Use the wildcard property to run a wildcard query.

Set the property to a regular expression that includes a wildcard character in the middle or end of a search term:
→Use ? to allow a match to any single character.
→Use * to allow a match to zero or many characters.

For example, you could set the wildcard property to "inter*" to return matches for "interview", "interject", "internal", and so on.

You cannot place the wildcard character at the start of the search term.

If you use the wildcard property, the Search Service does not use any analyzers on the contents of your query text.
