Re: Solr with Auto-suggest
Hi Ryan,
I gone through your post
https://issues.apache.org/jira/browse/SOLR-357
where you mention about prefix filter,can you tell me how to use that
patch,and you mentioned to use the code as bellow,
<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="false"/>
<field name="prefix2" type="prefix_token" indexed="true" stored="false"/>
...
<copyField source="name" dest="prefix1"/>
<copyField source="name" dest="prefix2"/>
For using the above code is that you are using EdgeNGramFilterFactory or
PrefixingFilterFactory.
or the above code works for EdgeNGramFilterFactory,i am not clear about
it,with out using the PrefixingFilterFactory patch, is that i can write the
above code.
And the next is "name" in copyFiled is "text" type or "string" type
waiting for your reply,
Regards,
Rekha

There is no such thing in Solr as a PrefixingFilterFactory. Use
EdgeNGramFilterFactory.

Name was a field in his schema. Whatever fields' values you want for
auto-suggest, copy them over to the field.
