Periscope Result Ranker module

The Periscope Result Ranker module provides neural network-based search result ranking functionality used by the Find Bar. It extends the Periscope modules.

Installing

Maven is the easiest way to install the module. Add the following dependency to your webapp. All the other necessary dependencies will be brought in automatically:

<dependency>
  <groupId>info.magnolia.periscope</groupId>
  <artifactId>magnolia-periscope-result-ranker</artifactId>
  <version>1.0</version>
</dependency>

• magnolia-periscope-result-ranker.jar

Configuration

No configuration is required.

Note that the Result Ranker module stores its "memory", essentially what it has learned so far about user preferences, under /modules/magnolia-periscope-result-ranker/persistence. Search result preferences are stored by instance, not by user.

If you delete the persistence node, the system forgets what it has learned and must start from scratch again.

Adding support for Linux armhf or Linux ppc64le

The Result Ranker only supports Linux, Mac OS, and Windows by default.

Note that only 64-bit versions of platforms are supported.

If you use Magnolia from one of the environments below, you must add the corresponding dependencies manually:
