Hi Sini,
I started a reply yesterday to this that got lost somewhere over Germany.
The JSON you've included looks like one tailored to hit the built app
itself, not the Search API. How did you construct this JSON? It just
doesn't look right to me for any of the APIs that we currently have.
The REST API (and AppBuilder) use the MarkLogic Search API under the
covers. As of MarkLogic 6 you can use the Search API with XML or JSON
configuration.
Here's a JSON query I just grabbed (using firebug) from the oscars
example application.
|{"query":{"qtext":"d","and-query":{"queries":[{"range-constraint-query":{"constraint-name":"award","value"||:["lead-actor"]}}]}}}
|
The URL is was sent to was:
http://localhost:8003/v1/search?format=json&view=all&options=all&start=1&pageLength=10
In order to mimic this in QC, you'd need the "all" options node and the
query above, transformed into XML. I can GET the contents of the "all"
options at
http://localhost:8003/v1/config/query/all
Here's how we transform that query (I don't think this is supposed to be
documented at ML6, because of how we configure JSON-XML transforms --
the magic is in the $config. I'm assuming you want gory details).
There will be a public function for it someday.
xquery version "1.0-ml";
import module namespace json = "http://marklogic.com/xdmp/json"; at
"/MarkLogic/json/json.xqy";
import module namespace sut =
"http://marklogic.com/rest-api/lib/search-util";
at "/MarkLogic/rest-api/lib/search-util.xqy";
json:transform-from-json(
'{"query":{"qtext":"d","and-query":{"queries":[{"range-constraint-query":{"constraint-name":"award","value":["lead-actor"]}}]}}}',
$sut:json-config-query)
I'll paste in the whole search:resolve code now so you can see if you
get what's going on. The options actually used in appbuider apps are
far bigger than what I've included here:
xquery version "1.0-ml";
import module namespace search = "http://marklogic.com/appservices/search";
at "/MarkLogic/appservices/search/search.xqy";
import module namespace json = "http://marklogic.com/xdmp/json"; at
"/MarkLogic/json/json.xqy";
import module namespace sut =
"http://marklogic.com/rest-api/lib/search-util";
at "/MarkLogic/rest-api/lib/search-util.xqy";
let $query := json:transform-from-json(
'{"query":{"qtext":"d","and-query":{"queries":[{"range-constraint-query":{"constraint-name":"award","value":["lead-actor"]}}]}}}',
$sut:json-config-query)
return search:resolve($query, <search:options
xmlns:search="http://marklogic.com/appservices/search";>
<search:constraint name="award">
<search:range collation="http://marklogic.com/collation/";
type="xs:string" facet="true">
<search:facet-option>limit=10</search:facet-option>
<search:attribute ns="" name="award"/>
<search:element ns="http://marklogic.com/wikipedia"; name="nominee"/>
</search:range>
</search:constraint>
</search:options>)
Hope that helps not confuse things more !

I don't want to leave you hanging, but someone from the App Services team is probably
better to answer your questions which are App Builder and REST API specific. My answers
were with respect to how things work "under the hood" in the server itself.

Subject: Re: [MarkLogic Dev General] Search Query
Hi David,
Thanks. I have already gone through the search and rest-api guides. But I'm
still not able to figure out a solution for my requirement.
I have the an application built using app builder. I have done some
customization in the application. The customization is as below:
1. When a user performs a search and clicks on the "Export" link (custom link
created) in the results page, a new document is getting generated in the DB.
2. The new document created in the DB has the json query string as an entry in
it.
Example of the document in DB:
<QueryString>{"text":"","page":1,"facets":{"city":{"constraintType":"range","noShadow":true,"value":["Paris"]}}}</QueryString>
3. Now, what I need to know is, how do I reproduce my search results by
executing this json query string?
4. It is said that the json has to be converted into xml. Which is the function
that I should use, json:transform-from-json() OR xdmp:from-json?
5. If I get an xml format, how do I call the search:search to perform the
query. In the above example, I need to search for city:Paris.
Please help.
Thanks,
Sini

Ultimately AppBuilder ends up using search:search or cts:search in "the back
end" (MarkLogic DB).
JSON is converted to XML to perform the searches.
A good start for understanding search concepts from the server perspective is :
http://docs.marklogic.com/guide/search-dev
JavaScript code in AppBuilder uses the REST API which under the hood uses the
above.

Subject: [MarkLogic Dev General] Search Query
Hi all,
How exactly is the search happening at the backend when we search for a
particular document in the application builder?
Is it in json format or something else. Please calrify.
In the controller.js file, I noticed that the query string formed is in json
format. Is this json query converted into some other format to search the DB?
If I have a json query, how do I search DB with the same.
For example: If i have the json query like below, can I use the same to query
the DB seperately in QC.
{"text":"","page":1,"facets":{"city":{"constraintType":"range","noShadow":true,"value":["Paris"]}}}
Thanks,
Sini
