# CAT segments
|
|
**Introduced 1.0**
|
|
{: .label .label-purple }
|
|
|
|
The cat segments operation lists Lucene segment-level information for each index.
|
|
|
|
## Example
|
|
|
|
```
|
|
GET _cat/segments?v
|
|
```
|
|
{% include copy-curl.html %}
|
|
|
|
To see only the information about segments of a specific index, add the index name after your query.
|
|
|
|
```
|
|
GET _cat/segments/<index>?v
|
|
```
|
|
{% include copy-curl.html %}
|
|
|
|
If you want to get information for more than one index, separate the indexes with commas:
|
|
|
|
```
|
|
GET _cat/segments/index1,index2,index3
|
|
```
|
|
{% include copy-curl.html %}
|
|
|
|
## Path and HTTP methods
|
|
|
|
```
|
|
GET _cat/segments
|
|
```
|
|
|
