Advanced Search - Smart Engine

This app allows you to perform advanced web searches with just inputting keywords.
Web searches can be conducted using search operators, enabling various search options. However, using search operators often requires combining alphabets and symbols with spaces, which can become cumbersome.
For instance,
When you want to search for "Apple Inc." articles within Wikipedia's page content, you would need to input the following:
allintext: apple -fruit site:wikipedia.org
The app automatically generates such commands, enabling you to perform advanced searches by just inputting keywords. The search engine used is Google.
