A bug in Opensearch Java Client v2.x caused an issue with the enum ZeroTermsQuery
It was fixed in OpenSearch Java Client v3, just merged.
We should remove the override:
|
/** |
|
* If an internal variable is an enum represented by all upper case, the Remote client may have it mapped in lower case. This method lowercases these enum values |
|
* @param field The JSON field to lowercase the value |
|
* @param json The full JSON to process |
|
* @return The JSON with the value lowercased |
|
*/ |
|
public static String lowerCaseEnumValues(String field, String json) { |
|
if (field == null) { |
|
return json; |
|
} |
|
if (json == null) { |
|
return null; |
|
} |
|
// Use a matcher to find and replace the field value in lowercase |
|
Matcher matcher = Pattern.compile("(\"" + Pattern.quote(field) + "\"):(\"[A-Z_]+\")").matcher(json); |
|
StringBuffer sb = new StringBuffer(); |
|
while (matcher.find()) { |
|
matcher.appendReplacement(sb, matcher.group(1) + ":" + matcher.group(2).toLowerCase(Locale.ROOT)); |
|
} |
|
matcher.appendTail(sb); |
|
return sb.toString(); |
|
} |
While technically not semver compatible for 3.0 to 3.1, it is not used outside this repo so should be safe to remove:
Alternately we can leave it in the util and mark it deprecated, and remove the Remote Client usage of it.
