The most important method is parse(const String&)
.
The syntax for query strings is as follows: A Query is a series of clauses. A clause may be prefixed by:
A clause may be either:
Thus, in BNF, the query grammar is:
Query ::= ( Clause )* Clause ::= ["+", "-"] [ ":"] ( | "(" Query ")" )
Examples of appropriately formatted queries can be found in the query syntax documentation.
In TermRangeQuery
s, QueryParser tries to detect date values, eg. 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 the locale
.
By default a date is converted into a search term using the deprecated DateField
for compatibility reasons. To use the new DateTools
to convert dates, a Resolution
has to be set.
The date resolution that shall be used for RangeQueries can be set using setDateResolution(Resolution)
or setDateResolution(const String&, 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 use neither DateField
nor DateTools
in your index, you can create your own query parser that inherits QueryParser and overwrites getRangeQuery(const String&, const String&,
const String&, bool)
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.
NOTE: You must specify the required Version
compatibility when creating QueryParser:
setEnablePositionIncrements
is true by default.
