Jack,
I've already tried that, here's my query:
<str name="debugQuery">on</str>
<str name="indent">on</str>
<str name="start">0</str>
<str name="q">0_extrafield1_n:20454</str>
<str name="q.op">OR</str>
<str name="rows">10</str>
<str name="version">2.2</str>
Here's the parsed query:
<str name="parsedquery_toString">0_extrafield1_n:"2o45 o454 2o454"</str>
Here's the applicable lines from schema.xml:
<fieldType name="ngram" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt" enablePositionIncrements="true"/>
<filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt"
ignoreCase="true" expand="true"/>
<filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1" generateNumberParts="1" catenateWords="1"
catenateNumbers="1" catenateAll="1" splitOnCaseChange="0"
splitOnNumerics="0" preserveOriginal="0"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.PatternReplaceFilterFactory" pattern="0"
replacement="o" replace="all"/>
<filter class="solr.PatternReplaceFilterFactory" pattern="1|l"
replacement="i" replace="all"/>
<filter class="solr.NGramFilterFactory" minGramSize="4"
maxGramSize="16"/>
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.NGramTokenizerFactory" minGramSize="4"
maxGramSize="16" />
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt" enablePositionIncrements="true"/>
<filter class="solr.PatternReplaceFilterFactory"
pattern="[^A-Za-z0-9]+" replacement="" replace="all"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.PatternReplaceFilterFactory" pattern="0"
replacement="o" replace="all"/>
<filter class="solr.PatternReplaceFilterFactory" pattern="1|l"
replacement="i" replace="all"/>
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>
</fieldType>
<dynamicField name="*_n" type="ngram" indexed="true" stored="true"
autoGeneratePhraseQueries="false" />
