No results in wildcard searches when missing first letter #2648

Description

@niklastha

We encountered a problem when using the raw filter with wildcard
It seems like there needs to be at least the first letter of the wanted string to get results with the substring.:

    Additional info:
    There was an error in the Exceptionless-Web-Log providing the problem with the query
    "allow_leading_wildcard" is set to false in the post request to elasticsearch
    without that, going against elasticsearch itself, the results are correct

    Thanks for the update and for tracking down the Elasticsearch setting. We’ve historically disabled leading wildcard searches, which can be expensive and affect overall system performance. We’ll discuss this further with the team before making any changes.

    I understand. Maybe a setting to enable for self hosters would be nice, if performance is the only concern
