@Andy298 as @Steve143 mentioned, the text box is only is used for location (it determines where the map is moved to). Any other text you put in there does not help find listings.
I looked in the area (without any search filters) and when the map is zoomed to your location, your listings rank
One Bedroom Apartment: #219/300+
Private Guest House: #250/300+
Both listings have the "New" tag on them, which provides a powerful and significant boost to your search rankings. It is worrisome that despite having the "New" tag both listings are ranked so low in the search results. Once the "New" tag is no longer applied, they will drop significantly (and they are already not appearing in the top 300 for many searches).
(Not being in the top 300 for a given area of the map is why you can't see your listing when you search.)
If you can, try to figure out why your listings are so low on the list. I saw some other "New"-tagged listings also very low in the search results (one even had a highly rated host). All of these low ranked "New" listings had Instant Book off.
I don't know if turning on Instant Book is possible for you, but it seems in your area it might be a big help.
