Gnana, The map is a hash map, so I assume the order of the elements is affected by how they get allocated to hash buckets. You could try this instead:
let $x := (1,2,3,4,5, 9) ! xs:string(.) let $y := (2,3,6,7,9, 10, 11, 22, 101) ! xs:string(.) let $mx := map:map() let $add-all := for $i in $x return map:put($mx, xs:string($i), true()) return $y[map:get($mx, .)] You'll need to work a little harder if you really have numeric values because map keys have to be strings. Geert is right that if you can have the database directly return lexicon values, that can be easier. Most lexicon functions have an option now to return data as a map.

I tried with maps but saw some interesting results which I didn't expect. When I perform map1 * map2, the results are ordered in different way than the original sequences. Can you please let me know how map:put works? Will it keeps the keys in sequential manner? I think no. For example: When we try inserting 1,2,3 into a map after printing the keys are ordered as 3,1,2 For just getting the intersect values map's are working as expected but looking at the ordering I want to understand maps in better way.
