Description

This adds support for the "wildcard" field type that supports efficient execution of wildcard, prefix, and regexp queries by matching first against trigrams (or bigrams or individual characters), then post-filtering by evaluating the original field value against the pattern.

Incidentally, I think I can improve the situation for regex queries by applying the logic described in https://swtch.com/~rsc/regexp/regexp4.html

The backport to 2.x failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Navigate to the root of your repository
cd $(git rev-parse --show-toplevel)
# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/OpenSearch/backport-2.x 2.x
# Navigate to the new working tree
pushd ../.worktrees/OpenSearch/backport-2.x
# Create a new branch
git switch --create backport/backport-13461-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 b71e547e938876c2cec9fcc0328ffbd6b4a50db6
# Push it to GitHub
git push --set-upstream origin backport/backport-13461-to-2.x
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/OpenSearch/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport/backport-13461-to-2.x.
