java - Updating a document in Solr using SolrJ -


i have following indexed data in solr. want add field "location" in indexed data using solrj. how can this?

"response":{"numfound":3061,"start":3059,"docs":[       {         "id":12345,         "name":"rajeev kumar",         "_version_":1223434645768768687},       {         "id":67890,         "name":"rohit kumar",         "_version_":1246457656544545434}]   }}

after updating should - 

"response":{"numfound":3061,"start":3059,"docs":[       {         "id":12345,         "name":"rajeev kumar",         "location" : <some value>,         "_version_":1223434645768768687},       {         "id":67890,         "name":"rohit kumar",         "location": <some value>,         "_version_":1246457656544545434}]   }}

i tried - 

  public static void main(string[] args) throws solrserverexception, ioexception {              string urlstring = "http://localhost:8983/solr/gettingstarted";             httpsolrclient solr = new httpsolrclient.builder(urlstring).build();             solr.setparser(new xmlresponseparser());             solrinputdocument document = new solrinputdocument();             hashmap<string, object> value = new hashmap<string, object>();              value.put("set","delhi");              document.addfield("location", value);               solr.commit();     }

but problem creating new document instead of updating old document. in advance.

you have include id part in document values, otherwise solr isn't able find original document update. should uniquekey field.

document.addfield("id", 12345);

you can't perform update against multiple documents in 1 request, each document has updated itself.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
