in line 540 of java.net.nutch.tools.FetchListTool.java,
it comments that:
"//Modify the Page in the webdb so that its date is set forward a week. This way, we can have generate two consecutive different fetchlists without an intervening update"
My first Question is, what is "two consecutive different fetchlists" referring to exactly? Is it referring to the data structures in db/webdb/... and segments/200405xxxxxx/fetchlist/data?
And, my second question is how exactly is the time stamp plays a role in achieving that non-intervening operations.
Thank you,
