I have tried with word “test” and it’s working perfectly for me.
Get search results from first shot: https://inspectorportal.millinfo.com/?s=test
When you are searching for something and there is no match in database you will get message similiar to this:
Your search for "adsasd" did not match any entries
and that’s normal Evolve behaviour, so basically try searching some text that you already added via posts or page like i gave an example with “test” keyword.
Please let me know if you have still problem with searching.
