Steps to reproduce the issue

This is more a doubt on a string than a real issue.
That's why I'd request the opinion of an English native speaker like @brianteeman or @Joomv

When you go on Component > Smart Search the first time, it asks you to create the index and it's right.
The button in the toolbar is "Index":

I know that "Index" is a verb, but it could be read also as a noun for the index itself.
Do you think that it could be better to change the button text into something like "Start Index" or "Build the index" or anything else that could help understanding that it's the right button to start the indexing process.
