Description

@catmorales I'm not sure to understand. When you type something in the search field the list of map templates is already filtered by matching what is in both title and description.

In addition the description field contains a simple full text where it is not possible to clearly identify/match specific words to provide to the user. What should be the criteria in your opinion?
