Django：搜索Postgresql JSON字段对象数组非特定索引查找

如何解决Django：搜索Postgresql JSON字段对象数组非特定索引查找

我将以下json附加到models.JSONField

"descriptions": [
    {
      "description": "The Chandra Source Catalog (CSC) is a general purpose virtual X-ray astrophysics facility that provides access to a carefully selected set of generally useful quantities for individual X-ray sources,and is designed to satisfy the needs of a broad-based group of scientists,including those who may be less familiar with astronomical data analysis in the X-ray regime. The first release of the CSC includes information about 94,676 distinct X-ray sources detected in a subset of public Advanced CCD Imaging Spectrometer imaging observations from roughly the first eight years of the Chandra mission. This release of the catalog includes point and compact sources with observed spatial extents ≲30''.","descriptionType": "Abstract","lang": "en-US"
    },{
      "description": "The catalog includes real X-ray sources detected with flux estimates that are at least 3 times their estimated 1σ uncertainties in at least one energy band,while maintaining the number of spurious sources at a level of ≲1 false source per field for a 100 ks observation. For each detected source,the CSC provides commonly tabulated quantities,including source position,extent,multi-band fluxes,hardness ratios,and variability statistics,derived from the observations in which the source is detected. In addition to these traditional catalog elements,for each X-ray source the CSC includes an extensive set of file-based data products that can be manipulated interactively,including source images,event lists,light curves,and spectra from each observation in which a source is detected.","descriptionType": "TechnicalInfo",{
      "description": "The catalog (1) provides access to the best estimates of the X-ray source properties for detected sources,with good scientific fidelity,and directly supports scientific analysis using the individual source data; (2) facilitates analysis of a wide range of statistical properties for classes of X-ray sources; and (3) provides efficient access to calibrated observational data and ancillary data products for individual X-ray sources,so that users can perform detailed further analysis using existing tools.","descriptionType": "Other","lang": "en-US"
    }
],

此字段可通过以下双下划线__ Django ORM属性表示法进行访问：

datasetmetarecord__json__descriptions

本质上，instance.datasetmetarecord.json是我要定位的字段。

我正在尝试执行以下queryset搜索查询：

queryset = queryset.filter(
   Q(name__unaccent__lower__icontains=search) |
   Q(name__unaccent__lower__startswith=search) |
   Q(name__unaccent__lower__trigram_similar=search) |
   Q(datasetmetarecord__json__descriptions__description=search)
)

不幸的是，Q(datasetmetarecord__json__descriptions__description=search)不适用于我所知道的搜索变量描述中的任何文本字符串...

有人会知道用于执行此查找的正确代码吗？

编辑：

这有效：

queryset = queryset.filter(
   Q(name__unaccent__lower__icontains=search) |
   Q(name__unaccent__lower__startswith=search) |
   Q(name__unaccent__lower__trigram_similar=search) |
   Q(datasetmetarecord__json__descriptions__0__description__icontains=search) |
   Q(datasetmetarecord__json__descriptions__1__description__icontains=search) |
   Q(datasetmetarecord__json__descriptions__2__description__icontains=search) 
)
