APA Style (7th ed.)
Cite quotations or paraphrases from the resource you located via the search (e.g., journal article, ebook), not the search itself. In general, "mentions of whole websites, whole periodicals, and common software and apps in the text do not require in-text citations or reference list entries because the use is broad and the source is familiar" (American Psychological Association, n.d., para. 3). If you're reporting on how many items came up in the search, describe your method in the sentence e.g., a Google Scholar search of X resulted in 13,000 results.
