Query is not understandable

What happened

You tried to use a search formula, but your formula contains characters HCL Notes® doesn't accept in search formulas. In addition to letters and numbers, Notes® accepts only these characters: colon (:), backslash (\), period (.), and ampersand (&).

You may also see this message because:

• You're searching fields in a form, and the application designer included characters other than those listed above in a field. For example, the designer may have included Yes! as the text for a radio button in a dialog box, but Notes® doesn't accept the exclamation point.
• Your search formula syntax may be incorrect.

What you can do

Remove any characters in the search formula other than those listed above.
