Error when searching in a specific field

Elastic Stack Elasticsearch
1

hello,

I got error "failed to connect to console's backed. please check the kibana server is up and running" when tried to search on field "file_content".
here is my query

{
			"query": {
				"multi_match": {
					"query": "specimen book",
					"fields": ["judul^3", "deskripsi", "file_content"],
					"operator": "AND",
					"type" : "bool_prefix", 
					"fuzziness": "AUTO",
					"prefix_length" : 5
				}
			},
			"sort": [
				{
					"_score": {
						"order": "desc"
					}
				}
			],
			"highlight": {
				"pre_tags": [
				  "<b>"
				],
				"post_tags": [
				  "</b>"
				],
				"fields": {
				  "file_content": {
					"number_of_fragments": 1,
					"fragment_size": 100,
					"type": "plain"
				  }
				},
				"max_analyzed_offset": 1000000
			}
		  }

When I removed "file_content" on the fields and highlight, the result is normal.

"file_content" is an index for storing the text from an extracted PDF file.

Welcome to our community! :smiley:

Please don't post pictures of text, logs or code. They are difficult to read, impossible to search and replicate (if it's code), and some people may not be even able to see them. Instead, post the code and the response so we can see it :slight_smile:

I'm sorry, I just edited it
