Due to the fuzzy way language is used, one cannot simply compare 'go', 'clojure', or 'scala' search quantities directly. Not everybody refers to 'Go' as 'golang', 'scala' is a common noun in some languages, etc.<p>At best, you can reframe your query to remove unrelated topics completely, with searches like "golang" and "scala language", which will be <i>proportional</i> to the search popularity of the topics but only a fraction of actual searches (a different fraction for each searchterm, but stable over time), and compare their relative rates of growth rather than their absolute levels.
