Definition

Name of a callback which can be used during the document retrieval process.

Use

The Search Engine passes through this callback a table explaining how the results list (containing the index documents and their scores) was obtained.

The query is processed as follows:

  1. The query generates a list of words used in documents. This list is produced through four search methods which associate query words with words used in documents.
  2. Each word of this intermediate list points itself on a number of documents (those in which it appears).

The interface of the callback function is described in the following parameters:

  • IMPORT
    • VALUE(IT_SCORE_EXPL) TYPE SRTV1_TSCORE_PASS

The lines of the table (which are non-flat) contain the following information:

  • ENTRY (field name)

    Word (descriptor) contained in at least one document.

  • SEARCHTYPE (field name)

    Search method which identified the association between the two words.

  • QUERY_WORD (field name)

    Query word

  • LIST (field name)

    List of documents (those containing the word ENTRY) with their IDs and with the score contribution.

Dependencies

The types used on the interfaces of the callback functions are defined in the ABAP Dictionary or in type pools SRTV and SRTV1.

The query expansion callback is related to this callback.
