Order-preserving search problem?

[JessedeDoes]

For instance: order preserved search based on the example "Ik eet kaas" in CGN: (https://gretel5.hum.uu.nl/example-based-search?currentStep=4&xpath=%2F%2Fnode%5B@cat%3D%22smain%22%20and%20@rel%3D%22--%22%20and%0A%20%20%20%20node%5B@rel%3D%22su%22%20and%20number(@begin)%20%3C%20..%2Fnode%5B@pt%3D%22ww%22%20and%20@rel%3D%22hd%22%5D%2Fnumber(@begin)%5D%20and%0A%20%20%20%20node%5B@pt%3D%22ww%22%20and%20@rel%3D%22hd%22%20and%20number(@begin)%20%3C%20..%2Fnode%5B@rel%3D%22obj1%22%5D%2Fnumber(@begin)%5D%20and%0A%20%20%20%20node%5B@rel%3D%22obj1%22%5D%5D&selectedTreebanks=%7B%22gretel%22:%7B%22cgn%22:%5B%22cgn-na%22,%22cgn-va%22,%22cgn-nb%22,%22cgn-vb%22,%22cgn-nc%22,%22cgn-vc%22,%22cgn-nd%22,%22cgn-vd%22,%22cgn-ne%22,%22cgn-ve%22,%22cgn-nf%22,%22cgn-vf%22,%22cgn-ng%22,%22cgn-vg%22,%22cgn-nh%22,%22cgn-vh%22,%22cgn-ni%22,%22cgn-vi%22,%22cgn-nj%22,%22cgn-vj%22,%22cgn-nk%22,%22cgn-vk%22,%22cgn-nl%22,%22cgn-vl%22,%22cgn-nm%22,%22cgn-vm%22,%22cgn-nn%22,%22cgn-vn%22,%22cgn-no%22,%22cgn-vo%22%5D%7D%7D&retrieveContext=0&inputSentence=Ik%20eet%20kaas&isCustomXPath=0&attributes=~pt::~pt&respectOrder=1&ignoreTopNode=0), no results.

The generated xpath looks OK:

//node[@cat="smain" and @rel="--" and
node[@rel="su" and number(@begin) < ../node[@pt="ww" and @rel="hd"]/number(@begin)] and
node[@pt="ww" and @rel="hd" and number(@begin) < ../node[@rel="obj1"]/number(@begin)] and
node[@rel="obj1"]]

In GrETEL 4 I do get results (https://gretel.hum.uu.nl/ng/example-based-search?currentStep=4&xpath=%2F%2Fnode%5B@cat%3D%22smain%22%20and%0A%20%20%20%20node%5B@rel%3D%22su%22%20and%20number(@begin)%20%3C%20..%2Fnode%5B@pt%3D%22ww%22%20and%20@rel%3D%22hd%22%5D%2Fnumber(@begin)%5D%20and%0A%20%20%20%20node%5B@pt%3D%22ww%22%20and%20@rel%3D%22hd%22%20and%20number(@begin)%20%3C%20..%2Fnode%5B@rel%3D%22obj1%22%5D%2Fnumber(@begin)%5D%20and%0A%20%20%20%20node%5B@rel%3D%22obj1%22%5D%5D&selectedTreebanks=%7B%22gretel%22:%7B%22cgn%22:%5B%22CGN_ID_NA%22,%22CGN_ID_VA%22,%22CGN_ID_NB%22,%22CGN_ID_VB%22,%22CGN_ID_NC%22,%22CGN_ID_VC%22,%22CGN_ID_VD%22,%22CGN_ID_NE%22,%22CGN_ID_NF%22,%22CGN_ID_VF%22,%22CGN_ID_NG%22,%22CGN_ID_VG%22,%22CGN_ID_NH%22,%22CGN_ID_VH%22,%22CGN_ID_VI%22,%22CGN_ID_NI%22,%22CGN_ID_VJ%22,%22CGN_ID_NJ%22,%22CGN_ID_NK%22,%22CGN_ID_VK%22,%22CGN_ID_NL%22,%22CGN_ID_VL%22,%22CGN_ID_NM%22,%22CGN_ID_VM%22,%22CGN_ID_NN%22,%22CGN_ID_VN%22,%22CGN_ID_VO%22%5D%7D%7D&retrieveContext=0&inputSentence=Ik%20eet%20kaas&isCustomXPath=0&attributes=~pt::~pt&respectOrder=1&ignoreTopNode=0)
