[[query-dsl-prefix-query]]
=== Prefix Query

Matches documents that have fields containing terms with a specified
prefix (*not analyzed*). The prefix query maps to Lucene `PrefixQuery`.
The following matches documents where the user field contains a term
that starts with `ki`:

[source,js]
--------------------------------------------------
{
    "prefix" : { "user" : "ki" }
}
--------------------------------------------------

A boost can also be associated with the query:

[source,js]
--------------------------------------------------
{
    "prefix" : { "user" :  { "value" : "ki", "boost" : 2.0 } }
}
--------------------------------------------------

Or :

[source,js]
--------------------------------------------------
{
    "prefix" : { "user" :  { "prefix" : "ki", "boost" : 2.0 } }
}
--------------------------------------------------

This multi term query allows to control how it gets rewritten using the
<<query-dsl-multi-term-rewrite,rewrite>>
parameter.
