API get request search parameter automatically appends '%' at the beginning (if startSearch not set) and the end of the search pattern.

By enabling searchWildcardsEnabled parameter it is possible also to insert '%' in the middle of search pattern:

If set to true enables the use of “*” as a wildcard character in the search parameter.

However this case API does not append '%' characters at the start and end of the search pattern, which is not documented.

So either documentation should be updated or API fixed.
