[MarkLogic Dev General] Invalid coercion and cts:query

[Colleen Whitney]

Or, since the parsed queries are already serialized, you can construct it directly and save a few milliseconds.

<cts:or-query>
  {$englishQuery}
  {$germanQuery}
 <cts:or-query>

Oh, and one other thing was pointed out to me offline. The search:resolve() function is expecting an element, not a cts:query, so you do actually need to convert the cts:or-query to an element. If you change your third line to the following I think you'll be in good shape.
$query := <tmp>{cts:or-query((cts:query($englishQuery), cts:query($germanQuery)))}</tmp>/element()

Hi Adam,

You don't need that cts:query() wrapper around everything, just use the cts:or-query() directly.

The cts:query() function creates a query from an XML representation of it (e.g. if you had placed a query into a document).

Hi, newbie to XQuery and Marklogic here. I’m trying to do something like the following:



                ...

                $englishQuery := search:parse($queryString, $englishOptions),

                $germanQuery := search:parse($queryString, $germanOptions),

                $query := cts:query( cts:or-query((cts:query($englishQuery), cts:query($germanQuery)))),

                $results := search:resolve($query, bhccSearch:getSearchOptions($target, $page))

                return ...



I have content which is English, and other content which is German, and I am trying to build queries which will search both the English and German content, and then build a cts:or-query from those, and finally build a cts:query from the cts:or-query which I can use with search:resolve to return results. I keep getting errors like this:



XDMP-ARGTYPE: (err:XPTY0004) cts:query(cts:or-query((cts:word-query("pa", ("lang=en"), 1), cts:word-query("pa", ("lang=de"), 1)))) -- arg1 is not of type element()



So I guess the cts:or-query constructor is not returning me an element as needed by the cts:query constructor. Can someone explain why this is and how I should handle this?



Cheers,



Adam
