Understanding Advanced Search Options
Case Sensitive Search
When enabled, this option ensures that the search operation distinguishes between uppercase and lowercase letters. For example, searching for "Text" with case sensitivity enabled will not match "text" or "TEXT". This is particularly useful when working with programming languages, configuration files, or any content where capitalization matters.
Whole Word Matching
This feature restricts matches to complete words only, preventing partial matches within larger words. For instance, searching for "cat" with whole word matching enabled will find "cat" but not "category" or "concatenate". This is invaluable when you want to avoid unintended replacements in compound words or larger terms.
Regular Expression Support
Regular expressions (regex) provide powerful pattern matching capabilities beyond simple text searches. Our tool supports standard JavaScript regex syntax, allowing you to:
Find numeric patterns (\d+ for numbers)
Match email addresses ([\w\.\-]+@[\w\.\-]+\.\w+)
Identify phone numbers (\b\d{3}-\d{3}-\d{4}\b)
Locate specific word patterns ([A-Z][a-z]+ for capitalized words)
Search for whitespace variations (\s+ for multiple spaces)
Highlight Matches
This visual aid highlights all found instances in your text, making it easy to verify search results before performing replacements. The highlighting updates in real-time as you modify your search parameters, providing immediate feedback on match locations.
