Comment 7 for bug 1655125

Nextcloud has several default internal applications included in the product when it is deployed/installed. It also accepts other applications created by any user to perform whatever is needed. Nextcloud snap, when installed, sets a path into its common folder for those extra apps. It is supposed to have every extra app in a separated snap from the nextcloud one. So, the requirement should be having "myapp" snap be able to deploy the app in the nextcloud snap common folder somehow, so that nextcloud can make use of it.
In the specific case of search support, Solr is the server where the documents index is held and nextant is the application to be deployed in nextcloud common folder path. (or communicated with nextcloud using content interface)
