Features — 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. |
|
|
A positional
scoring option works
with dtSearch's natural language relevancy
ranking to rank documents more highly
when hits are near the top of a file,
or otherwise clustered in a file. |
|
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 |
|
|
| Variable
term weighting can also apply to
fields: (description:5
contains (apple and pear)) or (author:2
contains smith) |
