When searching for "fiets" (dutch for bicycle) in English Wikipedia, [[Bicycle]] is second in the list of results. But the displayed text is not always the same. Most times it shows the beginning of the article (which does not include that word or any similar words):

But sometimes it displays the language links which has the words "fiets":
55 KB (8,105 words) - 02:20, 26 August 2011
The sample text and the word count are different.
Searching for translations of bicycle in other languages ("cykel", "fietse", "sykkel") does not usually find [[Bicycle]]. Unless that word is also used in other places than the language links, like German "Fahrrad" in the name of an image. So it looks like language links should not not usually be included in the search.
