So back to my initial requirement of determining if a string contains a particular value or not, we would use the -like operator. See some examples below:. In example 1, the result is false because there are no wildcards, therefore its checking to see if the string matches exactly. This essentially means check if xyz exists at the beginning of the string and then ignore the rest. The rest is then ignored due to the wildcard. Example 4 is essentially a reverse of example 3. Example 5 shows searching for something in the middle of the string by using wildcards on either side of the search term. Description: Containment operator. Tells whether a collection of reference values includes a single test value.
