Category Intelligent Software>Fuzzy Logic Systems/Tools Abstract dtSearch 7.4 is a natural language/fuzzy logic text searching, retrieval and publishing system. 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 compact disk (CD)/digital video disks (DVDs). Product offers over two dozen indexed, unindexed, fielded and full-text search options. dtSearch highlights hits in Hypertext Markup Language (HTML), Extensible Markup Language (XML) and portable document format (PDF) while displaying embedded links, formatting and images. dtSearch converts other file types - word processor, database, spreadsheet, email and full-text of email attachments, ZIP, Unicode, etc. - to HTML for display with highlighted hits. Its built-in Spider adds local or remote web sites (including dynamically-generated content) to your searchable database. Search 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). Fuzzy Searching - 1) Fuzzy searching uses a proprietary algorithm to find search terms even if they are misspelled; 2) Search fuzziness adjusts from 0 to 10 so you can fine-tune fuzziness to the level of optical character recognition (OCR) or typographical errors in your files; 3) A search for alphabet with a fuzziness of 1 would find alphaqet; with a fuzziness of 3, it would find both alphaqet and alpkaqet. 4) Fuzziness is Not built into the index, so you can vary fuzziness at the time of each search. Concept / Synonym / Thesaurus Searching - 1) Concept searching lets you look for fast and find quick, speedy, etc; 2) dtSearch offers variable levels of automatic synonym expansion based on a comprehensive semantic network of the English language; 3) You can also add your own thesaurus terms. Basic Search Types - 1) Phrase searching finds phrases like: due process of law; 2) Boolean operators like and/or/not can join words and phrases: due process of law and not (equal protection or civil rights); 3) Proximity searching finds a word or phrase within "n" words of another word or phrase: apple pie w/38 peach cobbler; 4) Directed Proximity searching finds a word or phrase "n" words before another word or phrase: apple pie pre/38 peach cobbler; 5) Phonic searching finds words that sound alike, like Smythe in a search for Smith; 6) Stemming finds variations on endings, like applies, applied, applying in a search for apply; 7) Numeric range searching finds any number between two numbers, such as between 6 and 36; 8) Macro capabilities make it easy to include frequently used items in a search request. 9) Wildcard support allows ? to hold a single letter place, and * to hold multiple letter places: apple* and not appl?sauce. Note: Combining Search Types - Nearly all search types are combinable and you can make your search request as complex as you want. The dtSearch product line consists of - 1) dtSearch Desktop with Spider - instantly searches files on a PC; 2) dtSearch Network with Spider - searches across a network; 3) dtSearch Web with Spider - quickly publishes a large volume of instantly searchable data to an Internet or Intranet site. The Spider expands the scope of the searchable database beyond a site's own data to content on other sites; 4) dtSearch Publish - offers easy publishing of an instantly searchable document collection to CD, DVD, portable harddrive, and the like. The product can also mirror an existing Web site on CD/DVD; 5) dtSearch Text Retrieval Engine - lets software developers add dtSearch search functionality to Web-based and other applications. The dtSearch Engine also supports databases such as SQL; 6) dtSearch Engine for Win & .Net - supports C++, Java and .NET. The dtSearch Engine for Win & .NET also includes a .NET Spider Application Programming Interface (API), making the Spider functionality accessible to software developers; 7) dtSearch Engine for Linux - provides C++ and Java APIs to software developers.
dtSearch Desktop/dtSearch Network 7.21 and later For information about dtSearch Web requirements, please see these articles: dtSearch Web system requirements and performance? Operating systems supported Windows 98, Windows ME, Windows 2000, Windows XP (through SP2), Windows 2003 Server, Windows Vista (Vista requires version 7.40 or later) Web Browser dtSearch Desktop also requires that Internet Explorer 5 or later be installed. Internet Explorer does not have to be your default browser (you can still use Netscape, Opera, or any other browser). dtSearch just needs certain components that are only available if Internet Explorer 5, 6, or 7 is installed on the computer. Not supported: Windows 3.x (16-bit), Windows NT 3.51 or earlier, Windows NT 4, Windows 95 (due to the lack of support for these platforms in Visual Studio .NET 2005) Hardware Requirements dtSearch Desktop is designed for systems with a screen resolution of 800x600 or higher. Installation takes between 4 and 30 megabytes of hard disk space, depending on the options selected. (There is an optional thesaurus that takes about 20 Mb installed. The thesaurus is used for synonym searching.) Additionally, you should have enough free space on the hard disk to build indexes of your documents. A dtSearch index takes about 1/3 the size of the original documents. Please see the article on Index Size for more information. Recommended memory size is 256 Mb or more. dtSearch itself requires about 10-20 Mb of memory to search. Indexing can be done with as little as 30 Mb but more memory will result in faster performance. Performance Recommendations 1. Do not put dtSearch indexes on a compressed drive or folder. For example, do not use NTFS compression or encryption on dtSearch indexes. dtSearch indexes are internally compressed, so you will not reduce their size much, and operating system file compression can slow index access considerably. (dtSearch performance is not affected much if the documents are stored in a compressed drive or folder. It is only the indexes that should not be compressed.) 2. For best performance, use a defragmentation utility such as Diskeeper to keep your hard disk defragmented, and keep the hard disk at least 25% empty so the defragmentation utility can run efficiently. 3. Index updates will be faster and more reliable if dtSearch Desktop runs on the machine where the index is stored. It matters much less where the documents are located, because dtSearch just needs to read each document once to index it. Manufacturer Home office; see web site for international locations.
