Please explain Space Engineers Advanced Server Search

I try to use the Advanced Server Search in Space Engineers. But somehow I never get the results I want. Maybe I just don't get the meaning of the icons. There are three different status of these checkboxes:

• Filled with square
• Filled with dash
• Empty

I guess the first one (filled with square) says "I want that feature". But I'm not sure about the others. Please enlighten me.

Solution 1:

From my research, it seems the following is true

• Dash sign: the feature can be on or off

• Empty box: the feature is off for the server

• Filled box: the feature is on for the server

This is something not well documented and had to test for my research. My testing process was:

1. Access Advanced tab of the Advanced Server Search
2. Set one box to blank, filled, or dash then click Search
3. Select a server then click Server Details
4. Look for the world setting changed on step 2 and document if it's on or off
5. Repeat steps 1-4 until all box options have been tested
