Display and Compatibility

Display

	dtSearch displays retrieved files with highlighted hits in XML, HTML, PDF, Unicode, ZIP, word processor, database, spreadsheet, email, etc.
	For HTML and PDF, the result looks just like the original Web-based document, but with highlighted hits as well as all links and images intact.
	dtSearch will automatically un-ZIP and display files within a ZIP archive
	dtSearch provides multiple 'hit' and file navigation options like "next hit", "previous hit" and "next document" to guide the user through the document collection.

Technical Note
When dtSearch does an indexed search, it searches directly on the index that it has built, without reference to the underlying documents. An unindexed search on the other hand searches directly through the documents. When it displays a retrieved document, it refers to the original document, using information in the index to locate hits. For example, to display a file indexed with the dtSearch Spider, dtSearch Desktop will return to the Web site to access the document.

dtSearch returned to www.frb.gov to display this document indexed by the dtSearch Spider.

dtSearch displays HTML through a browser interface, including highlighted hits and fully-functional embedded links and images. PDF documents are displayed through a combination browser / Adobe Reader interface, showing images along with highlighted hits.

When dtSearch displays a retrieved document in any other format, it converts it "on-the-fly" to HTML for browser display with highlighted hits.

dtSearch Web nested-field search of Shakespeare XML database.

Other Compatibility
Indexing and searching 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.

When dtSearch displays a retrieved document, it refers to the original document, using information in the index to locate hits. Like indexing and searching, document display does not in any way affect the original files.

	dtSearch generally supports data types such as word processor, database, spreadsheet, email, PDF, ZIP, HTML, XML and Unicode from current file formats such as Office 2000 back to legacy file formats.
	For additional information on XML and other fielded data support, see Fields.
	dtSearch indexes, searches and displays unrecognised file formats as binary text, or through a special proprietary "filtered binary" option.
	Optional file segmentation provides for the treatment of long text files as multiple logical subdocuments (relevant for older legacy data or other long text files such as logs).
	A built-in image viewer in dtSearch Desktop and dtSearch Network also displays popular graphics formats (TIF, GIF, PCX, BMP, JPG, EPS, etc.).

Other Requirements

	Version 6 of the dtSearch product line is 32-bit to run under WIN 95/98/NT/ME/2000. (There are generally no other system requirements, any system running one of these versions of Windows should support dtSearch.)
	dtSearch Web requires a recent version of IIS Server.
