 * Content for search should be placed in JSON files in ```db/index``` eg. ```db/index/service-manual.json``` (this is done during the compilation step that adds the manual content to this repository)
 * The rake task ```rake rummager:index``` will post these to the rummager service for inclusion in an index called 'service-manual'
