✖

updates the SemanticSearchIndex[…] index with the data in source.

✖
UpdateSemanticSearchIndex[index,{source1, …}]

updates the SemanticSearchIndex[…] index with the collection of sources sourcei.

✖
UpdateSemanticSearchIndex[index,{source1 val1, …}]

associates the new source sourcei to the value vali.

Details and Options

  • UpdateSemanticSearchIndex extends an existing SemanticSearchIndex with additional data, expanding the index’s storage and search capabilities.
  • Valid index specifications are:
  • "name"a string matching a named semantic search index
    SemanticSearchIndex[…]a valid SemanticSearchIndex object
  • Possible values for source are:
  • "string"a plain string
    File["path"]individual file
    URL["url"]the text representation of "url"
    CloudObject[…]a cloud object
    LocalObject[…]a local object
    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"string labels
    <|"tag1"v1,…|>an association of tags and metadata values
  • UpdateSemanticSearchIndex supports the following options:
  • MethodAutomaticmethod details
    ProgressReporting$ProgressReportingwhether to report the progress of the computation
  • Detailed options can be given using Method<|opt1val1|>. Possible values for opti are:
  • "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".
