User-defined variables in Search Results pane

I am working with user-defined variables for WebHelp output. I have successfully added the variables to the topic, the displayed topic title, the TOC, and the Index entries. The problems lies in getting the search output to display the specified variable text.

For example, the base topic title is "Introduction to XX". I use a variable to change the XX to YY throughout the project; however, when I generate the output and then Search for YY, the search results pane displays "Introduction to XX" even though the displayed topic is titled, correctly, "Introduction to YY". I am assuming, because the topic title is not adhering to the variables, that the search results displays the metadata <title>.

What should I do so the search results title syncs with the other data?
