elasticsearchHow do I use an elasticsearch filter?
An Elasticsearch filter is a query that is used to limit the search results within a specific index or type. It can be used to filter out documents that do not match a certain criteria.
For example, the following code block can be used to filter out documents with a field called "status" that is not equal to "published":
GET /my_index/_search
{
"query": {
"bool": {
"filter": {
"term": {
"status": "published"
}
}
}
}
}
The code block consists of the following parts:
-
GET /my_index/_search
: This is the request URL which specifies the index to search. -
query
: This is the query object which contains the filter. -
bool
: This is the boolean query which allows for combining multiple queries. -
filter
: This is the filter object which contains the criteria for filtering the documents. -
term
: This is the term query which is used to match the specific field of the document. -
status
: This is the field name which is used to filter the documents. -
published
: This is the value which is used to filter out the documents that do not match the criteria.
For more information on using Elasticsearch filters, see the Elasticsearch documentation.
