Marklogic JSON文档字段索引

Question

I have a ML database with all json documents.. I am having an issue with field creation for this documents.. Say I have a document

{
    "id": "1452016",
    "name": "ALEXA488",
    "identifyingInfo": {
        "preparation": {
            "chemicalConjugations": [{
                "name": "ALEXA 488"
            }]
        }
    }
}

I created a field for top level json element name ..

{
 "field-name": "concept_name",
 "field-path": [
  {
    "path": "/name",
    "weight": 1
  }
  ],
  "word-lexicon" :["http://marklogic.com/collation/en/S1"]
}

I created a field range index as well on this field..

Now when I do the search like this

xquery version "1.0-ml";
import module namespace search = "http://marklogic.com/appservices/search" at "/MarkLogic/appservices/search/search.xqy";


let $search := ' (concept_name:(*ALEXA*))'

let $options :=
   <options xmlns="http://marklogic.com/appservices/search">
    <constraint name="collection">
        <collection prefix=""/>
    </constraint>
    <constraint name="concept_name">
        <word>
            <field name="concept_name" collation="http://marklogic.com/collation/en/S1"/>
        </word>
    </constraint>
    <term>
        <term-option>case-insensitive</term-option>
        <term-option>punctuation-insensitive</term-option>
        <term-option>whitespace-insensitive</term-option>
        <term-option>wildcarded</term-option>
    </term>
    <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>format-json</search-option>
    <search-option>score-simple</search-option>
</options>

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

 let $result := search:search($search, $options, $start, $page-length)  

return $result

The search is matching the top level name and also identifyingInfo/preparation/chemicalConjugations/name ..

What should be the field path, so that it only matches the top level json element, in this case name ?

Answer 1

Your field path looks fine. You can check that with

cts:field-value-match("concept_name", "*")

But you're trying to use wildcards. Did you enable "trailing wildcard searches" on your field? Do you also want "one/two/three character searches" enabled?

Answer 2

I got this to work. Replace your constraint with:

<constraint name="concept_name">
  <value>
    <field name="concept_name" />
  </value>
</constraint>

In your field, turn on field value searches and trailing wildcard searches .

I created three docs in a database; one just like your sample, one that had "ALEXA" only in /name, and one that had "ALEXA" only in the other name. My test correctly found the two documents.
