When reindexing on Sitecore 9.1, a folder with all the images is created ..\App_Data\mediaIndexing. My problem is that it gets very big in size, > 55GB of images in my case. Has anyone encountered this problem because I couldn't find anything about this.

  • interesting! I have never seen mediaIndexing folder :) Sep 24, 2019 at 17:45

This is done as part of the extraction of the content of media items for the _content field. See for example Sitecore.ContentSearch.Solr.DefaultIndexConfiguration.config where it has the type Sitecore.ContentSearch.ComputedFields.MediaItemContentExtractor,Sitecore.ContentSearch. The file mapping is done in the node at contentSearch/indexConfigurations/defaultSolrIndexConfiguration/mediaIndexing. If you would like to disable this, you could create a patch file to remove this field. Something like:

<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
            <fields hint="raw:AddComputedIndexField">
              <field type="Sitecore.ContentSearch.ComputedFields.MediaItemContentExtractor,Sitecore.ContentSearch">
                <patch:delete />
  • Only thing I would add is to be a little careful about removing fieldName="_content" because it is often augmented by custom computed indexers for indexing datasources for exmaple (e.g. kamsar.net/index.php/2014/05/indexing-subcontent). It might be safer to target the type attribute in the patch.

  • Ah, good call, didn't realize people were doing that. Not sure I like the idea of adding multiple entries for _content, but if people are doing it, so be it. Sep 25, 2019 at 3:34
  • That field is used internally and already has indexed data added to it, so it is not uncommon to further augment that data: sitecore.stackexchange.com/questions/8609/…

  • Thank you @MatthewFitzGerald-Chamberlain. Yes, I had to change the fieldName (_content) with type (Sitecore.ContentSearch.ComputedFields.MediaItemContentExtractor,Sitecore.ContentSearch) and it worked.
