Narrow Results for Wildcard Search in WEBi

[JG432]

Hello, I am using a parameter that is linked to a calculated field as a search bar. The problem I am having is that when I'm searching for a very specific item, it's returning too many unrelated results because of the letters involved. For instance, I have a show title that I'm searching for called 'ION'. When I perform the search, it is returning every word in all of my concatenated data sources containing those letters. Is there a way to narrow the search so all of the other values containing those letters do not show up? I've posted a sample excel file and my calculated field below for viewing. The green entry is my targeted search, the yellow highlighted ones are all what is added when I search 'ION' directly. Thank you as always!

CONTAINS(([SHOW NAME]),([Search Parameter]))
or
CONTAINS(([PASSWORDS]),([Search Parameter]))
or
CONTAINS(([POINT OF CONTACTS]),([Search Parameter]))

why do you use "contains" if you need an exact match ?

The first time around I just concatenated them; [SHOW NAME] + [PASSWORDS] + [POINT OF CONTACTS], but if any one of those columns had empty values (not shown in table above), it would not return a result in the search.
