Hi Damon,
The number of uniqueIds is somewhat high, so element-values will be rather
larger (1mil+). The control seq ids will be in 1k-10k range "non-sequential".
The missing id's from the control seq likely be in the 100 -1000.
But I'll chk and see.
Thanks..

Paul,
I believe you can range-index the uniqueId, element or attribute, then call
cts:element-values() with the option to return data as a map. You can put your
other sequence into a map also and “subtract” maps via the “-“ operator to get
a fast set difference.
Yours,
Damon

Subject: [MarkLogic Dev General] finding an id that does not exist
4 documents: docA, docB, docC, docD. Each have a unique id field with values:
111, 222, 333, 555 respectively. I have a sequence 111,222,333,444. 444 does
not exist in the document set docA, docB, docC, docD. Is there a faster way of
finding this information. I have looked at a few cts functions but I keep
coming back to recurse through each sequence 111,222,333,444 and do
xdmp:estimate cts:search cts:element-value-query on each value. Fast, but still
takes time. Maybe co-occurrence, if data has multiple id fields?
111-aaa,222-bbb,333-ccc,555-eee
thanks
