The metadata to be indexed is a set of key-value pairs. The key, which we called a tag is in the form of "tag_name=tag_value”. The search on tag_name supports 2 kinds of wildcards: *-wildcard and ?-wildcard.

1. *-wildcard: matches zero or more characters
2. ?-wildcard: matches any single character

For example:

Storage: ["abcdefgh", "abcfkh", "abfh", "abfffh", "abfaah"]
Search String: "ab*f?h"
Result: [["abcfkh", "abcdefgh", "abfffh"]]
