-      <string>Imagine searching for the word 'cats'. One dictionary lists
-it as a synonym for 'cat', another one only knows 'cat'
-alone. With this option on, the first dictionary would help
-discover the main word 'cat' which would be added to the
-query, and both dictionaries would include a definition for
-'cat' in response to the 'cats' query. This is very useful in
-most cases, and thus it is recommended to keep this on.</string>
