By default, for a search to be indexed, the search string must be at least three characters long, without

minimum length of the search key is helpful to increase the number of indexed searches.

would not be. Indexed searches are significantly faster than unindexed searches, so changing the
minimum length of the search key is helpful to increase the number of indexed searches.
