Hi, Sini:
search:resolve() and search:search() both return a <search:response> element,
not a document wrapping the search:response element.
If you are setting $searchResults to the return value, the XPath will fail
because it searches for search:response inside itself.
This can be tricky to diagnose because the document node has no output.
Sometimes it can be useful to do an xdmp:log() of xdmp:node-kind() on the
context node of the XPath just to check where the matches will start. Please
see:
http://docs.marklogic.com/xdmp:node-kind
Anyway, try
return $searchResults/@total/string()
That said, on the general point, if you are searching twice (once to get the
estimate and again to get the actual results), it would be far better just to
set the maximum statically to the largest number you can reasonably process.
By data type, the result ceiling can be set to the maximum unsigned long, but
as Damon has noted, that's unrealistically large.
Hoping that's useful,
Erik Hennum

Hi Eric,
I get the search results as below (return $searchResults)
<search:response snippet-format="snippet" total="69" start="1" page-length="10"
xmlns:xs="http://www.w3.org/2001/XMLSchema"; xmlns=""
xmlns:search="http://marklogic.com/appservices/search";>
<search:result ......
........
........
</search:response>
Why is that, it is not returning any value when I perform the below return
statement ?
return $searchResults//search:response/@total/string()
Thanks,
Sini

Hi, Sini:
I neglected to mention a couple of points that might be useful.
The search response has a total attribute that provides the estimate.
I assume you are writing XQuery in QueryConsole to prototype some client code.
If that's not the case, you might consider stating the query in XML rather than
in JSON to skip the transform step and thus simplify the processing.

Hi, Sini:
If you need to return all results, you could increase the page length in the
query options to the largest number of results that you would reasonably want
to return.
Hoping that helps,
Erik Hennum

Subject: [MarkLogic Dev General] search:estimate
Hi All,
I'm trying to get the total number of results returned after executing a query.
The below code is working fine, but returns only 10 results (default
page-length). But the total result count is 69.
(:All the import statements are provided :)
let $exportQuery :=
'{"query":{"and-query":{"queries":[{"range-constraint-query":{"constraint-name":"city","value":["Paris
01"]}}]}}}'
let $options := xdmp:http-get("http://localhost:6024/v1/config/query/all";,
<options xmlns="xdmp:http">
<authentication method="digest">
<username>admin</username>
<password>admin</password>
</authentication>
<format xmlns="xdmp:document-get">xml</format>
</options>)//search:options
let $query := json:transform-from-json($exportQuery,$sut:json-config-query)
let $searchResults := search:resolve($query, $options)
return $searchResults
I was trying to use the "search:estimate" command to get the total count of
results. But when I execute the command
let $totalItems := search:estimate($query) (:$query being the same as above
code:)
it is throwing some exception.
How do I use search:parse on this $query, which is transformed from json?
I need the $totalItems to return 69.
Any help on this regard would be helpful.
Thanks,
Sini
