Solr does not index and fail somehow.

Steps to reproduce:

• Install eZ Platform 2.0.1 through eZ Launchpad
• ~ez init (enter enter enter)
• open http://localhost:42080/admin/
• login admin/publish
• create a new article underneath the Top Node
• you should be redirected to http://localhost:42080/admin/content/location/54
  => which is the new Article
• go back on the Top Node

Expected Result: I should see my new Article in Sub Items
Result: I don't see the new Article in Sub Items.

Then go on the Solr Interface and search something
http://localhost:42983/solr/collection1/select?indent=on&q=test&wt=json
An error is displayed:

{
  "responseHeader":{
    "status":400,
    "QTime":0,
    "params":{
      "q":"test",
      "indent":"on",
      "wt":"json"}},
  "error":{
    "metadata":[
      "error-class","org.apache.solr.common.SolrException",
      "root-error-class","org.apache.solr.common.SolrException"],
    "msg":"undefined field _text_",
    "code":400}}

Error: undefined field text

Then stop and star solr

ez stop solr; ez start solr

Go back on the Top Node http://localhost:42080/admin/content/location/2
The subitem appears.

But the search is still in error:
http://localhost:42983/solr/collection1/select?indent=on&q=test&wt=json

And new created content won't show up.

That is a 10min reproductible bug.

Thank you for your help!

Update: This issue is not reproducible on clean eZ Platform EE v2.0.1 with Solr 6.6.0 in the local environment. Seems like this is eZ Launchpad related bug.
