How can I filter results in Elasticsearch?

You can filter results in Elasticsearch using the filter context in your query. This allows you to specify conditions that documents must meet to be included in the results.

Can you give me an example of a filter query?

Sure! Here's a simple example:

{
  "query": {
    "bool": {
      "filter": [
        { "term": { "status": "active" } },
        { "range": { "age": { "gte": 30 } }}
      ]
    }
  }
}

This query filters for documents where the status is 'active' and age is greater than or equal to 30.

What types of filters can I use?

You can use various types of filters such as term filters, range filters, exists filters, and more. Each serves different purposes depending on your data.

Are filters case-sensitive?

Yes, filters in Elasticsearch are case-sensitive by default. You need to ensure that the case matches the indexed data.
