I am trying to validate a field against a regular expression (regex). but its not validating.
I have a filed like presentation number ( which is text field) and I would like to filter this filed only that starts with 0-9 or start with +449 and +4470 using regex (^[0-9]|^+44(9|70)) .
I tried enclosing my regex in / and " but didnt work.

@sravan welcome to the community!
Are you using the Filter UI in the search bar, a filter in a visualization or a filter in a console query? It will be easier to help you if we know where you're getting stuck.
Elasticsearch does support [regular expression queries](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-regexp-query.html) and will return the docs that match. Here's a link to the regular expression syntax docs: [https://www.elastic.co/guide/en/elasticsearch/reference/current/regexp-syntax.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/regexp-syntax.html).
If you're trying to use a regex in the Search Bar filters UI, you'll need to use the [query DSL option](https://www.elastic.co/guide/en/kibana/current/field-filter.html#filter-edit).
