Search Improvement Question

I have tried this workaround using Find to search for exact matches of a string in my 1Password vault but I've confirmed that it will not locate all instances of that string within a vault, even though I've selected 'All Items' for the vault and the Find filter box says "Find in All Items" as the defaulted, greyed out text in the field. This is without even adding special characters to the search string which seems to confuse both the Search and the Find filter functions. So frustrating to be unable to find exact matches of strings/values in 1Password (Mac 8.10.58)
