Why are there no search results for my hashtags or locations queries?
If there are little or no results for the hashtags you perform search on, please try to type in more popular hashtags and repeat the search. Some popular hashtags, such as #woman, can bring no search results as well because the posts under such hashtags have been reported as content that may not meet Instagram’s community guidelines and were hidden on Instagram itself.
If you experience issues with location searches, try to use specific and popular locations. In this version, Combin search engine is searching for the photos in the location that person has mentioned in the post, so it doesn't mean that it covers the geographic area. In the next version we will introduce the map, so the search engine will search in the defined radius covering all location items like commercial objects or sights. Until the updated version is out, please perform search in specific, popular locations.
