DataIdentificationandSearchTechniques·Chapter8 231 Summary Search and identification of potentially relevant ESI can be one of the most challenging phases of the e-discovery process due to the need to fully map, preserve, and potentially search all sources of ESI that are reasonably likely to contain relevant discoverable data. The FRCP was amended in December 2006 to specifically address the challenges of ESI. Though the need to search all ESI sources existed in the rules prior to the amendments, the amendments highlighted the need for you to have a process in place for searching for and identifying potentially relevant ESI across the enterprise. The legal preservation obligation was unchanged by the amendments, but the rules served to underscore the need to search for, identify, and preserve all potentially relevant data sources, including, potentially, voice and video data. To meet your preservation obligation and show a good-faith effort in searching for and identifying potentially relevant information, you must know where your ESI lives across the organization. With multinational organizations, a mobile workforce, and a proliferation of mobile storage devices and media formats, managing your ESI sources has become more important than ever. The early attention require- ments of the FRCP make it essential that you be able to locate potentially relevant data quickly and, in the best of all cases, complete an early assessment of that data. Although building a data map can be daunting, in the end the data map will help ease the challenges of searching for and identifying your data. You must also carefully consider and select the right tools and techniques for search and identi- fication. These may include legacy methods such as keyword and Boolean searches, or advanced methods such as mathematically based conceptual analysis. Although no one method of search and
