Search customization question for rtfm

As you know, the search field and button in the upper-right of rtfm
has the default behavior and sense of searching the ‘summary’ of the rtfm
articles. I’m wondering if I can change that default behavior/sense
to search the ‘keywords’ of an article instead of the ‘summary’. Anyone
know how to accomplish that?

Happy Landings,
