Steps to reproduce

Install clean version with Solr 

In your solr.config set solr.autoSoftCommit.maxTime value to 20000 instead of 20 by default   **   

#in your .../../ibexa/collection1/conf/solrconfig.xml
<autoSoftCommit>
      <maxTime>${solr.autoSoftCommit.maxTime:20000}</maxTime>
</autoSoftCommit>

create or edit an article. In a RTE field, embed an image

The image is not loaded.

Expected behavior:

The image should be displaced.

NB: This is barely reproductible on a clean install with default parameter. 

FYI: Here is the recommendation from Solr regarding the autoSoftCommit parameter:

The time chosen for autoSoftCommit determines the maximum time after a document is sent to Solr before it becomes searchable and does not affect the transaction log. Choose as long an interval as your application can tolerate for this value, often 15-60 seconds is reasonable, or even longer depending on the requirements. In situations where the the time is set to a very short interval (say 1 second), consider disabling your caches (queryResultCache and filterCache especially) as they will have little utility.
