URLs and email addresses in solr search results

Question

I have a solr search that returns contextual highlight results showing a URL and emails with a space after periods - for example, "www. Google. Com" or "email @google. Com". Anyway, to disable this, as usual? Thank.

Query:

/solr/core1/select?q=email&start=0&rows=10&sort=score+desc&fq=%28categories%3A%28*8*%29%29&wt=javabin&version=2

highlight the section in the configuration:

<searchComponent class="solr.HighlightComponent" name="highlight">
<highlighting>
  <!-- Configure the standard fragmenter -->
  <!-- This could most likely be commented out in the "default" case -->
  <fragmenter name="gap" 
              default="true"
              class="solr.highlight.GapFragmenter">
    <lst name="defaults">
      <int name="hl.fragsize">250</int>
    </lst>
  </fragmenter>

  <!-- A regular-expression-based fragmenter 
       (for sentence extraction) 
    -->
  <fragmenter name="regex" 
              class="solr.highlight.RegexFragmenter">
    <lst name="defaults">
      <!-- slightly smaller fragsizes work better because of slop -->
      <int name="hl.fragsize">70</int>
      <!-- allow 50% slop on fragment sizes -->
      <float name="hl.regex.slop">0.5</float>
      <!-- a basic sentence pattern -->
      <str name="hl.regex.pattern">[-\w ,/\n\&quot;&apos;]{20,200}</str>
    </lst>
  </fragmenter>

  <!-- Configure the standard formatter -->
  <formatter name="html" 
             default="true"
             class="solr.highlight.HtmlFormatter">
    <lst name="defaults">

      <str name="hl.simple.post"><![CDATA[</b>]]></str>
    </lst>
  </formatter>

  <!-- Configure the standard encoder -->
  <encoder name="html" 
           class="solr.highlight.HtmlEncoder" />

  <!-- Configure the standard fragListBuilder -->
  <fragListBuilder name="simple" 
                   default="true"
                   class="solr.highlight.SimpleFragListBuilder"/>

  <!-- Configure the single fragListBuilder -->
  <fragListBuilder name="single" 
                   class="solr.highlight.SingleFragListBuilder"/>

  <!-- default tag FragmentsBuilder -->
  <fragmentsBuilder name="default" 
                    default="true"
                    class="solr.highlight.ScoreOrderFragmentsBuilder">
    <!-- 
    <lst name="defaults">
      <str name="hl.multiValuedSeparatorChar">/</str>
    </lst>
    -->
  </fragmentsBuilder>
</highlighting>

Answer 1

Try using the UAX29URLEmailTokenizerFactory tokenizer , which is similar to the standard tokenizer, but can recognize email addresses, URLs, domain names and IPv4 / IPv6 addresses, Example from the Solr reference guide:
