[jira] Commented: (LUCENE-2728) EnwikiContentSource does not properly identify the name/id of the Wikipedia article

    [ https://issues.apache.org/jira/browse/LUCENE-2728?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12925848#action_12925848 ] 

Grant Ingersoll commented on LUCENE-2728:
-----------------------------------------

Also, the doc id is also guaranteed to be the second item.  So, upon seeing the first id for a page, we can ignore all other ids.

> The EnwikiContentSource does not properly identify the id (name in benchmark parlance) of the documents.  It currently produces assigns the id on the last <id> tag it sees in the document, as opposed to the id of the document.  Most documents have multiple <id> tags in them.  This prevents the ContentSource from being used effectively in producing documents for updating.
> Example doc:
> {quote}
> <page>
>     <title>AlgeriA</title>
>     <id>5</id>
>     <revision>
>       <id>133452200</id>
>       <timestamp>2007-05-25T17:11:48Z</timestamp>
>       <contributor>
>         <username>Gurch</username>
>         <id>241822</id>
>       </contributor>
>       <minor />
>       <comment>[[WP:AES|รข<86><90>]]Redirected page to [[Algeria]]</comment>
>       <text xml:space="preserve">#REDIRECT [[Algeria]] {{R from CamelCase}}</text>
>     </revision>
>   </page>
> {quote}
> In this case, the getName() return 241822 instead of 5.  page/id is unique according to the schema at  http://www.mediawiki.org/xml/export-0.3.xsd, so we should just get that one.
