[TYPO3-Solr] Using tx_solr_viewhelper_AbstractSubpartViewHelper

[Heiko Kromm | Paints]

Hi list, 

are there any examples on how to use the tx_solr_viewhelper_AbstractSubpartViewHelper? 
I found the tx_solr_viewhelper_Facet viewhelper, but I don't see how this works. 

I would like to create a viewhelper for my custom indexed elements. I'm thinking about something like this: 

<!-- ###IF:###RESULT_DOCUMENT.TYPE###|==|myelement### begin --> 
<!-- ###MYELEM:###RESULT_DOCUMENT.UID###### begin --> 
<h1>###MYELEM_ITEM.title###</h1> 
###MYELEM_ITEM.img### 
<!-- ###MYELEM:###RESULT_DOCUMENT.UID### ### end --> 
<!-- ###IF:###RESULT_DOCUMENT.TYPE###|==| myelement ### end --> 

MYELEM should be my own viewhelper and it should set the variable MYELEM_ITEM with data fetched from the database, depending on the uid submitted to the viewhelper. 

I need this, because I want to render some pictures and special fields in the search result and don't want to save them in solr. 

Thanks for any help on the subpartViewHelper 

Regards 
Heiko
