Exalead has unveiled new versions of its search software for desktop and workgroup environments--exalead one:desktop 4.5 and exalead one:workgroup 4.5. Especially noteworthy, says Exalead, is the desktop product's unlimited document indexing, which is also a feature in the workgroup offering. (Exalead will continue to offer a free downloadable version of its exalead one:desktop software product that can index up to 100,000 documents.) The company explains that as a standalone product, the desktop version offers unified access to information located on a hard drive, in applications such as e-mail or on the Web. When integrated with exalead one:workgroup, the two products serve as a secure solution for a small business or a department within a larger organization, says Exalead. According to the company, new features in Version 4.5 of each offering include:

• infinite scalability,
• faster query response,
• optimize search speed performance on any PC,
• expanded e-mail client support,
• support for more than 300 file formats,
• rich document preview, and
• optimized support for multicore and multiprocessor PCs.
