Marklogic搜索選項來限制搜索一個JSON嵌套屬性

Question

我有具有以下結構

{"scientist":{ 
     "username": "XXX", 
     "name":"XXXX" 
      ... 
    }, 
    "registrar":{ 
     "username": "YYY", 
     "name":"aaaaa" 
      ... 
    } 
    } 

我想限制搜索在如上述JSON搜索嵌套屬性JSON： - 想要搜索「註冊商/用戶名」..我試圖使用搜索-constraint「容器」..但無法執行搜索..以下是我的代碼，它似乎並沒有工作..

是否有任何其他機制的嵌套json字段搜索？

```

let $search := "(username:WHITEMK) AND (concept.registrar:)" 

let $options := 
    <options xmlns="http://marklogic.com/appservices/search"> 
    <constraint name="concept.registrar"> 
     <container> 
     <json-property>registrar</json-property> 
     </container> 
    </constraint> 
    <constraint name="username"> 
     <value> 
     <json-property>username</json-property> 
     <term-option>case-insensitive</term-option> 
     <term-option>wildcarded</term-option> 
     </value> 
    </constraint> 
    <return-facets>false</return-facets> 
    <return-values>false</return-values> 
    <return-constraints>false</return-constraints> 
    <return-frequencies>false</return-frequencies> 
    <return-qtext>false</return-qtext> 
    <search-option>unfiltered</search-option> 
    <search-option>unfaceted</search-option> 
    <search-option>format-json</search-option> 
    <search-option>score-simple</search-option> 
    </options> 

let $start := 1 
let $page-length :=10000 

return search:search($search, $options, $start, $page-length) 

```

我能得到一個更寬泛的版本而無需添加嵌套的領域是建立一個自定義的搜索選項，解析嵌套的JSON財產，並建立使用CTS搜索查詢：JSON-財產範圍查詢..
對於例如：讓我們假設你想尋找一些3級嵌套屬性

let $search := "(concept:orfs.aminoAcids.predictedMatureSeqs.domains.heavyChainIsoType:igg1)" 

使用自定義分析器我能如果有人有興趣下面這個變換以下

<cts:json-property-scope-query xmlns:cts="http://marklogic.com/cts"> 
<cts:property>orfs</cts:property> 
<cts:json-property-scope-query> 
<cts:property>aminoAcids</cts:property> 
<cts:json-property-scope-query> 
<cts:property>predictedMatureSeqs</cts:property> 
<cts:json-property-scope-query> 
<cts:property>domains</cts:property> 
<cts:json-property-scope-query> 
<cts:property>heavyChainIsoType</cts:property> 
<cts:word-query> 
<cts:text xml:lang="en">igg1</cts:text> 
<cts:option>case-insensitive</cts:option> 
<cts:option>punctuation-insensitive</cts:option> 
<cts:option>whitespace-insensitive</cts:option> 
<cts:option>wildcarded</cts:option> 
</cts:word-query> 
</cts:json-property-scope-query> 
</cts:json-property-scope-query> 
</cts:json-property-scope-query> 
</cts:json-property-scope-query> 
</cts:json-property-scope-query> 

是代碼自定義解析器

xquery version "1.0-ml"; 
module namespace gbrsso="http://marklogic.com/gbrs/modules"; 
import module namespace search = "http://marklogic.com/appservices/search" at "/MarkLogic/appservices/search/search.xqy"; 
(: 
    This module tries to build a custom constraint.. and takes into account the nested query as well 
    for eg: Concept:registrar.username:mamidrx 
:) 

(: This is parse function which is invoked my marklogic when it sees the custom constraing :) 
declare function gbrsso:parse($constraint-qtext as xs:string, $right as schema-element(cts:query)) as schema-element(cts:query){ 
let $log := xdmp:log("Constraint-qtext : " || $constraint-qtext) 
let $log := xdmp:log("$right : " || fn:string($right//cts:text/text())) 
let $queryText := fn:string($right//cts:text/text()) 
let $qparts := fn:tokenize($right//cts:text/text(), ":") 
let $queryText := $qparts[last()] 
let $log := xdmp:log("$queryText : " || $queryText) 

    let $qpartsCnt := fn:count($qparts) 

    let $query := 
     if(fn:count($qparts) = 1) then 
     <root>{ 
      cts:word-query($queryText, ("case-insensitive", "wildcarded", "punctuation-insensitive", "whitespace-insensitive")) 
      }</root>/* 
     else 
     <root>{ 
      let $qparts := fn:tokenize($qparts[1],"\.") 
      let $endPart := $qparts[last()] 
      (: remove the last part in sequence as we need to create word query with it :) 
      let $qparts := fn:remove($qparts, fn:count($qparts)) 
      let $queryExp := 
      if(fn:count($qparts) = 0) then (: checks if it is nested... :) 
       cts:json-property-scope-query($endPart, cts:word-query($queryText, ("case-insensitive", "wildcarded", "punctuation-insensitive", "whitespace-insensitive"))) 
      else 
       let $xy := cts:json-property-scope-query($endPart, cts:word-query($queryText, ("case-insensitive", "wildcarded", "punctuation-insensitive", "whitespace-insensitive"))) 
       return gbrsso:buildQuery($xy, $qparts) 

      return $queryExp 
     }</root>/* 

    return $query 

};

截至今天指出，討論列表，它應該如果所包含的約束之前，前綴的容器中工作，如在：

let $search := "concept.registrar:username:WHITEMK" 

作爲一個腳註，當你嘗試要理解查詢文本如何被解析，有時候首先使用search：parse（）更容易。

很好，你找到了一個短期的解決方法。我希望這有助於長期解決方案。
