I have seen something like that before and adjusted the code after as this is highly confusing. Not totally sure if this is the case here but maybe someone else can provide more info.

Its probably a typo and could be interpreted in one of three ways.

If search value is boolean and pi.GetValue returns a boolean, it could be:

searchValue = searchValue == pi.GetValue(searchCriteriaViewModel);

Another case is that the original developer was either trying to set two variables to the same value:

searchValue = otherSearchValue = pi.GetValue(searchCriteriaViewModel);

Or it could be that the original developer just put searchValue in twice by accident or copying and pasting one to many times. If that method is working properly at the moment, I would assume the last scenario and remove one of the searchValue assignments.
