C# Class Rubber.DSL.Query.QueryStringQueryBuilder

A query that parses a query string and runs it. There are two modes that this operates. The first, when no field is added (using {@link #field(string)}, will run the query once and non prefixed fields will use the {@link #defaultField(string)} set. The second, when one or more fields are added (using {@link #field(string)}), will run the parsed query against the provided fields, and combine them either using DisMax or a plain boolean query (see {@link #useDisMax(boolean)}).

Public Methods

Method	Description
AllowLeadingWildcard ( bool allowLeadingWildcard ) : QueryStringQueryBuilder	Should leading wildcards be allowed or not. Defaults to `true`.
AnalyzeWildcard ( bool analyzeWildcard ) : QueryStringQueryBuilder	Set to `true` to enable analysis on wildcard and prefix queries.
Analyzer ( string analyzer ) : QueryStringQueryBuilder	The optional analyzer used to analyze the query string. Note, if a field has search analyzer defined for it, then it will be used automatically. Defaults to the smart search analyzer.
AutoGeneratePhraseQueries ( bool autoGeneratePhraseQueries ) : QueryStringQueryBuilder	Set to true if phrase queries will be automatically generated when the analyzer returns more than one term from whitespace delimited text. NOTE: this behavior may not be suitable for all languages. Set to false if phrase queries should only be generated when surrounded by double quotes.
Boost ( float boost ) : QueryStringQueryBuilder	Sets the boost for this query. Documents matching this query will (in addition to the normal weightings) have their score multiplied by the boost provided.
DefaultField ( string defaultField ) : QueryStringQueryBuilder	The default field to run against when no prefix field is specified. Only relevant when not explicitly adding fields the query string will run against.
DefaultOperator ( Operator defaultOperator ) : QueryStringQueryBuilder	Sets the boolean operator of the query parser used to parse the query string. In default mode ({@link FieldQueryBuilder.Operator#OR}) terms without any modifiers are considered optional: for example `capital of Hungary` is equal to `capital OR of OR Hungary`. In {@link FieldQueryBuilder.Operator#AND} mode terms are considered to be in conjunction: the above mentioned query is parsed as `capital AND of AND Hungary`
EnablePositionIncrements ( bool enablePositionIncrements ) : QueryStringQueryBuilder	Set to `true` to enable position increments in result query. Defaults to `true`. When set, result phrase and multi-phrase queries will be aware of position increments. Useful when e.g. a StopFilter increases the position increment of the token that follows an omitted token.
Field ( string field ) : QueryStringQueryBuilder	Adds a field to run the query string against.
Field ( string field, float boost ) : QueryStringQueryBuilder	Adds a field to run the query string against with a specific boost.
FuzzyMinSim ( float fuzzyMinSim ) : QueryStringQueryBuilder	Set the minimum similarity for fuzzy queries. Default is 0.5f.
FuzzyPrefixLength ( int fuzzyPrefixLength ) : QueryStringQueryBuilder	Set the minimum similarity for fuzzy queries. Default is 0.5f.
LowercaseExpandedTerms ( bool lowercaseExpandedTerms ) : QueryStringQueryBuilder	Whether terms of wildcard, prefix, fuzzy and range queries are to be automatically lower-cased or not. Default is `true`.
MinimumShouldMatch ( string minimumShouldMatch ) : QueryStringQueryBuilder
PhraseSlop ( int phraseSlop ) : QueryStringQueryBuilder	Sets the default slop for phrases. If zero, then exact phrase matches are required. Default value is zero.
QueryStringQueryBuilder ( string querystring ) : System
Rewrite ( string rewrite ) : QueryStringQueryBuilder
TieBreaker ( float tieBreaker ) : QueryStringQueryBuilder	When more than one field is used with the query string, and combined queries are using dis max, control the tie breaker for it.
ToJsonObject ( ) : object
ToString ( ) : string
UseDisMax ( bool useDisMax ) : QueryStringQueryBuilder	When more than one field is used with the query string, should queries be combined using dis max, or boolean query. Defaults to dis max (`true`).
