Thanks Adrien for reply.
My script filter was,
===================
{
"script": {
"script": "xyz",
"params": {
"startRange": 1407939675, // Timestamp in
milliseconds ... keep changing on all queries
"endRange": 1410531675 // Timestamp in
milliseconds..... keep changing on all queries
},
"lang": "native",
"_cache": true // I removed this caching and i
found significant performance improvement... do you know why ? :-)
}
},
===============================================================================================
My Native(Java) script code // Return true if date ranges overlaps.
====================
===========================================================================
ScriptDocValues XsDocValue = (ScriptDocValues) doc().get(
"start_time");
long XsLong = 0l;
if (XsDocValue != null && !XsDocValue.isEmpty()) {
XsLong = ((ScriptDocValues.Longs) doc().get("start_time"))
.getValue();
}
ScriptDocValues XeDocValue = (ScriptDocValues) doc().get("end_time");
long XeLong = 0l;
if (XeDocValue != null && !XeDocValue.isEmpty()) {
XeLong = ((ScriptDocValues.Longs) doc().get("end_time"))
.getValue();
}
if ((endRange >= XsLong) && (startRange <= XeLong)) {
return true;
}
===========================
