All search options on this page work with indexed,
unindexed and combination" indexed/unindexed
searching. |

Basic Search Types
|
 |
Phrase searching
finds phrases like: due
process of law. |
|
Boolean operators like and/or/not can join words
and phrases: due process
of law and not (equal protection
or civil rights). |
|
Proximity searching finds a word or phrase within
"n" words of another word
or phrase: apple pie w/38
peach cobbler. |
|
Directed Proximity searching finds a word or phrase "n" words
before another word or phrase:
apple pie pre/38 peach
cobbler. |
|
Phonic searching finds words that sound alike,
like Smythe in a
search for Smith.
|
|
Stemming finds variations on endings, like applies,
applied, applying
in a search for apply.
|
|
Numeric range searching finds any number between
two numbers, such as between
6 and 36.
|
|
Macro capabilities make it easy to include frequently
used items in a search request.
|
|
Wildcard support allows ? to hold a single letter
place, and * to hold multiple
letter places: apple*
and not appl?sauce. |
|
| |
|
|
| |
Fuzzy
Searching
|
|
Fuzzy searching uses a proprietary algorithm
to find search terms even
if they are misspelled. |
|
Search fuzziness adjusts from 0 to 10 so
you can fine-tune fuzziness
to the level of OCR or typographical
errors in your files. |
|
A search for alphabet with a fuzziness
of 1 would find alphaqet;
with a fuzziness of 3, it
would find both alphaqet
and alpkaqet. |
|
Fuzziness is not built into the index, so
you can vary fuzziness at
the time of each search. |
|
| |
|
|
| |
Concept / Synonym
/ Thesaurus Searching
|
|
Concept searching lets you look for fast
and find quick, speedy,
etc. |
|
dtSearch offers variable levels of automatic
synonym expansion based on
a comprehensive semantic network
of the English language. |
|
You can also add your own thesaurus terms.
|
|
| |
|
|
|
Combining Search
Types
|
|
Nearly all search types are combinable. |
|
You can make your search request as complex
as you want. |

| Relevancy-Ranking |
|
| |
|
|
dtSearch can sort and instantly re-sort searches
by relevancy
with respect
to number
of hits, file
name, file
date, etc. |
|
Natural language
algorithms
provide automatic
term weighting,
following
a "plain English"
or unstructured
indexed search
request. |
| |
|
Automatic term
weighting
is
based
on
the
frequency
and
density
of
hits
in
your
files. |
|
For example, in the search request get
me
Sam's
memo
on
the
1999
CorpX
takeover,
if
1999
appeared
in
3,000
files,
and
Sam
appeared
in
only
two
files,
then
Sam
would
get
a
much
higher
relevancy
rating,
taking
you
straight
to
the
most
"relevant"
files. |
|
| |
|
dtSearch also includes variable term weighting
options for
both indexed
and unindexed
searches: |
| |
|
Positive term weighting can place extra
emphasis
on
one
or
more
words:
soup:8
or
recipe:3 |
|
Negative term weighting can assign negative
emphasis
to
one
or
more
words:
red
or
green
or
yellow:-7
|
