/**
* Indexes several content objects.

* Notes:
* - Does not force a commit on solr, depends on solr config, use {@see commit()} if you need that.
* - On large amounts of data make sure to iterate with several calls to this function with a limited
* set of content objects, amount you have memory for depends on server, size of objects, & PHP version.
*
* @todo: This method, {@see purgeIndex}, & {@see commit()} is needed for being able to bulk index content.
* However it is not added to an official SPI interface yet as we anticipate adding a bulkIndexDocument
* using eZ\Publish\SPI\Search\Document instead of bulkIndexContent based on Content objects. However
* that won't be added until we have several stable or close to stable advance search engines to make
* sure we match the features of these.
* See also {@see Solr\Content\Search\Gateway\Native::bulkIndexContent} for further Solr specific info.
