Indexing unstructured data

[akml_kk (Ahmed HADDAD)]

Hello,i've already indexed semi_structured data (Csv Files) to elasticsearch using logstash.
is it possible to index unstructured data to elasticsearch using logstash too ?
if yes could you bring the documentation for that cause i didn't find it
Thanks

use grok plugin to parse unstructured string to fields. for ref:

use https://grokdebug.herokuapp.com/ to write and test grok patterns.
