A note about searching: the wildcards
While searching, the string entered will be searched as a whole word or
as part of a word. For example, if you entered “love”, the function will find
“Love” and “LoveSong”, or any other word containing the string “love”.
You can use the wildcards “?” (any single character) and “*” (any sequence
of characters) to search exactly for that string. For example, “*love” will find
“MyLove”, but not “LoveSong”. “??love” will find “Mylove” but not “AllLove”.
Also, if you are looking for words that can be spelled in a slightly different
way, you can use the “?” wildcard to find all occurrences; “gr?y” will find out
both “gray” and “grey”.
