Maybe you just want to use the white space tokenizer - the standard
tokenizer treats the at-sign as if a space.
See:
http://lucene.apache.org/core/4_0_0/analyzers-common/org/apache/lucene/analysis/core/WhitespaceTokenizerFactory.html
Or, you could use the "classic" tokenizer which does keep email addresses
and URLs.
http://lucene.apache.org/core/4_0_0/analyzers-common/org/apache/lucene/analysis/standard/ClassicTokenizerFactory.html
And, there is some variant of the new standard tokenizer that also preserves
email addresses and URLs - but it's name is too complex for me to recommend
it with a straight face: UAX29URLEmailTokenizerFactory.
See:
http://lucene.apache.org/core/4_0_0/analyzers-common/org/apache/lucene/analysis/standard/UAX29URLEmailTokenizerFactory.html

Hi Jack,
We have an email field defined like this:-
<fieldType name="text_email" class="solr.TextField"
positionIncrementGap="100">
<analyzer>
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.PatternReplaceFilterFactory"
pattern="\." replacement=" DOT " replace="all"/>
<filter class="solr.PatternReplaceFilterFactory" pattern="@"
replacement=" AT " replace="all"/>
<filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1" generateNumberParts="1"
catenateWords="0" catenateNumbers="0"
catenateAll="0" splitOnCaseChange="0"/>
</analyzer>
<analyzer type="multiterm">
<tokenizer class="solr.KeywordTokenizerFactory" />
</analyzer>
</fieldType>
A query like [emailAddress : bob*] would match b...@bob.com, but queries
which include any special characters like [bob@], [bob@*] and [bob@bob.*]
will not match any email addresses.
Yes, I tried the multi-term and it does not fix the issue. Any thots?
Thanks,
Balaji
