The code example needs the parameter 'algorithm=brute' for the the custom distance metric with data indexing to work correctly. Otherwise, for larger datasets the default 'algorithm=auto' will choose an incompatible algorithm which breaks the custom data indexing. notebook with code demonstrating the issue: https://github.com/sillystring13/cuddly-barnacle/blob/master/Example%20-%20Sklearn%20FAQ%20code%20test.ipynb

Reference Issue
Related to: scikit-learn#7669
What does this implement/fix? Explain your changes.
Problem:
The doc/faq example "How do I deal with string data (or trees, graphs...)?" has a chunk of code that doesn't work if you increase the number of samples.
Fix:
The code example needs the parameter 'algorithm=brute' for the the custom distance metric with data indexing to work correctly. Otherwise, for larger datasets the default 'algorithm=auto' will choose an incompatible algorithm which breaks the custom data indexing.
Any other comments?
