Class SimpleQueryStringBuilder

  • All Implemented Interfaces:
    NamedWriteable, Writeable, ToXContent, ToXContentObject, QueryBuilder, Rewriteable<QueryBuilder>
    public class SimpleQueryStringBuilder
extends AbstractQueryBuilder<SimpleQueryStringBuilder>
    SimpleQuery is a query parser that acts similar to a query_string query, but won't throw exceptions for any weird string syntax. It supports the following:
    • '+' specifies AND operation: token1+token2
    • '|' specifies OR operation: token1|token2
    • '-' negates a single token: -token0
    • '"' creates phrases of terms: "term1 term2 ..."
    • '*' at the end of terms specifies prefix query: term*
    • '(' and ')' specifies precedence: token1 + (token2 | token3)
    • '~N' at the end of terms specifies fuzzy query: term~1
    • '~N' at the end of phrases specifies near/slop query: "term1 term2"~5

    See: SimpleQueryStringQueryParser for more information.

    This query supports these options:

    Required: query - query text to be converted into other queries

    Optional: analyzer - anaylzer to be used for analyzing tokens to determine which kind of query they should be converted into, defaults to "standard" default_operator - default operator for boolean queries, defaults to OR fields - fields to search, defaults to _all if not set, allows boosting a field with ^n For more detailed explanation of the query string syntax see also the online documentation.

        Add a field to run the query against with a specific boost.

      • fields

        public SimpleQueryStringBuilder fields​(java.util.Map<java.lang.String,​java.lang.Float> fields)
        Add several fields to run the query against with a specific boost.

      • fields

        public java.util.Map<java.lang.String,​java.lang.Float> fields()
        Returns the fields including their respective boosts to run the query against.
