In a few previous PR's we restructured the ES|QL docs to make it possible to generate them dynamically. This PR just moves a few files around to make the query languages docs easier to work with, and a little more organized like the ES|QL docs. A bit part of this was setting up redirects to the new locations, so other repo's could correctly link to the elasticsearch docs.

Span multi-term query [query-dsl-span-multi-term-query]
The span_multi
query allows you to wrap a multi term query
(one of wildcard, fuzzy, prefix, range or regexp query) as a span query
, so it can be nested. Example:
GET /_search
{
"query": {
"span_multi": {
"match": {
"prefix": { "user.id": { "value": "ki" } }
}
}
}
}
A boost can also be associated with the query:
GET /_search
{
"query": {
"span_multi": {
"match": {
"prefix": { "user.id": { "value": "ki", "boost": 1.08 } }
}
}
}
}
::::{warning}
span_multi
queries will hit too many clauses failure if the number of terms that match the query exceeds the indices.query.bool.max_clause_count
search setting. To avoid an unbounded expansion you can set the rewrite method of the multi term query to top_terms_*
rewrite. Or, if you use span_multi
on prefix
query only, you can activate the index_prefixes
field option of the text
field instead. This will rewrite any prefix query on the field to a single term query that matches the indexed prefix.
