Search / Fielded Data Divide from a Development
Perspective |
|
| In addition to full-text search
options, dtSearch offers extensive fielded
data support. These
include: |
 |
indexing and
searching of all popular
database formats |
|
special XML and SQL
search features |
|
|
indexing
and searching
of BLOB
data |
|
|
indexing and
searching of fields in all
supported file
types |
|
extensive developer
support for adding on-the-fly
classification information
and other fields to documents
during indexing |
|
| Additional
information: |
|
dtSearch
automatically detects fields
(including document summary
information fields) in a wide
range of
supported
file types
. |
|
In addition to
full-text searching, dtSearch
can also search by field
name: (Author contains
John Smith) and (Subject
contains turbine
generators). |
|
|
Variable
term
weighting can
also apply to
fields:
(description:5
contains
(apple and
pear)) or
(author:2
contains
smith) |
|
|
dtSearch supports
hierarchical field structures
in XML data, including both
fields and attributes,
enabling highly refined
nested field
queries. |
|
The dtSearch Engine
supports SQL, ADO.NET and
COM. |
|
|
| API Options for Data
Classification: |
|
A wide range of API
filters and objects support
categorization via document
full-text contents, document
fielded data, database
content, or data attributes
attached during document
indexing. |
|
For example, search
filter objects work in
conjunction with end-user
query dialects to allow
multiple users with different
security classifications to
search the same document
collection, without having to
maintain separate indexes
corresponding to each
classification
level. |
|
|
A
single query
can include
an “exact
phrase”
full-text
end-user
search
request;
second-level
Boolean
search
expressions
(such as one
or more field
or metadata
search
criteria);
and
developer-added
filtering
expressions
(such as a
filtering
expression to
filter out
documents
that do not
match a
user’s
security
classification). |
