  == Overview ==
- The Surround query parser plugin  provides support within Solr for the Surround query language. See chapter 9 of [[http://manning.com/lucene/|Lucene In Action (2nd ed)]]. The query parser enables the use of span queries within  Solr.

+ 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.

  == Query Syntax ==
  Surround defines two operators. '''n''' creates an unordered SpanNearQuery and '''w''' creates an ordered one. Each of these can be prepended by an integer in the range 2-99, which indicates the maximum acceptable span distance. Without the integer, the distance defaults to 1.

  There is no room for default operator in surround query parser. For example, the query '''dog cat''' throws ParseException.
  
- Highlighting does not work with surround query parser. See the [[https://issues.apache.org/jira/browse/SOLR-3060|JIRA issue]] 
+ Highlighting support for the surround query parser was fixed in [[Solr4.2]] (see the [[https://issues.apache.org/jira/browse/SOLR-3060|SOLR-3060]])
