Rearranges the FingerprintAnalyzer so that AsciiFolding comes earlier in the chain (after lowercasing, before stop removal, for maximum deduping power)
Closes#18266
This commit fixes the Debian package requires clause for bash. For the
RPM it is okay to specify the binary, but for the Debian package the
package name must be specified.
This commit ensures that if CORS is enabled, then Origin headers are
checked regardless of whether the request came from a browser or not.
In the past, we only proceeded with CORS checks if the User-Agent was a
browser.
(same name and UUID) exists in the cluster state. This resolves a
situation where if an index data folder was copied into a node's data
directory while the node is running and that index had a tombstone in
the cluster state, the index would still get imported.

It will keep using the caching terms enum for keyword/text fields and falls back
to IndexSearcher.count for fields that do not use the inverted index for
searching (such as numbers and ip addresses). Note that this probably means that
significant terms aggregations on these fields will be less efficient than they
used to be. It should be ok under a sampler aggregation though.
This moves tests back to the state they were in before numbers started using
points, and also adds a new test that significant terms aggs fail if a field is
not indexed.
In the long term, we might want to follow the approach that Robert initially
proposed that consists in collecting all documents from the background filter in
order to compute frequencies using doc values. This would also mean that
significant terms aggregations do not require fields to be indexed anymore.
Today we encourage users to set their minimum and maximum heap settings
equal to each other to prevent the heap from resizing. Yet, the default
heap settings do not start Elasticsearch in this fashion. This commit
addresses this discrepancy by setting the default min heap to '512m' and
the default max heap to the default min heap.

This commit modifies two logging statements in the
IndexingMemoryController to log the key for the setting
indices.memory.index_buffer_size instead of the object.

* Docs: First pass at improving analyzer docs
I've rewritten the intro to analyzers plus the docs
for all analyzers to provide working examples.
I've also removed:
* analyzer aliases (see #18244)
* analyzer versions (see #18267)
* snowball analyzer (see #8690)
Next steps will be tokenizers, token filters, char filters
* Fixed two typos
This commit adds a hard requirement to the RPM and Debian packages for
/bin/bash to be present, and adds a note regarding this to the migration
docs.

I am unable to set ec2 discovery tags because this setting was
accidentally omitted from the register settings list in
Ec2DiscoveryPlugin.java. I get this:
java.lang.IllegalArgumentException: unknown setting [discovery.ec2.tag.project]
In the plugin script we set the setting default.path.conf to control the
path to the configuration file. But the default directory might not
exist in which case we can run into exceptions. This commit restores a
guard against this directory not existing.
This commit switches the command-line scripts to use bash instead of sh
so that we can take advantage of features that bash provides like
arrays.

An additional sanity check introduced by #17821 makes some tests fail. This check verifies that
only one shard with same shard id is allocated to a node. This commit fixes a bug in
ClusterStateCreationUtils which would construct a cluster state that allocated two shards with same
id to the same node.
