When you do a keyword search:
- Results get weight points per keyword match for specific content types (eg. a product title match or a contributor name match)
- Points are accumulative and result in the total weight. You can have multiple matches. For example, a keyword search for ‘Feeding Carroll’ will give you points for both the contributor match and the title match.
- Exact matches get more points than a partial match an inverse match. An inverse match is when you, for example change the word order of the title
- Books within the result set get boost points for certain items of a book:
- The publication date, more recent gets more points, key authors
- Key authors, the publisher can share a set of authors which receive more points
- Books with get points for each format → more is better.
- Books with get points for each review → more is better.
- Books with get points for each asset → more is better.
- Books with get points for each award → more is better.
- Books can get positive boost points or a negative penalty when there is a cover present or when there is one absent
- Results are ordered by weight size, so results with higher points appear higher in the result, this order is called relevance

- Contributor Name : 300 points
- Product Title : 100 points
