Wordpress Code Modification

I need someone who is familiar with the inner workings of the wordpress code. I need 2 things done. The first is to split the title of a word press post title based on a "|" symbol so that only part of the title appears in for example the Recent Post Widget (and the Post by Same Categories Widget). For example, I use post titles that contain the pipe symbol "|" to separate the posts title components. An example title might be 'My New Post One | Sold Products'. Currently when I use this as a title, I only want the 'My New Post One' to show in the Recent Post Widget (and the Post by Same Categories Widget). At the momement, the whole title such as 'My New Post One | Sold Products' shows in the Recent Post Widget (and the Post by Same Categories Widget). Somehow I need the title to be broken into 2 pieces based on the "|" symbol so we end up with 'My New Post One' and 'Sold Products' with just 'My New Post One' being shown in the Recent Post Widget (Post by Same Categories Widget). Attached are 2 images which shows a Before and After of what needs to be achieved. The second part of this project is to set up a second search page/routine in wordpress. At the moment for example, the following link [login to view URL] will perform a search of my site and put the results into the default [login to view URL] theme page. What I want is a way so that I can run another search string such as say: [login to view URL] (note the /?s2) that will perform a search of my site and put the results into a second [login to view URL] theme page which we might call for example search2.php. The second search page routine would be accessed with hard coded links so there would be no search form. i.e I would use a hardcoded link such as [login to view URL] shoes to initiate the second search routine that would put the results into the new [login to view URL] page. If this can be done some other way, I'd be happy to go with that. The main thing is being able to have access to a second search routine that allows us to drop results into a different search results page. Also if you place a bid make sure you include a mention of 'S2' in your bid response so that I know you have read ALL these details. I do understand that any code changes will probably be overwritten whenever I upgrade wordpress so I would also need to know which files have been modified so that when an upgrade of wordpress needs to take place I know where to make the appropriate changes.
