I want to know the equivalent query in "https://data.epo.org/expert-services/index.html" for

(ntxt all "optics" OR ntxt all "optical" OR ntxt all "hmd" OR ntxt all "display") AND (ntxt all "virtual reality" OR ntxt all "VR" OR ntxt all "augmented reality" OR ntxt all "AR") AND (ntxt all "aberration" OR ntxt all "distortion" OR ntxt all "crosstalk" OR ntxt all "mismatch" OR ntxt all "polarization" OR ntxt all "ghosting") AND (nftxt any "waveguide" OR (nftxt any "liquid crystal polymer" AND nftxt any "lcp"))

Dear user,
An equivalent query in GPI, which uses different field denominators, would be:
((TIAB or NAME) = "optics" OR (TIAB or NAME) = "optical" OR (TIAB or NAME) = "hmd" OR (TIAB or NAME) = "display") AND ((TIAB or NAME) = virtual and reality OR (TIAB or NAME) = "VR" OR (TIAB or NAME) = augmented and reality OR (TIAB or NAME) = "AR") AND ((TIAB or NAME) = "aberration" OR (TIAB or NAME) = "distortion" OR (TIAB or NAME) = "crosstalk" OR (TIAB or NAME) = "mismatch" OR (TIAB or NAME) = "polarization" OR (TIAB or NAME) = "ghosting") AND ((WORD or NAME) = "waveguide" OR ((WORD or NAME) = liquid or crystal or polymer AND (WORD or NAME) = "lcp"))

I wonder whether you want to make your search work on applicant and inventor names or only on texts. If the later is true the following query might be better:
(TIAB = "optics" OR TIAB = "optical" OR TIAB = "hmd" OR TIAB = "display") AND (TIAB = virtual and reality OR TIAB = "VR" OR TIAB = augmented and reality OR TIAB = "AR") AND (TIAB = "aberration" OR TIAB = "distortion" OR TIAB = "crosstalk" OR TIAB = "mismatch" OR TIAB = "polarization" OR TIAB = "ghosting") AND (WORD = "waveguide" OR (WORD = liquid or crystal or polymer AND WORD = "lcp"))

Background:
The original query was is in the Espacenet syntax and it runs well when pasted there https://worldwide.espacenet.com/. Please follow this link to see how it works:
(ntxt all "optics" OR ntxt all "optical" OR ntxt all "hmd" OR ntxt all "display") AND (ntxt all "virtual reality" OR ntxt all "VR" OR ntxt all "augmented reality" OR ntxt all "AR") AND (ntxt all "aberration" OR ntxt all "distortion" OR ntxt all "crosstalk" OR ntxt all "mismatch" OR ntxt all "polarization" OR ntxt all "ghosting") AND (nftxt any "waveguide" OR (nftxt any "liquid crystal polymer" AND nftxt any "lcp"))
