I’m comparing a few products that are common in one country but barely discussed in English-language reviews. Perplexity seems convenient for gathering sources, but I’m unsure whether its search results give enough weight to local retailers, publications, and regional product names.

For regional supplier research, have you found that changing the query language or naming local sites makes a noticeable difference? I’d especially like to hear how people check whether the sources actually reflect the market they’re researching rather than just repeating broad international coverage.
