I have a Sharepoint custom list with two columns (Title, Column2) in my Office365 Environment. Column2 is a number field starting from 1 to 1200. I added a Gallery to my Powerapps test applicaiton in the web and set the Items property to the following and received the corresponding results.
Filter(NumberList, Column2>10 && Column2< 14 ) = 3 records
Filter(NumberList, Column2>=1 && Column2<=500 ) = records 1 - 500
Filter(NumberList, Column2>=500 && Column2<=502 ) = 1 record (500)
Filter(NumberList, Column2>=501 && Column2<=502 ) = Zero Records.
Filter(NumberList, Column2>500 ) = Zero Records
According to this article Sharepoint should be delegable with the Filter function...
But, it appears that at least in my version of Power Apps that Sharepoint is not Delegable with Filter. Has anyone seen this behavior?
I have found the same issue ! - Using a tip from a different thread, I had created a new field and gave the first three hundred records a value of 300 and the second three hundred a value of 600 ( This just happenede to suit my data split !)
Filter(NumberList, Column2>300 ) returned zero records
Filter(NumberList, Column2=600 ) returned all records
Strangely enough , I wa going to put this in a seperate post today to ask the question why !!!!!
You are right that the filter function is delegatable in Sharepoint, however, if you look at the second table of the article, it only shows that equal (=) is a delegatable operator. So more than, less than, etc. are not delegatable at this point.
As a potential workaround, you could try to use Mod() to get the remainder of a division and use the filter() with equal sign - would need to add a column to your data source with a formulae RoundUp(Mod(Column2/500)...). Then, if you want to retrieve items 501 to 999, then it would be something like Filter(NumberList, ModColumn = 2); for items 1000 to 1500, it would be Filter(NumberList, ModColumn = 3),etc.
So when I added a third column to my data source called Group and put a group number in there (1 for the first 500, 2 for the second 500, and 3 for the third 500) it will let me filter and pull back each set.

Can we honestly say that this product actually does what it says it does?
Well, I agree that there are still quite serious limitations especially regarding delegatable functions and the 500 items limit, but I hope these will be fixed soon. Maybe someone from the forum / Microsoft has a view on a timeline of when specific functions and operators will be come delegatable? Actaully, that would be useful information even if it is a rough estimate, so people can plan specific features for their apps that require those functions.
@irsimeonov Hopefully but this seems to be following a similar course that I am seeing with several Microsoft products most specifically Sharepoint. Microsoft seems to be quick to come out too early toughting easy and flexible functionality for the average user to get the hype up and falling short on their promises. When they receive pushback the response is usually, "we hear you and are planning on implementing that...". Two problems...a) it shouldve already been there and b) as you noted there is no timelime. Just my .02 cents.
