I have tried space, underscore and asterisk.
Is there any character(s) I could add into ABCD to disrupt the search function?
Hello @wayne.hewitt​,
My name is Henry and I am happy to assist with your inquiry, and appreciate you contacting LastPass Support!
Unfortunately, the search function can't be disrupted and will always show matches as long as you type a combination of characters that matches with an item.
Thank you,
