Nice. Great help. I have added following fields to hold tokens.
<fieldType name="prefix_full" class="solr.TextField"
positionIncrementGap="1">
<analyzer type="index">
<tokenizer class="solr.KeywordTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory" />
<filter class="solr.EdgeNGramFilterFactory"
minGramSize="1" maxGramSize="20"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.KeywordTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory" />
</analyzer>
</fieldType>
<fieldType name="prefix_token" class="solr.TextField"
positionIncrementGap="1">
<analyzer type="index">
<tokenizer
class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory" />
<filter class="solr.EdgeNGramFilterFactory"
minGramSize="1" maxGramSize="20"/>
</analyzer>
<analyzer type="query">
<tokenizer
class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory" />
</analyzer>
</fieldType>
<field name="prefix1" type="prefix_full" indexed="true" stored="true"/>
<field name="prefix2" type="prefix_token" indexed="true" stored="true"/>
<copyField source="content" dest="prefix1"/>
<copyField source="content" dest="prefix2"/>
I am wondering how can I extract tokens? I can see all tokens
http://localhost:8080/solr/admin/schema.jsp page for fields prefix1 and
prefix2 but when I query
http://localhost:8080/solr/select?fl=prefix1,id&q=prefix2:jun%20prefix2:jun to
get the content for prefix2, it does not display any content for prefix2.
Am I doing anything wrong???
