Searching library catalogs for a particular language may retrieve entries for films in which search term is not the primary language.  Why?

Many library searches default to a a keyword search.  As a result, the search retrieves any entries where a particular word appears, regardless of context.  For example, a search for "Italian" will retrieve films about Italian-American families, in addition to films in the Italian language.  Likewise, searching for a language will find catalog records where that language is one of the subtitle options.  While a Portuguese language learner might wish to watch "Ghostbusters" with Portuguese subtitles, one doesn't typically classify "Ghostbusters" as a film in Portuguese.
