What's New in V7.25

• New file parsers for OpenOffice documents, spreadsheets, and presentations (*.sxw, *.sxc, *.odt, *.ods, etc.), covering OpenOffice version 1 and OpenOffice version 2 (the "Open Document Format for Office Applications")
  　
• New file parsers for the Microsoft Office XML formats (Microsoft Word 2003 XML and Microsoft Excel 2003 XML)
  　
• dtSearch.Spider.dll component provides a .NET API for the dtSearch Spider. For API documentation, see dtSearchNetApi.chm. For sample code, see C:\Program Files\dtSearch Developer\examples\cs\SpiderDemo.
  　
• New xfilter search type, "ext", to search only on the filename extension (dot required). Examples: xfilter(ext ".doc") matches file with a .doc extension; xfilter(ext "~.doc") matches file without a .doc extension; xfilter(ext ".") matches file with no extension. This search feature will only work with documents that were indexed with dtSearch 7.2 or later.
  　
• SearchReport supports %%FirstHit%% macro in ContextHeader to indicate the word offset of the first hit in the context block
  　
• dtsIndexCacheTextWithoutFields flag added to IndexingFlags. This flag makes it possible to cache text (for generation of a synopsis to include in search results) without including any of the fields added using the data source API.
  　
• dtsErAccCachedDoc flag added to ErrorCodes. This error code indicates that a document could not be extracted from the document cache in an index (this usually means that the index was created without caching enabled)
  　
• dtsConvertJustDetectType flag added to ConvertFlags, to have FileConverter or DFileConvertJob just detect the file format of a document. The format is returned in FileConverter.DetectedTypeId.
  　
• dtSearch Engine for Linux updated to the dtSearch 7.2 code base; multithreading support added
  　
• dtsReportIncludeFileStart flag added to ReportFlags. This flag causes a block of text from the beginning of the document to be included in the generated search report.
  　
• A new search feature makes it possible to restrict a search to the text of documents (excluding any metadata). To search for text that is not in any field, search for //text contains (search request). Example: (//text contains apple) and (author contains smith)

dtSearch Publish在V7.25版本中的新特征如下所示：

• 为OpenOffice文档, 电子表格和演示文稿(*.sxw, *.sxc, *.odt, *.ods, 等等.)格式提供新的文件剖析器,用于覆盖OpenOffice 1的版本与OpenOffice 2 的版本(“即:打开文档格式为Office应用程序”)
  　
• 为Microsoft Office XML格式提供新的文件剖析器(Microsoft Word 2003 XML和Microsoft Excel 2003 XML)
  　
• dtSearch.Spider.dll控件为dtSearch Spider提供一个.NET应用程序接口。为API文件提供dtSearchNetApi.chm帮助文档，为实例代码提供演示文档，请参阅C:\Program Files\dtSearch Developer\examples\cs\SpiderDemo.
  　
• 新的xfilter搜索类型，“ext” 仅用于文件名扩展搜索上(点请求)。
  　
• 例如: xfilter(ext“.doc”) 与之匹配文件扩展名为.doc; xfilter(ext“~.doc”)与之匹配文件无~doc扩展名; xfilter(ext“.“) 没有扩展的匹配文件。
  　
• 该搜索特征仅运行于文档中。
  　
• SearchReport支持%%FirstHit%% 宏在ContextHeader上下文块中显示第一次点击词的偏移量
  　
• dtsIndexCacheTextWithoutFields标志增加了IndexingFlags。该标志可以读取缓存文本（其大纲内容中包括搜索结果）但不包括任何文件，增加使用数据源API。
  　
• dtsErAccCachedDoc标志增加了ErrorCodes。
  　
• 当一个索引文件在一个缓存区域未被提取时显示错误代码（这通常意味着该索引文件未在缓存区域内启用）
  　
• dtsConvertJustDetectType标志增加了ConvertFlags， 以及征查到的FileConverter或DFileConvertJob文件格式。 此文件格式在FileConverter.DetectedTypeId中被返回。
  　
• dtSearch Engine为Linux升级到dtSearch 7.2 ,增加了多线程支持
  　
• dtsReportIncludeFileStart标志增加了ReportFlags。
  　
• 新的搜索特征可限制搜索文本文件（排除任何元文件）。
  　
• 搜索文本不限制任何领域,查找//全文内容(搜索请求)。 实例：(//text contains apple)和 (author contains smith)
