Briefly, this error occurs when OpenSearch encounters an unexpected IP range parameter during the parsing process. This could be due to incorrect syntax, an invalid IP range, or a bug in the software. To resolve this issue, you can try the following: 1) Check and correct the syntax of your IP range parameter; 2) Verify that the IP range you’re using is valid and correctly formatted; 3) Update your OpenSearch software to the latest version to fix any potential bugs.

Overview
Search refers to the searching of documents in an index or multiple indices. The simple search is just a GET API request to the _search endpoint. The search query can either be provided in query string or through a request body.
Examples
When looking for any documents in this index, if search parameters are not provided, every document is a hit and by default 10 hits will be returned.
GET my_documents/_search
A JSON object is returned in response to a search query. A 200 response code means the request was completed successfully.
{
"took" : 1,
"timed_out" : false,
"_shards" : {
"total" : 2,
"successful" : 2,
"failed" : 0
},
"hits" : {
"total" : 2,
"max_score" : 1.0,
"hits" : [
...
]
}
}Notes and good things to know
- Distributed search is challenging and every shard of the index needs to be searched for hits, and then those hits are combined into a single sorted list as a final result.
- There are two phases of search: the query phase and the fetch phase.
- In the query phase, the query is executed on each shard locally and top hits are returned to the coordinating node. The coordinating node merges the results and creates a global sorted list.
- In the fetch phase, the coordinating node brings the actual documents for those hit IDs and returns them to the requesting client.
- A coordinating node needs enough memory and CPU in order to handle the fetch phase.
Log Context
Log “Unexpected ip range parameter: [” + parser.currentName() + “]” class name is IpRangeAggregationBuilder.java. We extracted the following from OpenSearch source code for those seeking an in-depth context :
} else if (RangeAggregator.Range.TO_FIELD.match(parser.currentName(); parser.getDeprecationHandler())) {
to = parser.textOrNull();
} else if (MASK_FIELD.match(parser.currentName(); parser.getDeprecationHandler())) {
mask = parser.text();
} else {
throw new ParsingException(parser.getTokenLocation(); "Unexpected ip range parameter: [" + parser.currentName() + "]");
}
}
if (mask != null) {
if (key == null) {
key = mask;
