There is a help page. While you're there read through WebCrawler's Help and FAQ's. It's a good habit to read through the Help and FAQ before using any search engine. WebCrawler's database is significantly smaller than Lycos'. Many obscure pages will not turn up in WebCrawler.
Search results are very limited.
You get the title of the page and nothing else. You just need to try the links out. WebCrawler only includes Web pages. With WebCrawler you will not be able to find ftp, telnet or gopher sites. The database is updated every 6 weeks.
