Sini,
Sorry to be late on the uptake on this one.
If we back up to your original question, I *think* what you're saying is that
if you have a collection constraint defined that has a prefix ("/provider/"),
you would expect the metadata extracted for that document using that constraint
reference to be only collections under that prefix, not all collections for
that document.
Is that what you were confused by, and hoping to fix?
If you confirm that's the case, then I think the answer is that there's a bug
in the Search API, and we can file that so that it can be fixed. What version
are you running?

Hi Eric,
How can I get the node name of a particular constraint from the search that I
perform?
for example:
I have a json query, I perform a json:transform-from-json on the query and then
perform a search:resolve on the query with options.
let $jsonQry :=
'{"query":{"and-query":{"queries":[{"collection-constraint-query":{"constraint-name":"type","uri":["flower"]}}]}}}'
let $query := json:transform-from-json($jsonQry,$sut:json-config-query)
let $globalQry := search:resolve($query, $options) (:all the options specified:)
return
$globalQry
Here the $globalQry would return all the search:metadata nodes and the
searc:facet nodes [for all the constraints configured in my options].
So for each of the element/attribute, I can get the possible values.
Similar way, how do I get the node name of a particular node. Will path range
index configuration help?
How do I add a constraint to get the node value in $options?
Thanks,
Sini

Hi, Sini:
The term "metadata" may have created an unhelpful expectation.
In the Search API, metadata extraction gets nodes from the content of the
result document other than the nodes matched by the query criteria. It's
called "metadata" because it's often general information such as the identifier
or title.
Thus, when extracting metadata, the query options can specify only a XML
element or attribute, JSON key, or field (whether directly or indirectly by
reference to a constraint). A collection does not appear in the content of a
document, so the query options can't extract a collection as metadata.
Also, a collection is just a tag associated with one or more documents. A
collection has no metadata to extract.
Can you expand a bit about the goal here?

Subject: [MarkLogic Dev General] Maklogic : get collection Search Metadata
Hi All,
I'm performing a search:resolve operation on a query with options which include
a collection constraint as below.
<search:constraint name="provider">
<search:collection prefix="/provider/" facet="true">
<search:facet-option>frequency-order</search:facet-option>
<search:facet-option>limit=10</search:facet-option>
</search:collection>
<search:annotation><proj:front-page
xmlns:proj="http://marklogic.com/appservices/project"/><proj:side-bar
xmlns:proj="http://marklogic.com/appservices/project";>true</proj:side-bar></search:annotation>
</search:constraint>
How do I get the search:metadata for the collection "provider"?
I have included the below node in the options.
<search:extract-metadata>
<search:constraint-value ref="provider"/>
</search:extract-metadata>
I get the result with all the collection details that exist for the search doc.
Thanks,
Sini
