です。次のブログを使用してsolrとnutchを統合しようとしています::
http://www.building-blocks.com/thinking/building-a-search-engine-with-nutch-and-solr-in-10-minutes/
solr が正常に開始されました::
manish@ubuntu:~$ cd /usr/local/solr/example/
manish@ubuntu:/usr/local/solr/example$ java -jar start.jar
正常にインデックス化された URL と同様に::
manish@ubuntu:/usr/local/nutch/bin/nutch crawl urls -dir crawl -depth 3 -topN 50
出力例::
fetching http://www.tatvic.com/tatvic-excel-plugin-webinar (queue crawl delay=5000ms)
-activeThreads=10, spinWaiting=9, fetchQueues.totalSize=36
-activeThreads=10, spinWaiting=10, fetchQueues.totalSize=36
-activeThreads=10, spinWaiting=10, fetchQueues.totalSize=36
-activeThreads=10, spinWaiting=10, fetchQueues.totalSize=36
-activeThreads=10, spinWaiting=10, fetchQueues.totalSize=36
-activeThreads=10, spinWaiting=10, fetchQueues.totalSize=36

しかし、solrに投稿しているときに、次のようになりました::
manish@ubuntu:/usr/local/nutch$ bin/nutch solrindex http://127.0.0.1:8983/solr/ crawl/crawldb -linkdb crawl/linkdb crawl/segments/*
Indexer: starting at 2013-09-09 07:05:05
Indexer: deleting gone documents: false
Indexer: URL filtering: false
Indexer: URL normalizing: false
No IndexWriters activated - check your configuration
Indexer: finished at 2013-09-09 07:05:12, elapsed: 00:00:07
本当の意味は？
ブラウザでは何も表示されません::
http://127.0.0.1:8983/solr/select?q=tatvic
ブラウザのサンプル::
<response><lst name="responseHeader"><int name="status">0</int><int name="QTime">111</int><lst name="params"><str name="q">tatvic</str></lst></lst><result name="response" numFound="0" start="0"/></response>
何度も挑戦しました！！
問題になる可能性があると思います。
これを理解するのを手伝ってもらえますか??
