If the box says “blog score 34” the first word shows what the
result is (a blog post, a site page, or an event). The rest is the
score, representing how relevant the result is to the keyword. The
higher the score, the more relevant.
So, for example, a search for “Nights of Lights” will search all
blog posts, pages and events for “Nights of Lights” “nights” and
“lights” And then count the number of times each word or phrase
appears in each search result. I then sort the search result list
by that score before displaying it.
