{     "template" : "log-*",     "settings": {         "index": {             "number_of_shards": 1,             "number_of_replicas": 0         }     },     "mappings": {         "logevent": {             "properties": {                 "timestamp": {                     "type": "date",                     "format": "dateoptionaltime"                 },                 "message": {                     "type": "string"                 },                 "messageobject": {                     "type": "object"                 },                 "exception": {                     "type": "object"                 },                 "loggername": {                     "type": "string"                 },                 "domain": {                     "type": "string"                 },                 "identity": {                     "type": "string"                 },                 "level": {                     "type": "string"                 },                 "classname": {                     "type": "string"                 },                 "filename": {                     "type": "string"                 },                 "linenumber": {                     "type": "long"                 },                 "fullinfo": {                     "type": "string"                 },                 "methodname": {                     "type": "string"                 },                 "fix": {                     "type": "string"                 },                 "username": {                     "type": "string"                 },                 "threadname": {                     "type": "string"                 },                 "hostname": {                     "type": "string"                 }             }         }     } }

which should applied index matching log-*. 1 of index log-2016.07.28

the template specifies type of linenumber. should change type of such linenumber field default string long. document linenumber string.

this returned document:

{   "took" : 1,   "timed_out" : false,   "_shards" : {     "total" : 1,     "successful" : 1,     "failed" : 0   },   "hits" : {     "total" : 1,     "max_score" : 1.0,     "hits" : [ {       "_index" : "log-2016.07.28",       "_type" : "logevent",       "_id" : "avywvw-k6ghup7t-syll",       "_score" : 1.0,       "_source" : {         "timestamp" : "2016-07-28t09:04:02.8994786z",         "message" : "upload file operation took 600 ms",         "messageobject" : { },         "exception" : { },         "loggername" : "reviewer.web.webapi.groupscontroller",         "domain" : "/lm/w3svc/2/root-1-131141667495593380",         "identity" : "",         "level" : "info",         "classname" : "reviewer.logger.methodtimer",         "filename" : "methodtimer.cs",         "linenumber" : "49",         "fullinfo" : "methodtimer.cs:49)",         "methodname" : "dispose",         "fix" : "locationinfo, username, identity, partial",         "properties" : {           "test" : "123",           "log4net:hostname" : "gbwotiom68052d",           "ip" : "::1",           "log4net:identity" : "",           "log4net:username" : "corp\\gianluca.ghettini",           "log4net:elapsedtime" : "600",           "@timestamp" : "2016-07-28t09:04:02.8994786z"         },         "username" : "corp\\gianluca.ghettini",         "threadname" : "198",         "hostname" : "gbwotiom68052d"       }     } ]   } }

as can see 

"linenumber" : "49",

is still string instead of long

what observe source of document (as sent es) , es never change it. if source contains string value, you'll see string value, if source contains numeric value, you'll see number value in source.

however, way data indexed matters. if mapping declares given field string, field value in source (be number, boolean, string or whatever) indexed string.

if mapping declares given field number , field value in source string, es try coerce string number , number indexed, however, the string in source not changed number.

so, in case, send linenumber string "49", es coerce string "49" number 49 , index number, though, source still contain string "49".

to sum up, if want see number in source, need send number, i.e. "linenumber": 49 instead of "linenumber": "49"

Android volley - avoid multiple requests of the same kind to the server? -

i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response...
