更多信息和选项

  • UpdateSemanticSearchIndex 用更多数据扩展现有的 SemanticSearchIndex，扩大索引的存储和搜索能力.
  • Valid index specifications are:
  • "name"a string matching a named semantic search index
    SemanticSearchIndex[…]a valid SemanticSearchIndex object
  • source 可取的值有：
  • "string"纯字符串
    File["path"]单个文件
    URL["url"]"url" 的文本表示
    CloudObject[…]云对象
    LocalObject[…]本地对象
    ContentObject[…]a content object
    {source1,source2,…}list of sources
  • If index contains annotated sources, each new source should be annotated the same way. »
  • Possible ways to specify annotations include:
  • {source1val1,…}a list of sources and associated values
    {source1,…}{val1,…}a rule between sources and values
  • Accepted forms of annotation values vali include:
  • "string"字符串标签
    <|"tag1"v1,…|>标记和元数据组成的关联
  • UpdateSemanticSearchIndex supports the following options:
  • MethodAutomatic关于方法的详细信息
    ProgressReporting$ProgressReporting是否报告计算的进度
  • 可用 Method<|opt1val1|> 给出详细选项. opti 可取的值包括：
  • "ContextPadding"minimal overlap between chunks
    "MaximumItemLength"maximum length of a text chunk
    "MinimumItemLength"minimum length of a text chunk
    "SplitPattern"Automaticwhere to split long strings
  • The automatic "SplitPattern" tries to split a source text in paragraphs, newlines and words to create chunks between "MinimumItemLength" and "MaximumItemLength".
