for example,  in fınd mode, when I write "...", " * "  like these operators in table. all records are coming. I want to cancel these operators for security. ıf it is possible or not.

You mean when the users do it you want nothing to happen?  You can trap for them with the OnObjectKeystroke event, or do a check with OnValidate if you do not want to do it at every keystroke...

I couldn't solve this problem.because  When I write "..." or " * " in fınd mode all records are coming.I want to use this in web publishing.

If you're doing this through Custom Web Publishing, then you can trap for these characters in the php script and exclude them...

 

Although I don't see why you would put this restriction - you want people to search for information, so why restrict the search?

"Escape" each character by preceding it with a backslash.  e.g.  enter * or .

I believe you are attacking this from the wrong end: if there are records your users are not supposed to see, deny access to them in their privilege set. Such records will be automatically omitted in any find your users perform.
