Hi Elastic don't save index and it save something like UUID as follow : [root@es-data-01 ~]# curl -XGET '172.24.69.16:9200/\_cat/indices' green open finallog-2017.05.07 -i5\_HbE9Twa\_-OS17yLW0w 5 1 1 0 10.9kb 5.4kb green open test4-2017.05.10 6wumml3kS5eJUTG2QFUzUw 5 1 138 0 613.3kb 306.6kb green open test4-2017.05.09 hiIbmYp0SNChAC5\_QZzFyA 5 1 41531 0 9.3mb 4.6mb green open test4-2017.05.12 B\_AmJVWUSPOFdHE2LhQu0g 5 1 138 0 619.9kb 310.3kb green open test2-2017.05.09 yhe5dKawTaGWJiqOm8dOQw 5 1 3 0 30.1kb 15kb green open test4-2017.05.13 F29DhDCbQa6s43-Guo6sYQ 5 1 138 0 484.9kb 246.3kb green open .kibana W9eLFC76Q86B0F6WFLOqNA 1 1 2 0 19.7kb 9.8kb green open test4-2017.05.14 w76gvtX6S4mtauVy6yNMMg 5 1 5466 0 1.9mb 974.4kb green open test4-2017.05.15 ivlrQiLoSB-qLd7yEYMEgQ 5 1 34 0 380.5kb 190.2kb green open test3-2017.05.09 9VRgWUxtRv-S3xICyKWP6A 5 1 1 0 10.9kb 5.4kb green open test1-2017.05.09 rKo3ZBX\_QyGaw5w7z9eGJw 5 1 1 0 10.9kb 5.4kb green open test4-2017.05.11 NCZ7xQc7T-yMSd2CQn0-Jg 5 1 138 0 485.2kb 234.6kb [root@es-data-01 ~]# ll /var/lib/elasticsearch/nodes/0/indices/ total 0 drwxr-xr-x. 7 elasticsearch elasticsearch 51 May 14 06:18 6wumml3kS5eJUTG2QFUzUw drwxr-xr-x. 6 elasticsearch elasticsearch 43 May 14 06:18 9VRgWUxtRv-S3xICyKWP6A drwxr-xr-x. 6 elasticsearch elasticsearch 43 May 14 06:18 B\_AmJVWUSPOFdHE2LhQu0g drwxr-xr-x. 7 elasticsearch elasticsearch 51 May 14 06:18 F29DhDCbQa6s43-Guo6sYQ drwxr-xr-x. 6 elasticsearch elasticsearch 43 May 14 06:18 hiIbmYp0SNChAC5\_QZzFyA drwxr-xr-x. 6 elasticsearch elasticsearch 43 May 14 06:18 -i5\_HbE9Twa\_-OS17yLW0w drwxr-xr-x. 6 elasticsearch elasticsearch 43 May 14 20:01 ivlrQiLoSB-qLd7yEYMEgQ drwxr-xr-x. 6 elasticsearch elasticsearch 43 May 14 06:18 NCZ7xQc7T-yMSd2CQn0-Jg drwxr-xr-x. 6 elasticsearch elasticsearch 43 May 14 06:18 rKo3ZBX\_QyGaw5w7z9eGJw drwxr-xr-x. 6 elasticsearch elasticsearch 43 May 14 06:18 w76gvtX6S4mtauVy6yNMMg drwxr-xr-x. 4 elasticsearch elasticsearch 27 May 14 06:22 W9eLFC76Q86B0F6WFLOqNA drwxr-xr-x. 7 elasticsearch elasticsearch 51 May 14 06:18 yhe5dKawTaGWJiqOm8dOQw ---

Yes. And what is the problem? You are not supposed to go in the directories but just use the APIs. ---

> i want to find indices with the index name What for? That said, run a `GET _cat/indices` call and you can see what is the UUID of your index. ---

Dear dadoonet why UUID ? I indexed my log with logstash, why it save it with UUID ? ---

Why not? My question is still valid. Why do you care about that? ---

because i want to search by my name instead of UUID ---

Then run: ```auto GET yourindexname/_search ``` And you will search within your index name. ---

Elasticsearch used to use the index name in the data directory structure, but as there were index names that were valid but caused problems with various file systems, the index name was replaced by UUID in the file system path to avoid having to restrict index naming further. Through all APIs you use the index name, not the UUID, so it should be transparent to you. ---
