Marklogic (Nodejs API) - Search documents that match 2 (or more) conditions in object array attribute -


my documents stored in json in marklogic (i remove useless attributes case):

{   documentid: '',   languages: [{     locale: 'en_uk',     content: {       translated: 'true',     }   }, {     locale: 'de_de',     content: {       translated: 'false',     }   }, {...}], }

edit: seem 'useless' attributes cause problems. here detailed object.

{   documentid: '',   /* 4 attrs */,   languages: [{       locale: 'en_uk',       attr: '',       content: {       /* 14 attrs */,         translated: true,         /* 2 or 4 attrs */,       }     }, {       locale: 'de_de',       attr: '',       content: {         /* 14 attrs */,         translated: false,         /* 2 or 4 attrs */,       }     }, {...}   ],   /* 0 or 2 attrs */ }

i try find documents have @ least 1 object in languages locale = 'en_uk' , content.translated = true with

var query =   qb.where(     qb.directory('mydocuments'),     qb.scope(       qb.property('languages'),       qb.and(         qb.scope(qb.property('code'), qb.term('en_uk')),         qb.scope(qb.property('translated'), qb.term('true'))       ),       qb.fragmentscope('properties')     )   );

and 

qb.where(   qb.directory(mydocuments'),   qb.scope(qb.property('languages'),     qb.propertiesfragment(       qb.value(         qb.property('languages'),         qb.and(           qb.scope(qb.property('code'), qb.term('en_uk')),           qb.scope(qb.property('translated'), qb.term('true'))         )       )     )   ) )

but in both cases, query return documents match 2 conditions in whole document, not in each object of languages array.

i read documentation haven't found anything. have ideas how can make query ?

edit: try near query doesn't work. doesn't match documents.

qb.where(   qb.directory(config.marklogicconfiguration.product),   qb.scope(qb.property('languages'),     qb.near(       qb.and(         qb.scope(qb.property('code'), qb.term('ja_jp')),         qb.scope(qb.property('translatedinthelanguage'), qb.term('true'))       ),       1,       qb.weight(0),       qb.ordered(true)     )   ) )

i ask if can change object structure.

edit2: finally, use xquery request correct result. 

xdmp:directory("/product/direcory/")/languages[code eq "ja_jp" , content/translated eq "true"] ! root(.)

in case, use eq content/translated condition because boolean stored string. !root(.): return whole object, not language objects match condition [code eq "ja_jp" , content/translated eq "true"]

try using near-query, 1 of location qualifiers available in structured queries. provide locale , translated queries, specify distance: 1 , ordered: true. note whether works depend on "useless attributes" removed were.

if doesn't work, you'll need introduce layer structure. 

{   documentid: '',   languages: [{     item: {       locale: 'en_uk',       content: {         translated: 'true',       }     }   }, {     item: {       locale: 'de_de',       content: {         translated: 'false',       }     }   }, {...}], }

that's not real pretty, let run container-query.
