Right now you cannot omit this feature as it is baked in TikaParser. If no outlinks are detected the parser will use OutlinkExtractor to find plain text URL's and collect those as outlink.
You can open an issue for support of an option to toggle the outlink extractor. > hi all, > when i crawl pdfs ,nutch fetch any link in pdfs , > how can i omit this? > thanks a lot. > > -- > View this message in context: > http://lucene.472066.n3.nabble.com/how-can-i-crawl-pdfs-tp3364548p3364548. > html Sent from the Nutch - User mailing list archive at Nabble.com.
