=== Search Settings
|
|
|
|
The following _expert_ setting can be set to manage global search limits.
|
|
|
|
[[indices-query-bool-max-clause-count]]
|
|
`indices.query.bool.max_clause_count`::
|
|
Defaults to `1024`.
|
|
|
|
This setting limits the number of clauses a Lucene BooleanQuery can have. The
|
|
default of 1024 is quite high and should normally be sufficient. This limit does
|
|
not only affect Elasticsearchs `bool` query, but many other queries are rewritten to Lucene's
|
|
BooleanQuery internally. The limit is in place to prevent searches from becoming to large
|
|
and taking up too much CPU and memory. In case you consider to increase this setting,
|
|
make sure you exhausted all other options to avoid having to do this. Higher values can lead
|
|
to performance degradations and memory issues, especially in clusters with a high load or
|
|
few resources.
