使用 solr 索引维基百科转储 [英] Indexing wikipedia dump with solr

问题描述

我的机器上安装了solr 3.6.2，与tomcat完美运行.我想使用 solr 索引维基百科转储文件.如何使用 DataImportHandler 执行此操作?还有什么办法吗?我对 xml 一无所知.

I have solr 3.6.2 installed on my machine, perfectly running with tomcat. I want to index a wikipedia dump file using solr. How do I do this using DataImportHandler? Any other way? I don't have any knowledge of xml.

我提到的文件在提取时大约有 45GB.任何帮助将不胜感激.

The file I have mentioned has size of around 45GB when extracted. Any help would be greatly appreciated.

更新-我尝试做 DataImportHandler 页面上所说的.但是有一些错误可能是因为他们的 solr 版本要旧得多.

Update- I tried doing whats said on the DataImportHandler page. But there is some error maybe because their version of solr is much older.

我的 data.config-

My data.config-

<dataConfig>
    <dataSource type="FileDataSource" encoding="UTF-8" />
    <document>
    <entity name="page"
            processor="XPathEntityProcessor"
            stream="true"
            forEach="/mediawiki/page/"
            url="./data/enwiki.xml"
            transformer="RegexTransformer,DateFormatTransformer"
            >
        <field column="id"        xpath="/mediawiki/page/id" />
        <field column="title"     xpath="/mediawiki/page/title" />
        <field column="revision"  xpath="/mediawiki/page/revision/id" />
        <field column="user"      xpath="/mediawiki/page/revision/contributor/username" />
        <field column="userId"    xpath="/mediawiki/page/revision/contributor/id" />
        <field column="text"      xpath="/mediawiki/page/revision/text" />
        <field column="timestamp" xpath="/mediawiki/page/revision/timestamp" dateTimeFormat="yyyy-MM-dd'T'hh:mm:ss'Z'" />
        <field column="$skipDoc"  regex="^#REDIRECT .*" replaceWith="true" sourceColName="text"/>
   </entity>
    </document>

Schema(我只是将他们在网站上提供的部分添加到我的 schema.xml 文件中)

Schema (I just added the parts they have given on the website to my schema.xml file)

我得到的错误是 -

<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">0</int>
</lst>
<lst name="initArgs">
<lst name="defaults">

推荐答案

简单的帖子不是索引维基百科的正确方法.您需要研究改用DataImportHandler.DIH 支持流式导入.

Simple post is not the right way to index Wikipedia. You need to look into using DataImportHandler instead. DIH supports streaming import.
