This tool is easy to use, it's free for personal accounts too! It has an amazing feature of suggesting you what documents that are similar with your search query as results in SERP (Search Engine Result Page). You can also share them via email or social media channels like Twitter & Facebook by hitting "Share" icon at top right corner which helps me alot while solving my research papers problems! There was no major issues I faced using this software so far but sometimes some terms do not get suggested from Google autocomplete bar when typing into field box which could be annoying after sometime if used continuously often!! But these minor annoyances does Not really affect much because its one stop solution where we can find all our required information under single roof without searching through different sources online again n Again!! Definitely worth trying even once just out curiosity :D Great Product. Highly Recommended Software Tool For All Sear The best thing about Sphinx is that it allows you to search across multiple databases simultaneously. It's also very easy to use and can be set up in a matter of minutes. I dislike that it takes a little while for Sphinx to index new data, but this isn't really a problem. If you're looking for a way to quickly build out an enterprise search platform, Sphinx is a great option. We've been able to find records across our different databases with ease.
