Prefix Filter
editPrefix Filter
editFilters documents that have fields containing terms with a specified prefix (not analyzed). Similar to prefix query, except that it acts as a filter. Can be placed within queries that accept a filter.
{
"constant_score" : {
"filter" : {
"prefix" : { "user" : "ki" }
}
}
}
Caching
editThe result of the filter is cached by default. The _cache can be set
to false in order not to cache it. Here is an example:
{
"constant_score" : {
"filter" : {
"prefix" : {
"user" : "ki",
"_cache" : false
}
}
}
}
