- 
- The default value is "`1`".
- 
- == hl.fragsize ==
- 
- The size, in characters, of fragments to consider for highlighting.  "`0`" indicates that the whole field value should be used (no fragmenting). This parameter accepts per-field overrides.

  = Response =
  
  By default, the response from the Standard Query Handler contains one `<result>` block, which is un unnamed.  If the `debugQuery` parameter is used, then an additional `<lst>` block will be returned, using the name "debug".  This will contain some useful debugging info, including the original query string, the parsed query string, and explain info for each document in the `<result>` block.  If the `explainOther` parameter is also used, then additional explain info will be provided for all of documents matching that query.
