Can I create a Search within one topic?

Question

Here is my challenge:
(1) Building WebHelp for a web-based data application in 8.0.2.208 (I also have one member working on 5.0.1)
(2) The web-based data application has 1530 data definitions
(3) The Product Manager would like the ability to perform a search for a data defintion by allowing the user to enter text and then initiating a search specific to the list of data definitions and not including the entire application help (i.e., a search on one topic or a collection of topics)
Not sure if this is possible. I would like to:
(1) Have one primary topic with the name of every data definition in the application (again 1530 of them)
(2) Have an entry field where the user types part of the data definition name and allow them to click a button to initiate the search
(3) Put the user at the first item that matches their search
(4) Each item would be a hyperlink to the actual data definition - OR - have all data definitions on one page (YIKES)
--- OR ---
(1) Have a collection of topics with data defintions
(2) Allow the user to enter search criteria and limit the results to the collection of topics related to the data definitions
Is there an "in topic search control" or a search control that can be limited to one topic or a collection of topics?
I have looked at setting up a form with a form field/text field and command button but I cannot find any substantive documentation on how this works or what I need to get it to work.
Any suggestions?  As always, thanks for any input.

Two last things:
(1) In the Skins setup, I had to add the "Search.html" in the skin to the "ZoomSearch" button using Links and not Advanced. Having it in Advanced did not open the Search form in my help. When I clicked the ZoomSearch menu bar item, it just flashed and did not open the ZoomSearch search topic.
(2) I got the search processing to work in my project, but at some point it stops working. The search topic displays when I click ZoomSearch and results are shown but when I click the link to go to the page listed in the results, I get the standard "Internet Explorer cannot display the web page".
When I look at the link it has:
file:///C:/Research/SearchProcessing/!SSL!/HPI_Change_Metrics.htm
It should have:
file:///C:/Research/SearchProcessing/!SSL!/WebHelp/HPI_Change_Metrics.htm
All I did was re-compile the WebHelp, re-publish the WebHelp, regenerate the search index and repost the 5 Search related files into my WebHelp folder (in the search_files folder). Any idea why it would not have the "WebHelp" included in the path?
