- 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:
- [source,console]
- --------------------------------------------------
- GET /_search
- {
- "query": {
- "span_multi": {
- "match": {
- "prefix": { "user": { "value": "ki" } }
- }
- }
- }
- }
- --------------------------------------------------
- A boost can also be associated with the query:
- [source,console]
- --------------------------------------------------
- GET /_search
- {
- "query": {
- "span_multi": {
- "match": {
- "prefix": { "user": { "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
- boolean query limit (defaults to 1024).To avoid an unbounded expansion you can set the <<query-dsl-multi-term-rewrite,
- 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,`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.
