In order to get the most accurate and relevant results from Saasuma you can use the source selection feature. You can find this functionality in the Files section
In the 'Select Directory' section on LHS, chose the sources and accounts from which you would like to see results and enter the keyword you would like to search for.
Click on the dropdown button and select the sources from which you would like to have results in your search.
If you uncheck some of the sources already connected, you won't see images, files or videos that were synced from that particular source.
When you have set this up to your preference, just click the 'Enter' button on your keyboard and your results will be listed.
Hope this helps!
