How to trigger a tx_news search using typolink

Question

We recently switched from tt_news to Georg Ringers News extension and I - as a novice typo3 coder - need help fixing some typoscript code that was used to trigger context specific searches using typolink.

The old snippet was

typolink.parameter = 649
typolink.useCacheHash = 1
typolink.additionalParams.current = 1
typolink.additionalParams.wrap = &tx_ttnews[swords]=|

The new parameter needs to be &tx_news_pi1 but swords does not work. I can't find documentation or examples how the search value can be set. I searched the code itself and dumb tried my luck with &tx_news_pi1[search]=| but that just shows the default numerical typo3 error "Oops, an error occurred! Code: 2018020814150924e87636" if something cannot be rendered. BTW: The referenced search result page works fine if called using the search form.

Answer 1

After grabbing through the code try &tx_news_pi1[overwriteDemand][search][subject]=|. On the target list you need to allow overwriting of the demand in the plugin flexform!

Answer 2

The solution of Thomas works for me even without the [overwriteDemand] using the search result page as target. Thx.

typolink.parameter = 649
typolink.useCacheHash = 1
typolink.additionalParams.current = 1
typolink.additionalParams.wrap = &tx_news_pi1[search][subject]=|

I really would like to know how this could be grabbed from the code. :-) It seems that I have to learn more about php and the underlying data structure - [search][subject] looks like a kind of array which I didn't expect for that type of parameter.
