[TYPO3-Solr] Hook modifyDocuments not working on 'pages'

[Reico Cannella]

Hello
I have a working hook that gets called when i try to index my own 
defined tables. Example

plugin.tx_solr.index.queue {
     tt_content = 1
     tt_content {
         fields {
             content = bodytext
             title = bodytext
             url = TEXT
             url = test
        }
     }
This works.


The problem now is, that this does not work:

plugin.tx_solr.index.queue {
     pages = 1
     pages {
         fields {
             content = pid
             title = pid
             url = TEXT
             url = test
         }
     }
}

I see that the document gets indexed correctly with pid as content + 
title. But the hook does not get called, i get no logs in my Devlog.

Also my devlog gets spammed by this messages "No TYPO3SEARCH markers found".
I thought there is no frontend indexing?

I would like to know if there is another hook that gets called for 
pages? Or why does my hook not get called? And why are there messages 
from FE-Indexing?
