> As discussed [on the mailing list|https://www.mail-archive.com/user@.../msg16516.html], index-metadata fails to ignore a webpage with a capitalized robots metatag such as {{<META NAME="ROBOTS" CONTENT="NOINDEX, FOLLOW">}}. This only applies when parse-tika is used. parse-html will "decapitalize"
> Parsing the attached [^noindex.html] leads to the following results:
> *parse-html:*
> {code:java}
> bin/nutch parsechecker -Dplugin.includes="protocol-httpclient|parse-(html|metatags)|index-metadata" -Dindexer.delete.robots.noindex="true" -Dmetatags.names="robots" -Dindex.parse.md="metatag.robots" http://localhost:8080/noindex.html
> Parse Metadata: [...] metatag.robots=noindex,nofollow robots=noindex,nofollow{code}
> *parse-tika:*
> {code:java}
> bin/nutch parsechecker -Dplugin.includes="protocol-httpclient|parse-(tika|metatags)|index-metadata" -Dindexer.delete.robots.noindex="true" -Dmetatags.names="robots" -Dindex.parse.md="metatag.robots" http://localhost:8080/noindex.html
> Parse Metadata: metatag.robots=NOINDEX,NOFOLLOW  [...] ROBOTS=NOINDEX,NOFOLLOW [...]{code}
>  
> The field being named "ROBOTS" and not "robots" leads to {{parseData.getMeta("robots")}} being {{null}} in [https://github.com/apache/nutch/blob/master/src/java/org/apache/nutch/indexer/IndexerMapReduce.java#L257].
