[jira] [Updated] (NUTCH-1244) CrawlDBDumper to filter by regex

     [ https://issues.apache.org/jira/browse/NUTCH-1244?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Markus Jelsma updated NUTCH-1244:
---------------------------------

    Attachment: NUTCH-1244-1.5-1.patch

Patch for 1.5. It relies on an exact match of the whole expression using Matcher.matches(). However, i believe Matcher.find() would be more suitable as it allows substrings to be matches as-is without having to match the rest of the URL with a character class and a quantifier. This allows non-regex-experts to quickly get a list of URL's with a given substring as well.
