Why Can't I Find Certain Objects in a Bucket When I Searched for Them?

On OBS Console and OBS Browser, you can search for objects by object name prefix. For example, if you search for test, you will find all objects whose names start with test. However, if the keyword entered is in the middle or at the end of the object name, the search will not return those results. For example, the name of the object to be searched for is testabc and you enter abc in the search box, testabc will not be found. Only objects whose names start with the prefix abc are found.
