public class RegexFragmenter extends HighlightingPluginBase implements SolrFragmenter
Fragmenter that tries to produce snippets that "look" like a regular
expression.
solrconfig.xml parameters:
hl.regex.pattern: regular expression corresponding to "nice" fragments.hl.regex.slop: how far the fragmenter can stray from the ideal fragment size.
A slop of 0.2 means that the fragmenter can go over or under by 20%.hl.regex.maxAnalyzedChars: how many characters to apply the
regular expression to (independent from the global highlighter setting).maxAnalyzedChars is much lower for this
fragmenter. After this limit is exhausted, fragments are produced in the
same way as GapFragmenterSolrInfoMBean.Category| Modifier and Type | Field and Description |
