Wildcard Query
editWildcard Query
editMatches documents that have fields matching a wildcard expression (not
analyzed). Supported wildcards are *
, which matches any character
sequence (including the empty one), and ?
, which matches any single
character. Note that this query can be slow, as it needs to iterate over many
terms. In order to prevent extremely slow wildcard queries, a wildcard
term should not start with one of the wildcards *
or ?
. The wildcard
query maps to Lucene WildcardQuery
.
{ "wildcard" : { "user" : "ki*y" } }
A boost can also be associated with the query:
{ "wildcard" : { "user" : { "value" : "ki*y", "boost" : 2.0 } } }
Or :
{ "wildcard" : { "user" : { "wildcard" : "ki*y", "boost" : 2.0 } } }
This multi term query allows to control how it gets rewritten using the rewrite parameter.
