json - Elasticsearch | filter on not related nested data -


ok, today have problem filter elasticsearch query double nested not related fields specs.value.text , specs.spec.text.

the mapping of these fields: 

... "specs": { "type": "nested", "properties": { "spec": {   "type": "nested",   "properties": {     "text": {       "type": "string",       "fields": {         "raw": {           "type": "string",           "index": "not_analyzed"         }       }     }   } },  "value": { "type": "nested", "properties": {   "text": {     "type": "string",     "fields": {       "raw": {         "type": "string",         "index": "not_analyzed"         }       }     }     }   } } } ....

the question when want filter query request:

    {       "query": {         "filtered": {           "filter": {             "and": {               "filters": [                 {                   "nested": {                     "filter": {                       "nested": {                         "filter": {                           "match": {                             "specs.value.text": "10"                           }                         },                         "path": "specs.value"                       }                     },                     "path": "specs"                   }                 },                 {                   "nested": {                     "filter": {                       "nested": {                         "filter": {                           "match": {                             "specs.spec.text": "délai de livraison"                           }                         },                         "path": "specs.spec"                       }                     },                     "path": "specs"                   }                 }               ]             }           },           "query": {             "match_all": {}           }         }       },       "_source": [         "specs"       ]     }

elasticsearch return document contains word délai de livraison in specs.spec.text or 10 in specs.value.text

exemple of result: first object:

  ...   "specs": [       {         "value": [           {             "text": "10",             "lang": "fr-fr"           }         ],         "spec": [           {             "text": "délai de livraison",             "lang": "fr-fr"           }         ]       },         {          "value": [           {             "text": "10",             "lang": "fr-fr"           }         ],         "spec": [           {             "text": "volume",             "lang": "fr-fr"           }         ]       }   ]   ...

the second object:

    ...     "specs": [       {         "value": [           {             "text": "7"           }         ]         "spec": [           {             "text": "délai de livraison"           }         ]       }     ]     ...

the correct query should following

{     "query": {         "bool": {             "must": [{                 "nested": {                     "path": "specs",                     "query": {                         "bool": {                             "must": [{                                 "nested": {                                     "path": "specs.value",                                     "query": {                                         "bool": {                                             "must": [{                                                 "match": {                                                     "specs.value.text": "10"                                                 }                                             }]                                         }                                     }                                 }                             }, {                                 "nested": {                                     "path": "specs.spec",                                     "query": {                                         "bool": {                                             "must": [{                                                  "match": {                                                     "specs.spec.text": "délai de livraison"                                                  }                                             }]                                         }                                     }                                 }                             }]                         }                     }                 }             }]         }     } }

since running 2 nested queries @ specs level, both documents match both documents match each filter in different nested documents under specs. scope , conditions same nested document fire filters under 1 nested query

hope helps ajay

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
