/**
* This class is generated by JavaCC. The most important method is
* {@link #parse(String)}.
*
* The syntax for query strings is as follows:
* A Query is a series of clauses.
* A clause may be prefixed by:
*
* - a plus (
+) or a minus (-) sign, indicating
* that the clause is required or prohibited respectively; or
* - a term followed by a colon, indicating the field to be searched.
* This enables one to construct queries which search multiple fields.
*
*
* A clause may be either:
*
* - a term, indicating all the documents that contain this term; or
*
- a nested query, enclosed in parentheses. Note that this may be used
* with a
+/- prefix to require any of a set of
* terms.
*
*
* Thus, in BNF, the query grammar is:
*
* Query ::= ( Clause )*
* Clause ::= ["+", "-"] [<TERM> ":"] ( <TERM> | "(" Query ")" )
*
*
*
* Examples of appropriately formatted queries can be found in the query syntax
* documentation.
*
*
*
* In {@link TermRangeQuery}s, QueryParser tries to detect date values, e.g.
* date:[6/1/2005 TO 6/4/2005] produces a range query that searches
* for "date" fields between 2005-06-01 and 2005-06-04. Note that the format
* of the accepted input depends on {@link #setLocale(Locale) the locale}.
* A {@link org.apache.lucene.document.DateTools.Resolution} has to be set,
* if you want to use {@link DateTools} for date conversion.
*
*
* The date resolution that shall be used for RangeQueries can be set
* using {@link #setDateResolution(DateTools.Resolution)}
* or {@link #setDateResolution(String, DateTools.Resolution)}. The former
* sets the default date resolution for all fields, whereas the latter can
* be used to set field specific date resolutions. Field specific date
* resolutions take, if set, precedence over the default date resolution.
*
*
* If you don't use {@link DateTools} in your index, you can create your own
* query parser that inherits QueryParser and overwrites
* {@link #getRangeQuery(String, String, String, boolean, boolean)} to
* use a different method for date conversion.
*
*
* Note that QueryParser is not thread-safe.
*
* NOTE: there is a new QueryParser in contrib, which matches
* the same syntax as this class, but is more modular,
* enabling substantial customization to how a query is created.
