3260383 - LMS Library Search Rank Logic

Symptom

Customer wants to know by what condition system determines items' ranking in library search.

Environment

SAP Successfactors Learning

Resolution

The catalog ranked search is to provide a keyword/key phrase search that returns results by the relevance. Users enter word(s) and/or phrases to search for. The results returned will match the search criteria and will be ordered with the closest match at the top.

Search Logic :
-There are 5 columns that are searched on with the following weights applied:
title - 10
description – 1
cpnt+id - 1
cpnt+type+id - 1
qual+id - 1

-An occurrence based search is used for scoring an item, then the weight is applied as a multiplier.

For Example:
Item 1: title (1 match), description (1 match) = 11
Item 2: description (4 matches) = 4
Item 3: title (2 matches) = 20

Search words are tokenized.

  • Each token is searched for within each field using a double wildcard (ex. ‘seb’ matches ‘baseball’);
  • Each phrase is searched for within each field using an exact match.
  • The scores for each search against each field are weighted, then summed to produce a final score for the item.

Note:

The maximum number of items displayed in the dropdown list, when customer type in the keyword is limited to 8.
