PrecedenceQueryParser

class PrecedenceQueryParser : StandardQueryParser

This query parser works exactly as the standard query parser (StandardQueryParser), except that it respect the boolean precedence, so is parsed to <(+a +b) (+c +d)> instead of <+a +b +c +d>.

EXPERT: This class extends [StandardQueryParser], but uses [PrecedenceQueryNodeProcessorPipeline] instead of [StandardQueryNodeProcessorPipeline] to process the query tree.

var dateResolutionMap: Map<CharSequence, DateTools.Resolution>?

Returns the field to DateTools.Resolution map used to normalize each date field.

defaultOperator

var defaultOperator: StandardQueryConfigHandler.Operator

Gets implicit operator setting, which will be either Operator.AND or Operator.OR.

enablePositionIncrements

open override var enablePositionIncrements: Boolean

Set to true to enable position increments in result query.

fieldsBoost

var fieldsBoost: Map<String, Float>?

Sets the boost used for each field.

fuzzyMinSim

open override var fuzzyMinSim: Float

Get the minimal similarity for fuzzy queries.

fuzzyPrefixLength

open override var fuzzyPrefixLength: Int

Set the prefix length for fuzzy queries. Default is 0.

locale

open override var locale: Locale

Set locale used by date range parsing.

multiFields

var multiFields: Array<CharSequence>?

Set the fields a query should be expanded to when the field is null

multiTermRewriteMethod

open override var multiTermRewriteMethod: MultiTermQuery.RewriteMethod

phraseSlop

open override var phraseSlop: Int

Sets the default slop for phrases. If zero, then exact phrase matches are required. Default value is zero.

pointsConfigMap

var pointsConfigMap: Map<String, PointsConfig>?

queryBuilder

var queryBuilder: QueryBuilder

Returns the query builder used to build a object from the query node tree. The object produced by this builder is returned by parse.

queryConfigHandler

var queryConfigHandler: QueryConfigHandler?

Returns the query configuration handler, which is used during the query node tree processing. It can be null.

queryNodeProcessor

var queryNodeProcessor: QueryNodeProcessor?

Returns the processor object used to process the query node tree, it returns null if no processor is used.

syntaxParser

var syntaxParser: SyntaxParser

Returns the text parser used to build a query node tree from a query string. The default text parser instance returned by this method is a SyntaxParser.

timeZone

open override var timeZone: TimeZone

Functions

parse

open override fun parse(query: String, defaultField: String?): Query

Overrides QueryParserHelper.parse so it casts the return object to Query. For more reference about this method, check QueryParserHelper.parse.
