This plugin redirect search queries to Google, which used by V2MM, you can see what happened when you search on V2MM.
This plugin was modified from BenLubar's nodebb-plugin-google-search, only fixed one problem: BenLubar's original plugin blocked the hook "filter:search.query" with a dummy function, which leads the suggested topics widget not work, because that widget would call this api when it's on the topic's template.
