How Can Regular Expressions Ensure Exact String Matches?

How to ensure accurate string matching?

When searching for specific texts, it is important to match the entire string instead of some string. This ensures that the results are exactly the same as your expected query.

Question:

When the accurate string matching is required, a regular expression is required. It only considers the entire string to fully match the query. For example, when searching for a movie with "Red October", only this specific title should be matched to exclude variants such as "The Hunt For Red October". Answer:

For this reason, the following regular expression can be used:

The regular expression is naturally sensitive to lowercase, which means that the above expression will only match the string that is fully matched (not distinguished and lowercase) with "Red October". In order to further explain this concept, the following example is the example of this expression:

Input:

"Red October"

<code>^Red October$</code>

matching result:

True (fully match)

Input: "The Hunt for Red October"

matching result: FALSE (partial match)

^"symbols represent the beginning of matching text, and the" $ "symbol represents its end. This ensures that the expression is matched only when the entire string is matched with the specified query.
