Field Search is a suite of software products developed by the National Law Enforcement and Corrections Technology Center (NLECTC). Field Search was designed specifically for use in the field by non-technical criminal justice personnel to allow them to quickly and efficiently search a target computer and create a detailed report of findings. Access to FieldSearch is strictly for law enforcement and corrections professionals. Field Search for Windows® (FS-Win) runs live in a native Windows environment. Similarly, Field Search for Macintosh (FS-Mac) runs live in the native Mac OS X® environment. This approach provides a fast, powerful, yet easy method of examining and monitoring computer use. In essence, Field Search blends preview functions with evidence gathering and reporting functions.

Originally designed to assist probation and parole officers in sex offender management, the Field Search suite is equally effective in first responder situations or in examining computers for evidence of other crimes.


Field Search quickly finds evidence such as Internet histories, images, multimedia files and results from text searches and easily populates a report of the findings. Click here to learn more about Field Search’s features and to view sample screenshots:

Current Versions:

FS Win, Version 5.0: Released January, 2016

FS-Win 5.0 provides users with the following new capabilities:

  • Fully compatible with Windows 8 and 10. Field Search now handles the new versions of Internet Explorer and Edge browsers.
  • Keyword search now handles the full UTF-8 character set. This means you can enter and search for any word or phrase in any language.
  • In addition to user-defined filters for minimum and maximum file sizes, pictures in the Image Gallery can now be sorted by file size or MAC dates.

  • New chat history tools allow the examination of chat activity for Skype, Windows Live, ICQ, and Yahoo Messenger.
  • New HASH search function provides the ability to scan the drive for “hits” against HASH sets.
