Lucene Query String Elasticsearch “less than or equal to”[URI Search]

Question

On so many websites they teach how to query data from Elasticsearch using range query. I would like to query data that is less than or equal to a certain number from Elasticsear

You will want to use Query String Syntax (https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html) ranges combined with the URI Search (https://www.elastic.co/guide/en/elasticsearch/reference/current/search-uri-request.html)

Ranges

Ranges can be specified for date, numeric or string fields. Inclusive ranges are specified with square brackets [min TO max] and exclusive ranges with curly brackets {min TO max}.

    All days in 2012:

    date:[2012/01/01 TO 2012/12/31]

    Numbers 1..5

    count:[1 TO 5]

    Tags between alpha and omega, excluding alpha and omega:

    tag:{alpha TO omega}

    Numbers from 10 upwards

    count:[10 TO *]

    Dates before 2012

    date:{* TO 2012/01/01}

Curly and square brackets can be combined:

    Numbers from 1 up to but not including 5

    count:[1..5}

Ranges with one side unbounded can use the following syntax:

age:>10
age:>=10
age:<10
age:<=10

Note

To combine an upper and lower bound with the simplified syntax, you would need to join two clauses with an AND operator:

age:(>=10 AND < 20)
age:(+>=10 +<20)

The parsing of ranges in query strings can be complex and error prone. It is much more reliable to use an explicit range filter.

URI Search

A search request can be executed purely using a URI by providing request parameters. Not all search options are exposed when executing a search using this mode, but it can be handy for quick "curl tests". Here is an example:

$ curl -XGET
'http://localhost:9200/twitter/tweet/_search?q=user:kimchy'
