To say some of that more specifically, the keyword tokenizer returns the
full input as one long token (embedded spaces and all) and the regex filter
modifies that one long token (replacing some characters with spaces) but it
remains as one long token, so the final output is a single token with no
true tokenization, and without tokenization, "labelled" is never output as a
discrete token, and hence never seen by the suggester.

Isn't your phrase_suggest analyzer always going to treat every input string
as one single token, and that single token is what the suggester is
returning? And, that single token starts with "th", not "lab"? Is that what
you want?
Try using the Solr admin UI analyzer page to verify how the analyzer is
working.

Subject: Troubles defining suggester/ understanding results
I am having troubles defining suggester for auto complete after reading the
tutorial.
Here are my shcema definitions:
<field name="PackageName" type="text_en" indexed="true" stored="true"
required="true"/>
<field name="PackageVersionComments" type="text_en" indexed="true"
stored="true" required="false"/>
...
<field name="SKUDescription" type="text_en" indexed="true"
stored="true" required="false" multiValued="true"/>
I also added two field types
<fieldtype name="text" class="solr.TextField">
<analyzer>
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldtype>
<fieldtype name="phrase_suggest" class="solr.TextField">
<analyzer>
<tokenizer class="solr.KeywordTokenizerFactory"/>
<filter class="solr.PatternReplaceFilterFactory"
pattern="([^\p{L}\p{M}\p{N}\p{Cs}]*[\p{L}\p{M}\p{N}\p{Cs}\_]+:)|([^\p{L}\p{M}\p{N}\p{Cs}])+"
replacement=" " replace="all"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.TrimFilterFactory"/>
</analyzer>
</fieldtype>
Now since I want to make suggestions from multiple fields and I cant
declare two fields I defined :
and copied three of the fields using :
Problems:
1. everything loads pretty well. but copying the fields to a new fields
just inflate my index. is there a possiblity to define the suggester on
mopre then one field? 2. I cant understand the results. querying
http://127.0.0.1:8983/solr/Book/suggest?q=th
returns docs such as
"that are labelled in black on a black background a little black light"
though quering
http://127.0.0.1:8983/solr/vault-Book/suggest?q=lab
doesnt return anything.
lab is found in the previous result as well.
What is the problem?
