How do I create these filters with Advanced Search Addon? Please help!

Hi,

Example one:
I’m creating a real-estate directory. How can I create an advanced search filter to only show businesses over $2million or between $500k and $750k (price filter).

Example two:
How can I create an advanced search filter to only show apartment units or only show houses.

As an additional question which is also linked to the above, how do I use the All-Imports Add-on to import a list of say, 20,000 properties with the filters discussed above (prices, property type, size, etc..)

Help would be highly appreciated!

Kindest regards.
