[TYPO3-Solr] Index field - USER TS type ?

[Michal Cygankiewicz]

Due to complexity of some record type which I need to index (product item, with add to basket functionality etc which I want to present in search results also) I would like to index some field as USER type. Something like that:

plugin.tx_solr.index.queue.courses.fields.wholeItem_stringS .value < productSingleListItem

and before

productSingleListItem < tt_content.list.20.shop_pi1
productSingleListItem  { 
        controller = Product
        action = singleOverview
        switchableControllerActions {
          Product { 
            1 = singleOverview
          }
        }
        settings.productId = 2903
}


But I can not manage to do so. I am completely sure that productSingleListItem returns correct content when testing like that 

page.10 < productSingleListItem 

I am also able to assign other TS types which are indexed correctly then, for example:

textTest = TEXT
textTest.value = test

plugin.tx_solr.index.queue.courses.fields.wholeItem_stringS .value < textTest

So I am wondering if it is not possible to index fields as USER?
