Subject [Solr Wiki] Update of "HighlightingParameters" by TomBurtonWest
Date Mon, 13 Jun 2011 21:23:09 GMT
Dear Wiki user,

The "HighlightingParameters" page has been changed by TomBurtonWest:

  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.

  The text which appears before and after a highlighted term when using the `simple` formatter.
This parameter accepts per-field overrides.
  
  The default values are "`<em>`" and "`</em>`"
+ This parameter makes sense for Highlighter only. Use hl.tag.pre and hl.tag.post for FastVectorHighlighter
(see example under hl.fragmentsBuilder)
  
  == hl.fragmenter ==
  Specify a text snippet generator for highlighted text.  The standard fragmenter is `gap`
(which is so called because it creates fixed-sized fragments with gaps for multi-valued fields).
 Another option is `regex`, which tries to create fragments that "look like" a certain regular
expression.  This parameter accepts per-field overrides.  <!> [[Solr1.3]] This parameter
makes sense for Highlighter only.

  Factor by which the regex fragmenter can stray from the ideal fragment size (given by `hl.fragsize`)
to accomodate the regular expression.  For instance, a slop of `0.2` with fragsize of `100`
should yield fragments between `80` and `120` characters in length.  It is usually good to
provide a slightly smaller fragsize when using the `regex` fragmenter.
  
  The default value is "`.6`"
+ This parameter makes sense for Highlighter only.
  
  == hl.regex.pattern ==
  The regular expression for fragmenting.  This could be used to extract sentences (see example
`solrconfig.xml`)
+ This parameter makes sense for Highlighter only.
  
  == hl.regex.maxAnalyzedChars ==
  Only analyze this many characters from a field when using the regex fragmenter (after which,
the fragmenter produces fixed-sized fragments).  Applying a complicated regex to a huge field
is expensive.
  
  The default value is "`10000`".
+ This parameter makes sense for Highlighter only.
