How do you apply this filter? I cant find any samples online!

First: this kind of question is better to ask on https://discuss.elastic.co/.

Second, you apply it by making a custom analyzer and specifying the trim filter in the list of filters.

Possibly..

But I always find it strange on any github issue (no matter what project), there is an enhancement or fix closed without conveying to the end user how it works!

@shavo007 When you create a new issue, the issue template says:

GitHub is reserved for bug reports and feature requests. The best place to ask a general question is at the Elastic Discourse forums at https://discuss.elastic.co.

Every repository manages these things individually, this is how we manage ours (for example, Apache projects usually use an Apache-hosted Jira and user mailing lists, Apple Swift uses Jira and mailing lists too, and has issues locked on their repository). The community at our Discourse forum is very helpful, and you'll even see a lot of the same people there that you see here.

I understand that.

But based on my search term i came here!
