"Don't worry about a search engine like dtSearch getting a hold of your data. These applications do not send copies of your files, the indexes, search request information, etc. back to dtSearch servers. That is not how these applications work!"

Building an Index. dtSearch products can instantly search terabytes of text because dtSearch builds a search index that stores each unique word and its location in the data.

  • A single index can hold up to a terabyte of data, spanning multiple directories, emails and attachments, online data and other databases. (See supported data types.)
  • dtSearch can build and simultaneously search any number of terabyte indexes.
  • Indexing is easy: just point to the folders or online data you want to index.
  • No need to tell dtSearch what files, emails or other content you have; dtSearch will figure that out for itself.
  • Indexing, searching and display of documents does not alter original files or other data, including Hash values.
  • dtSearch also offers automated indexing via the Windows Task Scheduler.
  • See optimizing indexing of large collections of data for important tips on indexing building.
  • dtSearch products also include a caching option for use with web-based or other remote data.
  • See indexing tips for information on unindexed searching, forensics tips, etc.

Updating an Index. dtSearch can update your indexes by adding only new or updated items, removing deleted items, and compressing the index, without affecting searching.

  • Like initial index building, index updates can also be automated via the Windows Task Scheduler.
  • Updating an index, including through the Windows Task Scheduler, does not lock out individual or concurrent searching.
