How can I handle duplicated listings returned by the search endpoints? I use both /autosuggest and /discover and I've noticed that some businesses are duplicated with very slight differences in their properties except for their IDs. However in the HERE mobile app, those duplicates don't show up. Specific examples are:

• Pizza 24: the IDs of the duplicates we've seen are here:pds:place:8409q5c3-5b06808fd3b838ae0660eb1d8085822f and here:pds:place:8409q5c3-0d53d37882a748c2aaa58782989b63e5
• Lenzini's Pizza: the IDs of the duplicates we've seen are here:pds:place:8409q5c3-d0bbc81a1b199188ff9194b6ab093ac1 and here:pds:place:8403fv6k-3f99756021610424619424385003db58. The screenshot below from the HERE mobile app shows that all the displayed results are unique places, but these duplicates are for the place at 12740 Culver Blvd, Los Angeles, CA 90066, United States (second place in the screenshot)
• Manhattan Pizzeria: the IDs of the duplicates we've seen are here:pds:place:8409q5bc-16fff9dec3584963a0361aaada0af8c6 and here:pds:place:840jx7ps-ad85328ee4230ae0ea9a64aad3b5af4c

It's clear that there's a way that the HERE team gets around this problem, so I'd like to replicate that for myself if possible. Thanks! :)

Answer 1

Actually #9 On this URL (and a few other fixes) state duplicates

#9 Query for "International Tap House" returns duplicates.

https://developer.here.com/documentation/places/release_notes/topics/resolved-issues.html

However nothing is stating how to fix as per this scenario which is on-the-fly. Where 2 places are same (duplicate) in almost all ways, same address etc but have unique IDs and maybe a slight difference in hrs of operation or something. HERE own all doesn't show both as shown above so there must be a logic mechanism to filter one out (or a best practices suggestion).
