How to correctly search (Real Estate Transaction Standard aka RETS) server?

Question

I am trying to interact with a RETS (Real Estate Transaction Standard) server to find all listings where matrix_unique_id field is greater than or equal to 0.

After logging in, I tried the following URI

Search.ashx?SearchType=Property&Class=Listing&Limit=1000&Query=(matrix_unique_id=0+)&StandardNames=0

The above call returns

<RETS ReplyCode="20201" ReplyText="No Records Found."/>

But then I supplied a valid Matrix_Unique_Id value like this

Search.ashx?SearchType=Property&Class=Listing&Limit=1000&Query=(matrix_unique_id=59075770+)&StandardNames=0

Now that returns something but not what I am expecting. The returned value is as follow

Here is the documentation for RETS 1.7.2 and a PDF

Additionally, here is an example of how to search RETS server for a different server but both adhere to the same specification.

Additionally, I used RETS Connector to query the listing and I am able to download listings with no issues which indicated that my account is working and has permission to search.

Question: How can I correctly search up all properties where the field Matrix_Unique_Id is 0+?

Answer 1

For getting full result try the following logic,

(ModificationTimestamp=2000-01-01T00:00:00+)

This will return all the listings from the year 2000 onwards. If you need further old, give 1990 or older in the query.

Note: Your example query (matrix_unique_id=0+) is not working because of its pattern may not be correct, say 8 digit number only will take as input.
