In our experience, the following configuration is well suited in order to use a full-text search as a German address search.
Application Configuration- Common - Full-text search:
•Usage of "-" as a word delimiter

Settings in the Application Configuration via "Full-text search"
Application Configuration - Common - Limits:
•"Maximum list value count" should be set at 10000

Settings in the Application Configuration via "Limits"
Project / Edit / Full-text search:
•Usage of the search operator "AND"
• "Number of suggestions" should be set at 30

Settings in the Project via "Full-text search"
Hint: After the adaption of the configuration, the indices have to be calculated again and the application has to be reloaded!
