Hi Vincent,
If I recall correctly a wildcard query does not use any of the filters
defined in your fieldtype (search the news group for this). So using a
LowerCaseFilterFactory does not work and you'll need to do the to lower case
transform yourself on the client side (javascript?).
However, if I understand correctly you are trying to build an autocomplete
functionality. The wildcard query may be too slow for this. We are using an
ngram filter for autocompleting over millions of names. This seems to work
fine in test (we are not live yet). Another advantage is that your lower
case issue is solved.
Example config:
<fieldType name="autoComplete" class="solr.TextField"
omitNorms="true">
<analyzer>
<tokenizer
class="solr.WhitespaceTokenizerFactory" />
<filter class="solr.LowerCaseFilterFactory" />
<filter class="solr.EdgeNGramFilterFactory"
maxGramSize="20" minGramSize="2" />
</analyzer>
<analyzer type="query">
<tokenizer
class="solr.WhitespaceTokenizerFactory" />
<filter class="solr.LowerCaseFilterFactory" />
<filter class="solr.PatternReplaceFilterFactory"
pattern="^(.{20})(.*)?"
replacement="$1" replace="all" />
</analyzer>
</fieldType>
Cheers,
Richard
