Public Static Fields
Public Static Methods
Escape Returns a String where those characters that QueryParser expects to be escaped are escaped by a preceding \ . Main Parse Overloaded. Parses a query string, returning a {@link Lucene.Net.search.Query}.
Public Instance Constructors
QueryParser
Overloaded. Initializes a new instance of the QueryParser class.
Public Instance Fields
Public Instance Methods
Clause Conjunction Disable_tracing Enable_tracing Equals (inherited from Object )
Determines whether the specified Object is equal to the current Object .
GenerateParseException GetAnalyzer GetDefaultOperator Gets implicit operator setting, which will be either AND_OPERATOR or OR_OPERATOR. GetField GetFuzzyMinSim Get the minimal similarity for fuzzy queries. GetFuzzyPrefixLength Get the prefix length for fuzzy queries. GetHashCode (inherited from Object )
Serves as a hash function for a particular type, suitable for use in hashing algorithms and data structures like a hash table.
GetLocale Returns current locale, allowing access by subclasses. GetLowercaseExpandedTerms GetLowercaseWildcardTerms GetNextToken GetOperator Gets implicit operator setting, which will be either DEFAULT_OPERATOR_AND or DEFAULT_OPERATOR_OR. GetPhraseSlop Gets the default slop for phrases. GetToken GetType (inherited from Object )
Gets the Type of the current instance.
Modifiers Parse Overloaded. Parses a query string, returning a {@link Lucene.Net.search.Query}. Query ReInit Overloaded. SetDefaultOperator 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 .AND_OPERATOR mode terms are considered to be in conjuction: the above mentioned query is parsed as capital AND of AND Hungary
SetFuzzyMinSim Set the minimum similarity for fuzzy queries. Default is 0.5f. SetFuzzyPrefixLength Set the prefix length for fuzzy queries. Default is 0. SetLocale Set locale used by date range parsing. SetLowercaseExpandedTerms Whether terms of wildcard, prefix, fuzzy and range queries are to be automatically lower-cased or not. Default is true . SetLowercaseWildcardTerms Whether terms of wildcard, prefix, fuzzy and range queries are to be automatically lower-cased or not. Default is true . SetOperator Sets the boolean operator of the QueryParser. In default mode (DEFAULT_OPERATOR_OR ) terms without any modifiers are considered optional: for example capital of Hungary is equal to capital OR of OR Hungary .DEFAULT_OPERATOR_AND terms are considered to be in conjuction: the above mentioned query is parsed as capital AND of AND Hungary
SetPhraseSlop Sets the default slop for phrases. If zero, then exact phrase matches are required. Default value is zero. Term ToString (inherited from Object )
Returns a String that represents the current Object .
Protected Instance Methods
Finalize (inherited from Object )
Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.
MemberwiseClone (inherited from Object )
Creates a shallow copy of the current Object .
Protected Internal Instance Methods
AddClause GetBooleanQuery Overloaded. Factory method for generating query, given a set of clauses. By default creates a boolean query composed of clauses passed in. Can be overridden by extending classes, to modify query being returned. GetFieldQuery Overloaded. Base implementation delegates to {@link #GetFieldQuery(String,String)}. This method may be overridden, for example, to return a SpanNearQuery instead of a PhraseQuery. GetFuzzyQuery Overloaded. Factory method for generating a query (similar to {@link #getWildcardQuery}). Called when parser parses an input term token that has the fuzzy suffix (~) appended. GetPrefixQuery GetRangeQuery Overloaded. GetWildcardQuery
