There isn't a tutorial or video for this. and depending on the complexity of the search you are trying to build, you may be better of sticking with data Bridge to create this, for example if you are trying to create a key word search, that is going to be difficult to accomplish as it will take custom coding.
for a fairly simple search:
Create a Search form on your search page. the search form should use the get method.
Then on the results page, create the recordset to filter the results.
in the where clause, create a condition for each search form element. for example if the search form searches the products table and has an element for ProductName create the recordset as:
SELECT * FROM products
WHERE (ProductName = paramProductName OR -1 = paramProductName1)
in the variables section, create 2 variables as:
Name: paramProductName
Type: Text
Default value: -1
Runtime value: $_GET['ProductName']
Name: paramProductName1
Type: Text
Default value: -1
Runtime value: $_GET['ProductName']
