Sample query: querying a metadata field of a topic
To query metadata fields, use the period "." as a field/subfield separator, rather than the number sign "#" used in the OpenSearch index.
The OpenSearch index stores metadata fields using a number sign, "#". For example, here's a fragment of an OpenSearch index:
"_source": {
"clientId": "ish_4489824-4452831-16",
"dynamicDate": {
"FTESTDATE#logical#value": "2023-01-31T14:44:00+0000",
"FTESTDATEMV#logical#value": [
"2023-01-15T15:45:00Z",
"2023-01-10T15:45:00Z"
]
},
"dynamicDouble": {
"FTESTNUMBER#logical#value": 123.56,
"FTESTNUMBERMV#logical#value": [
11.11,
22.22
]
},
"dynamicText": {
"FTESTSTRING#logical#value": "Single string",
"FTESTSTRINGMV#logical#value": [
"First string",
"Second string"
]
},
However, you should replace the number sign "#" with a period "." when querying these fields through GraphQL. For example, here's a sample query showing a metadata field being queried:
{
search(criteria: {metadataField: {keys: ["FTESTSTRING.logical.value"], value: "Example"} }) {
results {
hits
edges {
node {
broker {
title
}
search {
fields
id
rawContent
mainContentField
}
}
}
}
}
}
