java - Dynamic Filter Building in Elasticsearch -


i building api. have id,name,price in elasticsearch. client provides me input json filters applied.

input 1: below user filtering records id=1 (integer)

{     "filters": {         "id":1     }  }

input 2: user querying records city=tokyo

{     "filters": {         "city":"tokyo"     }  }

java code handling inputs , querying elastic search

        filters = ipjson.path("filters");         iterator<entry<string, jsonnode>> ite = filters.fields();          while (ite.hasnext()) {             entry<string, jsonnode> ele = ite.next();             string key = ele.getkey();             if (ele.getvalue().isint()) {                 andfilter.add(filterbuilders.termfilter(key, ele.getvalue().asint()))              } else if (ele.getvalue().istextual()) {                 andfilter.add(filterbuilders.termfilter(key, ele.getvalue().textvalue()));             }           }

for each key received in filters, checking data type of input value.

i want support columns. want generic solution without checking input data type.

input 3:

{         "filters": {             "city":"tokyo",             "id":3,             "price":134.45         }  }

without handling each field vs data type, want query above filters in elasticsearch java api. how that?

update:

trying send string parameters elastic search, getting below exception

searchparseexception[[project][4]: from[-1],size[-1]: parse failure [failed parse source [{"query":{"filtered":{"filter":{"and":{"filters":[{"term":{"id":"\"1\""}}]}}}}}]]]; nested: numberformatexception[for input string: ""1""]; }     @ org.elasticsearch.action.search.type.transportsearchtypeaction$baseasyncaction.onfirstphaseresult(transportsearchtypeaction.java:233) ~[elasticsearch-1.4.1.jar:na]     @ org.elasticsearch.action.search.type.transportsearchtypeaction$baseasyncaction$1.onfailure(transportsearchtypeaction.java:179) ~[elasticsearch-1.4.1.jar:na]     @ org.elasticsearch.search.action.searchservicetransportaction$23.run(searchservicetransportaction.java:565) ~[elasticsearch-1.4.1.jar:na]     @ java.util.concurrent.threadpoolexecutor.runworker(threadpoolexecutor.java:1142) ~[na:1.7.0_60]     @ java.util.concurrent.threadpoolexecutor$worker.run(threadpoolexecutor.java:617) ~[na:1.7.0_60]

when use termfilter filterbuilder dont need specify values explicitly supports basic primitive java types such (float,int,long,string,object). use filterbuilders.termfilter(key, ele.getvalue()) , apache lucene engine takes care of type.

i have method allows user access comment have made on site. have post method lets them update comment. my normal solution send entire comment model through, let them update it, update on database when post back. involve sending commentid through in hiddenfor , can manipulated. how can verify commentid sent in get method same i'm getting in post , not able alter comment wish? how can verify commentid sent in method same i'm getting in post? basically have validate following things in post - user logged-in user. authenticated users post comments. commentid in post , should valid commentid , should present in database. userid associated logged-in user should same userid associated comment . comment should contain userid column, can check @ time of update. to make sure update happens comment has been sent in get - hold commentid in session , in post action compare commentid value in session .
