Hi Gary, The comparison fails because you're comparing text nodes to strings. Try replacing /text() with /fn:string().
On a more general note, you rarely want to use the text() selector; fn:string() is almost always a better choice: https://developer.marklogic.com/blog/text-is-a-code-smell.

I’m having an issue comparing sequence of strings: let $seq1 = (‘a’,’b’,’c’) with the results of a query let $seq2 := cts:search(doc(), $cqf, "unfiltered")/doc/value/text() but this finds no results when it should: let $intersection := distinct-values(seq1 [.=$seq2]) The intersection between two manual sequences works. What am I missing? Thanks, Gary
