Show Error Messages determines the disposition of error messages during searches. It may be set to one of the following values:
NoneSuppress all errors
In HTML commentsShow errors in HTML comments (for HTML results styles) so that they are not normally visible to the user, but can be viewed via View Source in a browser. In XML results styles, errors will be suppressed.
In HTML comments & query errors visibleShow errors in HTML comments (for HTML results styles), but show query-related errors (e.g. "Your query was all noise words.") visibly (in gray boxes).
The default is In HTML comments & query errors visible. Note that in admin (test search) mode, all errors are always shown visibly, for admin perusal.
