indices.query.bool.max_clause_count is set automatically and does
not default to 4096 as before. This remove mentions of 4096
from query documentations.
Relates to PR#91811
In the upcoming Lucene 9 release, `indices.query.bool.max_clause_count` is
going to apply to the entire query tree rather than per `bool` query. In order
to avoid breaks, the limit has been bumped from 1024 to 4096.
The semantics will effectively change when we upgrade to Lucene 9, this PR
is only about agreeing on a migration strategy and documenting this change.
To avoid further breaks, I am leaning towards keeping the current setting name
even though it contains `bool`. I believe that it still makes sense given that
`bool` queries are typically the main contributors to high numbers of clauses.

This commit moves the documentation and examples for the `index_prefixes`
option on text fields to its own file, to bring it in line with other mapping
parameters, and expands a bit on both.
By default span_multi query will limit term expansions = boolean max clause.
This will limit high heap usage in case of high cardinality term
expansions. This applies only if top_terms_N is not used in inner multi
query.
* Fix index prefixes to work with span_multi
Text fields that use `index_prefixes` can rewrite `prefix` queries into
`term` queries internally. This commit fix the handling of this rewriting
in the `span_multi` query.
This change also copies the index options of the text field into the
prefix field in order to be able to run positional queries. This is mandatory
for `span_multi` to work but this could also be useful to optimize `match_phrase_prefix`
queries in a follow up. Note that this change can only be done on indices created
after 6.3 since we set the index options to doc only in this version.
Fixes#31056
This commit makes queries and filters parsed the same way using the
QueryParser abstraction. This allowed to remove duplicate code that we had
for similar queries/filters such as `range`, `prefix` or `term`.
