## Class QueryParser

- java.lang.Object
- - org.apache.lucene.queryparser.surround.parser.QueryParser

- All Implemented Interfaces:
    QueryParserConstants

      public class QueryParser
      extends Object
      implements QueryParserConstants

  This class is generated by JavaCC. The only method that clients should need to call is `parse()`.

  This parser generates queries that make use of position information (Span queries). It provides positional operators (`w` and `n`) that accept a numeric distance, as well as boolean operators (`and`, `or`, and `not`, wildcards (`*` and `?`), quoting (with `"`), and boosting (via `^`).

  The operators (W, N, AND, OR, NOT) can be expressed lower-cased or upper-cased, and the non-unary operators (everything but NOT) support both infix `(a AND b AND c)` and prefix `AND(a, b, c)` notation.

  The W and N operators express a positional relationship among their operands. N is ordered, and W is unordered. The distance is 1 by default, meaning the operands are adjacent, or may be provided as a prefix from 2-99. So, for example, 3W(a, b) means that terms a and b must appear within three positions of each other, or in other words, up to two terms may appear between a and b.
