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. |
|
|

|
| |
The
dtSearch product line can instantly search
terabytes of text across a desktop, network,
Internet or Intranet site.
|
dtSearch
products also serve as tools for publishing,
with instant text searching, large document
collections to Web sites or CD/DVDs.
