Thanks Mike.
We planned to go for HTTP Client over XDBC Connection.
I noticed better performance in running the query using Http Client
Connection.
I am facing few other issues.
I am trying to pass the dynamic values in the xquery(inside a xqy file -
search.xqy) as query parameters and as request body from the client.
Original XQuery:
for $a in cts:search(collection("collection_name"),
cts:and-query((cts:element-attribute-range-query(xs:QName("book"),
xs:QName("length"), ">=", 26),
cts:element-attribute-range-query(xs:QName("book"), xs:QName("length"),
"<=", 2620), cts:element-attribute-value-query(xs:QName("chapter"),
xs:QName("name"), ('chap1','chap2','chap3','chap4')))), ("score-simple"))
With dynamic inputs:
let $docMin := xs:integer(xdmp:get-request-field("docMin"))
let $docMax := xs:integer(xdmp:get-request-field("docMax"))
let $chapNames := xdmp:get-request-body()
for $a in cts:search(collection("collection_name"),
cts:and-query((cts:element-attribute-range-query(xs:QName("book"),
xs:QName("length"), ">=", $docMin),
cts:element-attribute-range-query(xs:QName("book"), xs:QName("length"),
"<=", $docMax), cts:element-attribute-value-query(xs:QName("chapter"),
xs:QName("name"), $chapNames))), ("score-simple"))
Client method in java:
public static void searchContent(String queryParamString, String
chapterNames)
throws ClientProtocolException, IOException, SysmanConfigException {
DefaultHttpClient httpclient = constructHttpClient();
HttpPost httpPost = new HttpPost(constructMarkLogicUri("/search.xqy"
+ "?docMin=1&docMax=15600"));// queryParamString
HttpEntity entity = new StringEntity(
"('chap1','chap2','chap3','chap4')");// chapterNames
httpPost.setEntity(entity);
// httpPost.setHeader("Content-Type", "text/plain; charset=UTF-8");
HttpResponse response = httpclient.execute(httpPost);
// Examine the response status
System.out.println("Status " + response.getStatusLine());
// Get hold of the response entity
HttpEntity respEntity = response.getEntity();
if (respEntity != null) {
InputStream instream = respEntity.getContent();
try {
System.out.println("Output " + convertStreamToString(instream));
} catch (Exception e) {
e.printStackTrace();
}
}
httpclient.getConnectionManager().shutdown();
}
Output Trace:

The output is empty, when I try processing the above code.
However if I initialize the chapterNames in the xqy file itself, then I am
able to get back required response.
There is some error in the way the chapterNames variable is set or value
passed for the cts:element-attribute-value-query.
Request your help in identifying the error.
Thanks,
Radhika.

>>> The searched information is then filtered based on a fitness

>>> The execution of the query takes a long time if the dynamic
>>> or-query becomes long (for bigger inputs, the or-query formed
