A common process mistake is assuming that all files are searchable. Today electronic based discovery requires our full text search engines to be able to extract the desired text from a wide variety of different file types, email formats, or the contents of the unallocated space on a hard drive. We usually had transcripts, and eventually optical character recognition (OCR) that was pretty straightforward to use (except for the less-than-perfect OCR results). Twenty years ago, full text searching was pretty simple. Mapping the data landscape may not immediately indicate where the textual “treasure” is located. But some people don’t realize the challenges associated with indexing hundreds, or even thousands, of different file types and data structures. Searching and identifying relevant content is a common process for both electronic discovery and computer forensic investigations.
