And Filter¶
A filter that matches documents using AND boolean operator on other queries. This filter is more performant then bool filter. Can be placed within queries that accept a filter.
{
"filtered" : {
"query" : {
"term" : { "name.first" : "shay" }
},
"filter" : {
"and" : [
{
"range" : {
"postDate" : {
"from" : "2010-03-01",
"to" : "2010-04-01"
}
}
},
{
"prefix" : { "name.second" : "ba" }
}
]
}
}
}
Caching¶
The result of the filter is not cached by default. The _cache can be set to true in order to cache it (tough usually not needed). Since the _cache element requires to be set on the and filter itself, the structure then changes a bit to have the filters provided within a filters element:
{
"filtered" : {
"query" : {
"term" : { "name.first" : "shay" }
},
"filter" : {
"and" :
"filters": [
{
"range" : {
"postDate" : {
"from" : "2010-03-01",
"to" : "2010-04-01"
}
}
},
{
"prefix" : { "name.second" : "ba" }
}
],
"_cache" : true
}
}
}
}
