If DefaultSearchProviderEnabled is on, then setting DefaultSearchProviderAlternateURLs specifies a list of alternate URLs for extracting search terms from the search engine. The URLs should include the string '{searchTerms}'. Leaving DefaultSearchProviderAlternateURLs unset means no alternate URLs are used to extract search terms. Example value: https://search.my.company/suggest#q={searchTerms} https://search.my.company/suggest/search#q={searchTerms}
