c# - Need help implementing multiple Or conditions in Nest query -


i attempting implement following sql pseudo-code in nest elasticsearch.

i haven't found similar stackoverflow questions matching question or in nest documentation. appreciate direction can provide.

select *  curator..published accountid = 10   , (          (publishstatusid = 3 , scheduleddt > '2015-09-01')         or         (publishstatusid = 4 , publisheddt > '2015-09-01')       )

i've created following elasticsearch query unable translate nest syntax.

get curator/published/_search {   "query": {     "filtered": {       "filter": {         "bool": {           "must": [             {               "term": {                 "accountid": 1781               }             }           ],           "should": [             {               "bool": {                 "must": [                   {                     "term": {                       "publishstatusid": 4                     }                   },                   {                     "range": {                       "publisheddt": {                         "gte": "2015-09-01t00:00:00.000"                       }                     }                   }                 ]               }             },             {               "bool": {                 "must": [                   {                     "term": {                       "publishstatusid": 3                     }                   },                   {                     "range": {                       "scheduledt": {                         "gte": "2015-09-01t00:00:00.000"                       }                     }                   }                 ]               }             }           ]         }       }     }   } }

this nest query passes syntax check last "should" condition appears in resulting elasticsearch query.

var results = this.client.count<data>(c => c     .query(q => q         .filtered(f1 => f1             .filter(f2 => f2                 .bool(b => b                     .must(                         f => f.term(fieldname.accountid, "10")                     )                     .should(s => s                         .bool(b1 => b1                             .must(                                 f => f.term(fieldname.publishstatusid, "3"),                                 f => f.range(m => m.onfield(fieldname.scheduledt).greaterorequals("2015-09-01"))                             )                         )                     )                     .should(s => s                         .bool(b1 => b1                             .must(                                 f => f.term(fieldname.publishstatusid, "4"),                                 f => f.range(m => m.onfield(fieldname.publisheddt).greaterorequals("2015-09-01"))                             )                         )                     )                 )             )         )     ) );

this nest query better matches original elasticsearch query raises following error on 2nd bool: error 51 'nest.filtercontainer' not contain definition 'bool' , no extension method 'bool' accepting first argument of type 'nest.filtercontainer' found (are missing using directive or assembly reference?)

var results = this.client.count<data>(c => c     .query(q => q         .filtered(f1 => f1             .filter(f2 => f2                 .bool(b => b                     .must(                         f => f.term(fieldname.accountid, accountid)                     )                     .should(s => s                         .bool(b1 => b1                             .must(                                 f => f.term(fieldname.publishstatusid, "3"),                                 f => f.range(m => m.onfield(fieldname.scheduledt).greaterorequals("2015-09-01"))                             )                         )                         .bool(b2 => b2                             .must(                                 f => f.term(fieldname.publishstatusid, "4"),                                 f => f.range(m => m.onfield(fieldname.publisheddt).greaterorequals("2015-09-01"))                             )                         )                     )                 )             )         )     ) );

your first query not far off, expression passed second should() needs expression passed first should() (should() takes params func[] filters). here's query (i've used dynamic here generic type):

void main() {     var settings = new connectionsettings(new uri("http://localhost:9200"));     var connection = new inmemoryconnection(settings);     var client = new elasticclient(connection: connection);      var docs = client.count<dynamic>(c => c         .query(q => q             .filtered(f1 => f1                 .filter(f2 => f2                     .bool(b => b                         .must(                             f => f.term(fieldname.accountid, "10")                         )                         .should(s => s                             .bool(b1 => b1                                 .must(                                     f => f.term(fieldname.publishstatusid, "3"),                                     f => f.range(m => m.onfield(fieldname.scheduledt).greaterorequals("2015-09-01"))                                 )                             ),                                 s => s                             .bool(b1 => b1                                 .must(                                     f => f.term(fieldname.publishstatusid, "4"),                                     f => f.range(m => m.onfield(fieldname.publisheddt).greaterorequals("2015-09-01"))                                 )                             )                         )                     )                 )             )         )     );      console.writeline(encoding.utf8.getstring(docs.requestinformation.request)); }  public static class fieldname {     public static string accountid = "accountid";     public static string scheduledt = "scheduledt";     public static string publisheddt = "publisheddt";     public static string publishstatusid = "publishstatusid"; }

produces

this matches query dsl above

html - Outlook 2010 Anchor (url/address/link) -

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
