I face strange behaviour with search result as I'm searching for a word inside an article in a subsite for a site collection.
This subsite has a default page with custom .net webpart to disply summary for all articles.
I changed the welcome page for the site collection to the default page of the subsite so when you write the site collection url it will redirect to default page of subsite. The probelm is search result come with 2 result of my word. The first one is the site collection url like this
"http://web/sitecollection" second one is the url of sub site
"http://web/sitecollection/subsite" and no result for the specific article that contains the search keyword.
I'm going to go crazy with SharePoint search engine if I need to add a crawling rule to remove those specific urls it will remove any page under this url.
