New block: Recommended Contents

[dfanchon]

Due to the complete refactoring of personalization, current magic queries will be discontinued in rubedo 3.4 in favor of specialized blocks.

The Recommended contents block displays relevant contents based on user history (detailed views) and taxonomies to compute this "you may also be interested in" list.

The block is based on a standard elasticsearch query (limited to contents) combined with the following custom parameters:

• historyDepth (in days)
• historySize (number of significant seen items that will be taken into account)

If not set in the block, history depth will default to 30 days and history size will default to 50.
These two parameters can impact search performance in case of high volume history.

The block propagates two new variables to the search API:

• isMagic (true)
• fingerprint
