Please, note the following Search app behavior. I upload the file, enter the text in the search field, and click “Search now”. In case of unsuccessful search, the system displays a “No search results” message, and removes the uploaded file. This is very inconvenient. It should be possible to repeatedly perform a search for the same uploaded file. Also, the downloaded search results file for some reason has the same name as the original uploaded file with text. That is confusing, especially when the file formats are also the same. The output file name should have some indication that this file contains the search results.
Thanks for your suggestion about the repeated search. We have logged it in our issue tracking system with the id AAPPS-60. We will keep you updated about this issue.
The issue with the same filename of the search results will be fixed in the near future.
