org.terrier.utility.FieldScore

A class for modifying the retrieval scores of documents, according to whether the query terms appear to any of the fields, or tags specified by the property FieldTags.process. These tags can be either HTML tags or tags such as DOCHDR, from the documents.
If a query term appears in any of the specified tags, then the document score can be altered according to the values specified in the property field.modifiers. For example, if FieldTags.process=TITLE,H1,B and field.modifiers=0.10,0.00,0.00, then if a query term appears in the title of a document, the document's score will be increased by a factor of 0.10. @author Douglas Johnson, Vassilis Plachouras

    FieldScore fScore = new FieldScore();
    fScore.insertField(field);
    int fieldScore = fScore.getFieldScore();
    if (fieldScore == 0) 
      return numOfModifiedDocs;
    
    //for each document that contains the query term, the score is computed.
    //int docFieldScore;
