RetrieveTerms(TextReader, String)

Find words for a more-like-this query former. The result is a priority queue of arrays with one entry for every word in the document. Each array has 6 elements. The elements are:

  • The word ()
  • The top field that this word comes from ()
  • The score for this word ()
  • The IDF value ()
  • The frequency of this word in the index ()
  • The frequency of this word in the source document ()
This is a somewhat "advanced" routine, and in general only the 1st entry in the array is of interest. This method is exposed so that you can identify the "interesting words" in a document. For an easier method to call see RetrieveInterestingTerms(TextReader, String).
