[Hossein_Bagherzadega (Hossein Bagherzadegan Talkhouncheh)]

i need to search and index inside an inline script but could not find any docs or sample for it is the any chance that inline script support search on index something like this

query": {
    "bool": {
      "must_not": {
        "script": {
          "script": {
            "source": """
              def restrictionType = params.restriction.type;
              def customerBusinessUnitUuid = params.restriction.customerBusinessUnitUuid;
              def searchResult = ctx._index("product_restriction_index").search(,'{"bool": {"must": [{ "match": { "type": restrictionType } },{ "match": { "customer_business_unit_uuid": customerBusinessUnitUuid } }]}}');
              def restrictionUuids = searchResult.hits.hits.collect(hit -> hit._source['productUuid.keyword'].value);
              def currentDirectSku = doc['directSku.keyword'].value;
              def isInRestrictionUuids = restrictionUuids.contains(currentDirectSku);
              (restrictionType == 'whitelist' && !isInRestrictionUuids) || (restrictionType == 'blacklist' && isInRestrictionUuids);
            """,
            "lang": "painless",
            "params": {
              "restriction": { 
                "type": "whitelist", 
                "customerBusinessUnitUuid": "4a415944-76f5-41c8-b229-48b52be619f5" 
              }
            }
          }
        }
      }
