On Ubuntu12.10 64bit with openjdk7u9 and OSS1.4beta3.
1.Index -> Template Webcrawl -> Crawler -> Pattern List:
Give it a crawl(run once)
Query -> Select Search(left mouse click) -> Use "New Copied Query" with name "search_panel2" -> Edit "search_panel2" -> Filters -> look at document(inline help):
and add it
-> press search and see nothing.
4.The last is the problem.
As you can see I have just created a filter for one of the Url from pattern list.
Regarding to your documentation(cited above) this should give back after search excatly the result of the pattern.
It does not do this.
