[André van Toly]

I disabled updating indexes of related destination (and in case of delete events als source) nodes in Lucene. This caused huge unnecessary updates of other nodes related to the scheduled node. While experimenting I found these indexing not needed because the nodes were still in the index.

In the following example I was still able to select licenses and find in advanced search:

<list type="mediafragments">
<mmsq:constraint field="show" value="true" />
.. etc. etc. ..

<mmsq:relatednodes type="licenses">
<mmsq:field name="number" alias="licensenr" />
</mmsq:relatednodes>

</list>
