Search This BlogDownload DtSearch Desktop v7.70.8032DtSearch Desktop provides instant searching of desktop-accessible files. dtSearch can instantly search terabytes of text because it builds a search index that stores the location of words in documents. Indexing is easy — simply select folders or entire drives to index and dtSearch does the rest. Once dtSearch has built an index, it can automatically update it using the Windows Task Scheduler to reflect additions, deletions and modifications to your document collection. Updating an index is even faster, since dtSearch will check each file, and only reindex files that have been added or changed.The dtSearch indexer automatically recognizes and supports all popular file formats, and never alters original files. 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 CD/DVDs.Features:A scrolling word list, for instant feedback as you type in a search.A look-up word feature, detailing the effect of fuzzy, phonic, wildcard, stemming and thesaurus search options.Browse and customize thesaurus options.A field button, showing all indexed document fields.A search history display.Search reports, showing hits in retrieved documents, along with the requested amount of context.Clipboard options, file launching, and other tools for working with retrieved data.Exporting of search results in various data formats, for easy use with other programs.Special forensic indexing and searching toolsOS : Windows AllFile Size : 44 MBDOWNLOAD

DtSearchNetStdApi.dll provides a .NET Standard API to use the dtSearch Text Retrieval Engine.dtSearchNetStdApi.dll implements a .NET wrapper around the dtSearch Text Retrieval Engine. To use this API in a .NET project, add dtSearchNetStdApi.dll as a reference, and add the native library or libraries for the platforms that you will support, as described below. For overview topics covering indexing, searching, the dtSearch query language, etc., see Overviews. .NET Standard .NET Standard is a common set of .NET APIs across all .NET platforms. For more information about .NET Standard, please see: Platform compatiblity matrix Native Libraries The dtSearch .NET Standard API consists of two components: (1) dtSearchNetStdApi.dll, which is cross-platform, and (2) a platform-specific dynamic library, dtSearchEngine.dll (Windows), libdtSearchEngine.so (Linux), or libdtSearchEngine.dylib (MacOS). dtSearchNetStdApi.dll is the same on all platforms, and uses PInvoke to call the native library. For information on adding the required native library to your project, see Native Libraries. Deployment For information on deployment of the dtSearch .NET API, please see "Installing the dtSearch Engine with your Application" in the Overviews section. IDisposable When using the dtSearch Engine API, it is essential to use the IDisposable pattern with all API objects except JobErrorInfo. Otherwise, the .NET garbage collector may take a long time to free memory used by potentially large objects such as SearchResults, resulting in memory depletion in long-running applications. In C# code, use a "using" clause with dtSearch Engine API objects, and in other code call Dispose() when you are done with an object.

Article: dts0220 This article will explain how to implement a web-Based search interface for a web site using the dtSearch Engine's .NET interface. Complete sample code for the interface described here is included with the dtSearch Engine in the examples\asp.net4 folder, in C# and VB.NET. Another sample using ASP.NET Core/5/6 and the dtSearch Engine's .NET Standard API is included with the dtSearch Engine in the examples\NetStd\WebDemo, and is online here. Indexing the web site To index the web site, you can either use the dtSearch Desktop Indexer or you can use the .NET API. To build the index using the dtSearch Indexer, 1. Click Start > Programs > dtSearch Developer > dtSearch Indexer. 2. Click Create index (advanced)... 3. Enter a name for the index and check these two boxes under Indexing options: Cache document text in the index and Cache documents in the index. Caching text in the index makes display of hits-in-context in search results much faster. 4. Click OK, then click Yes when the indexer asks if you want to add documents to the index. 5. Click Add web... and add the starting URL for the web site(s) to be indexed. For more information on building indexes of web sites, see How to index a web site with the dtSearch Spider and How to use dtSearch Web with dynamically-generated content. To index a web site using the API, you would use the HttpDataSource class. The following is from the SpiderDemo sample included with the dtSearch Engine: // Set up an IndexJob to build the index indexJob = new IndexJobWeb; indexJob.ActionCreate = true; indexJob.ActionAdd = true; indexJob.IndexPath = IndexPathEdit.Text; indexJob.IndexingFlags = IndexingFlags.dtsIndexCacheText | IndexingFlags.dtsIndexCacheOriginalFile; // Make data source to crawl the web sites dataSource = new HttpDataSourceWeb; foreach (WebSite ws in webSiteList) { dataSource.Add(ws); } // Start the Spider dataSource.StartCrawlWeb; // Attach the Spider's DataSource to the IndexJob indexJob.DataSourceToIndex = dataSource; // Start indexing. indexJob.ExecuteInThreadWeb; Searching the index To search the index for a user-entered search request, set up a SearchJob with the search request and the index to be searched: sj.Request = SearchRequest.Text; sj.IndexesToSearch.Add("... index path goes here ...."); sj.ExecuteWeb; // Get the results of the search Results = sj.Results; ... The search form for the search_cs sample provides additional options for search features such as fuzzy searching, boolean searching, etc.: Transferring these form variables into the SearchJob is done in the DoSearchWeb method of the search_cs sample. When the SearchJob is executed, the results are returned as a SearchResults object. Displaying search results The search_cs sample displays search results in a DataGrid control, showing the name and other properties of each document along with a brief snippet of text (the "synopsis") showing the first few hits

Sound alike (like Smith and Smythe) thesaurus searching, to find related concepts and synonyms, using dtSearch Web's built-in thesaurus and/or user-defined concepts or synonymsWhile dtSearch Web supports all of these search options, Webmasters can easily customise published Web pages to include or exclude any of these options.DisplayAfter a search, dtSearch Web will display retrieved files with hit highlighting, and all links and images intact. The result looks just like the original HTML or PDF page, but with highlighted hits. HTML links remain fully functional in the document. "next hit", "previous document", "next document" buttons let you quickly navigate through your hits and documents.For XML, you can perform indexed searches using the full range of dtSearch features across an entire XML database, or limited to a highly specific combination of fields or sub-fields.For other file types, dtSearch uses built-in file converters to convert non-Web-ready formats such as wordprocessor, database, spreadsheet, ZIP, etc., to HTML for display with highlighted hits.Updates & Support

How dtSearch Works on the WebdtSearch Web uses an index that it builds to search instantly through Terabytes of text. Just select the folders that you want to index, dtSearch automatically recognizes and supports all popular file formats, and never alters or moves your original files.RequirementsdtSearch Web requires IIS 4 or later. IndexingSelect "Add Folder..." as shown below. Once dtSearch has built an index, it can automatically update it using the Windows Task Scheduler to reflect additions, deletions and modifications to your document collection.There is no limit on the number of folders (or individual files) that dtSearch Web can index. You can have dtSearch Web index all of your drives and folders in one index, or you can create separate indexes for groups of related documents. Indexes can overlap -- i.e. the same documents can be placed in separate indexes.Web SetupWith a few mouse clicks, dtSearch Web Form Builder lets you designate multiple indexes to search on your site, and automatically generates a search page. The Form Builder lets you customise the contents of search results, the document display, and the search form itself. (You can also use an HTML editor such as Dreamweaver to edit the search form.)SearchingThe form builder will automatically install the search form on your Internet or Intranet Web site, so visitors can instantly carry out a search.Search OptionsdtSearch Web supports the following search options: single word, phrase and boolean (and, or, not) All the words, Any of the Words, Exact Match. Built-in relevancy-ranking by "hit" density and rarity (so that words which appear more rarely in your documents will receive a higher relevancy ranking) fuzzy searching, adjustable from 1 to 10, to sift through typographical or spelling errors stemming, to automatically find different word variations (like find, finds, finding) phonic searching, to find words that
