This is what we use for our autosuggest field in Solr 3.4. It works for us as
you describe below.
<fieldType name="autocomplete_edge" class="solr.TextField">
<analyzer type="index">
<tokenizer
class="solr.KeywordTokenizerFactory"/>
<charFilter
class="solr.MappingCharFilterFactory" mapping="mapping-ISOLatin1Accent.txt"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter
class="solr.PatternReplaceFilterFactory" pattern="([\.,;:-_])" replacement=" "
replace="all"/>
<filter class="solr.EdgeNGramFilterFactory"
maxGramSize="30" minGramSize="1"/>
<filter
class="solr.PatternReplaceFilterFactory" pattern="([^\w\d])" replacement=""
replace="all"/>
</analyzer>
<analyzer type="query">
<tokenizer

<charFilter
class="solr.MappingCharFilterFactory" mapping="mapping-ISOLatin1Accent.txt"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter
class="solr.PatternReplaceFilterFactory" pattern="([\.,;:-_])" replacement=" "
replace="all"/>
<filter
class="solr.PatternReplaceFilterFactory" pattern="([^\w\d])" replacement=""
replace="all"/>
<filter
class="solr.PatternReplaceFilterFactory" pattern="^(.{30})(.*)?"
replacement="$1" replace="all"/>
</analyzer>
</fieldType>

EdgeNGramFilter
I tried adding *PatternReplaceFilterFactory *in index section but it is not
working
Example itemName data can be :
- "ABC E12" : if user types "ABCE" suggestion should be "ABC E12"
- "ABCE_12" : if user types "ABCE1" suggestion should be "ABCE_12"
<field name="itemName" type="text_general_edge_ngram" indexed="true"
stored="true" multiValued="false" />
<fieldType name="text_general_edge_ngram" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.KeywordTokenizerFactory"/>
*<filter class="solr.PatternReplaceFilterFactory" pattern="(\s+)"
replacement="" replace="all" />*
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.EdgeNGramFilterFactory" minGramSize="1"
maxGramSize="15" side="front"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.LowerCaseTokenizerFactory"/>
</analyzer>
</fieldType>
