Small correction to help page: Search prefix "label:"

I use colour labels to indicate work status on some files in the database and, for that purpose, changed the names of the colour labels in the preferences (think yellow is called “project head”, blue is “integrate in wiki” and so on).

The help page on search prefixes does list the label: prefix but describes only the ability to search for the colour label’s index number:

label: The color label of a file, from 0 (no label) though 7.

I discovered that it is also possible to search for the customized text labels using quotes in the syntax, e.g. `label: “Project Head”.

It would be great if you could update the help text to reflect that.
