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.

dateResolution

open override var dateResolution: DateTools.Resolution

Sets the default Resolution used for certain field when no Resolution is defined for this field.

defaultOperator

var enableGraphQueries: Boolean

enablePositionIncrements

var enablePositionIncrements: Boolean

Set to true to enable position increments in result query.

field

lateinit var field: String

fieldToDateResolution

fuzzyMinSim

open override var fuzzyMinSim: Float

Set the minimum similarity for fuzzy queries. Default is 2f.

fuzzyPrefixLength

open override var fuzzyPrefixLength: Int

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

locale

open override var locale: Locale

Returns current locale, allowing access by subclasses.

multiTermRewriteMethod

operator

var operator: QueryParser.Operator

The actual operator that parser uses to combine query terms

phraseSlop

Functions

createBooleanQuery

fun createBooleanQuery(field: String, queryText: String, operator: BooleanClause.Occur): Query?

createMinShouldMatchQuery

fun createMinShouldMatchQuery(field: String, queryText: String, fraction: Float): Query?

createPhraseQuery

fun createPhraseQuery(field: String, queryText: String, phraseSlop: Int): Query?

discardEscapeChar

fun discardEscapeChar(input: String): String

Returns a String where the escape char has been removed, or kept only once if there was a double escape.

getDateResolution

fun getDateResolution(fieldName: String): DateTools.Resolution?

Returns the date resolution that is used by RangeQueries for the given field. Returns null, if no default or field specific date resolution has been set for the given field.

handleBareFuzzy

open fun handleBareFuzzy(qfield: String, fuzzySlop: Token, termImage: String): Query

handleBareTokenQuery

fun handleBareTokenQuery(qfield: String, term: Token, fuzzySlop: Token?, prefix: Boolean, wildcard: Boolean, fuzzy: Boolean, regexp: Boolean): Query?

handleBoost

fun handleBoost(q: Query?, boost: Token?): Query?

handleQuotedTerm

fun handleQuotedTerm(qfield: String, term: Token, fuzzySlop: Token?): Query?

init

fun init(f: String, a: Analyzer)

Initializes a query parser. Called by the QueryParser constructor

parse

open fun parse(query: String): Query?

Parses a query string, returning a Query.

ReInit

abstract fun ReInit(stream: CharStream)

setDateResolution

fun setDateResolution(fieldName: String, dateResolution: DateTools.Resolution)

Sets the date resolution used by RangeQueries for a specific field.

setDefaultOperator

fun setDefaultOperator(op: QueryParser.Operator)

Sets the boolean operator of the QueryParser. In default mode (OR_OPERATOR) terms without any modifiers are considered optional: for example capital of Hungary is equal to capital OR of OR Hungary.

In AND_OPERATOR mode terms are considered to be in conjunction: the above-mentioned query is parsed as capital AND of AND Hungary
