Purpose of setting a field to both String and Text

[havardox]

While browsing the examples repo, I came across this line of code:

https://github.com/dedupeio/dedupe-examples/blob/master/record_linkage_example/record_linkage_example.py#L110-L111

I'm curious as to why the title field is set to both String and Text. How does it improve linking accuracy compared to using either String or Text alone?

it simply allows for multiple methods to match on, rather than a single one
