Following are some key dtSearch developer product line features:

• Terabyte Indexer. dtSearch Desktop and Network can index over a terabyte of text in a single index, spanning multiple directories, emails and attachments, online data and other databases. The products can create and search any number of indexes. Indexed search time is typically less than a second, even across terabytes of data.
• Concurrent, Multithreaded Searching. dtSearch developer products provide efficient multithreaded searching, with no limit on the number of concurrent search threads. For online search, the products can run in a completely stateless manner, making it very easy to scale. A “success story” from Intel® describes dtSearch’s “perfect score” for high-volume web-based concurrent searching:
  The dtSearch Engine multi-threaded indexed search demo achieved 100 percent parallel time in the Intel Concurrency Checker test, indicating full optimization for multi-core hardware ... The relationship between Intel and dtSearch stretches back a number of years ... [and] generates synergies that deliver excellent performance and other benefits to end-customers, including internal customers at Intel. Full write-up
