How to perform multiple condition searches on ES indexes using curl commands

To perform multiple condition searches on Elasticsearch indices using curl commands, follow these steps:

Construct the JSON Query: Use the bool query in JSON to combine multiple search conditions.
Execute the Curl Command: Send the JSON query to the appropriate Elasticsearch endpoint with curl.

Example:

curl -X GET “http://localhost:9200/your_index/_search” \
-H ‘Content-Type: application/json’ \
-d ‘{“query”: {“bool”: {
    “must”: [
        { “term”: { “field1”: “value1” } },
        { “range”: { “age”: { “gte”: 18, “lte”: 25 } } }
    ],
    “filter”: [
        { “exists”: { “field”: “status” } }
    ]
}}}’

curl –X GET “http://localhost:9200/your_index/_search” \

–H ‘Content-Type: application/json’ \

–d ‘{“query”: {“bool”: {

“must”: [

{ “term”: { “field1”: “value1” } },

{ “range”: { “age”: { “gte”: 18, “lte”: 25 } } }

“filter”: [

{ “exists”: { “field”: “status” } }

]

}}}’

Explanation:

bool query: Combines multiple conditions using must, must_not, and filter.
Must Clauses: Conditions that must be satisfied for a document to match.
Filter Clauses: Conditions that narrow results without affecting scoring.
curl Command: Sends the JSON query to Elasticsearch.

This approach allows you to perform complex searches across multiple fields in your ES index.
