DQL issue in opensearch-dashbaord

Hello Team,

Currently I am facing an issue with Dashboard Query Language.

I have field called host who’s value is abc-1-something-a-one-0 , “abc-1-something-a-two-0” and “abc-1-something-a-Three-0” in Opensearch-dashboard.

When I write a query to filter abc-1-something-a-one-0 it give me the result for all three values. I am writing query as follows.


It not considering hipen (-) in the string. Is there any way to write query for the values which has special character in it.
