Error when reproducing Gazetteer Example

[hlra]

I am trying to reproduce the Gazetteer Example. This line:
results = gazetteer.search(messy, n_matches=1)

Throws the following error:

Traceback (most recent call last):
  File "C:\ProgramData\Anaconda3\envs\dst\lib\code.py", line 90, in runcode

    pairs = con.execute(
sqlite3.OperationalError: no such table: indexed_records

I tried to look into the code to figure out what's going on but I'm afraid I do not understand. I am using dedupe 2.0.17.

did you call the index method before calling search?
