Why Can't I Search for Certain Objects in My Bucket?

On OBS Console and OBS Browser 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 name starts 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, you want to search for testabc and you enter abc in the search box, testabc will not be found. Only objects whose name starts with the prefix abc will be found.
