Tool usage guide
The String Contains tool allows you to quickly verify if a specific block of text includes one or more target substrings, helping you filter data and validate content with precision.
Background
An administrator needs to check a server log for critical failure indicators.
Problem
Manually scanning thousands of lines to find 'CRITICAL' or 'FAILED' status entries.
How to use
Paste the log content into the text area and enter 'CRITICAL, FAILED' in the search terms field.
Outcome
The tool identifies if any of the specified error keywords are present in the log, allowing for immediate troubleshooting.
Background
A dataset contains mixed records, and the analyst needs to isolate entries containing specific regional codes.
Problem
Identifying which records belong to specific regions without using complex spreadsheet formulas.
How to use
Input the list of records and set the search terms to the desired region codes (e.g., 'US, EU, APAC').
Outcome
The tool confirms the presence of these codes, enabling the analyst to categorize the data efficiently.
Yes, simply enter your search terms separated by commas in the search field.
By default, it is case-insensitive, but you can enable the 'Case Sensitive' option to enforce strict matching.
When enabled, the tool will only return a positive result if every single term you provided is found within the text.
The tool is designed to handle large blocks of text, though extremely large files may perform better if processed in smaller segments.
No, this is a read-only utility that only analyzes your input to report the presence of specified substrings.
