How dtSearch Works
* dtSearch can instantly search terabytes of text because it builds a search index that stores the location of words in documents.
* Indexing is easy — simply select folders or entire drives to index and dtSearch does the rest.
** Once dtSearch has built an index, it can automatically update it using the Windows Task Scheduler to reflect additions, deletions and modifications to your document collection.
** Updating an index is even faster, since dtSearch will check each file, and only reindex files that have been added or changed.
* The dtSearch indexer automatically recognizes and supports all popular file formats, and never alters original files.
* A single index can hold over a terabyte of text, and dtSearch can create — and search with a single search request — an unlimited number of indexes.
* Since you may sometimes want to search files that dtSearch has not indexed, dtSearch also does unindexed as well as "combination" searching.
* Searching and document display (like indexing) do not in any way affect original files.
** When dtSearch does an indexed search, it searches directly on the index that it has built.
** An unindexed search, in contrast, searches directly through the documents.
** In either case, when dtSearch displays a retrieved document, it refers to the original document, using information in the index to highlight hits.
