Well, what is happening is that the query parser detects a "prefix query" 
("series*") and then does a term analysis on the prefix alone ("series"), 
which you probably have in your stop words list, which causes the analyzer 
to return... nothing, which is what the error is complaining about.

You can workaround my querying for serie* (as long as "serie" is not also a 
stop word.

In any case, technically, the stop filter is doing exactly what it is 
supposed to do.

In all honesty, I can't imagine a context in which a noun such as "series" 
would be on a stop word list. What's your thinking on why it is there??

Subject: solr.StopFilterFactory doesn't work with wildcard

Good day!

I have a problem with the solr.StopFilterFactory and wildcard text search.
For query like this 'hp* pavilion* series* d4*', where 'series' is stop
word, I recieve error:
'analyzer returned no terms for multiTerm term: series'
But for query like this 'hp* pavilion* series d4*', I recieve expected
results.

Could you help me?

I have field type for search as below:

<fieldType name="search_string" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="query">
<tokenizer class="solr.WhitespaceTokenizerFactory" />
<filter class="solr.StopFilterFactory" words="stopwords.txt"
ignoreCase="true"/>
</analyzer>
<analyzer type="multiterm">
<tokenizer class="solr.WhitespaceTokenizerFactory" />
<filter class="solr.StopFilterFactory" words="stopwords.txt"
ignoreCase="true"/>
</analyzer>
</fieldType>

Solr version:

solr-spec 4.0.0.2012.10.06.03.04.33
solr-impl 4.0.0 1394950 - rmuir - 2012-10-06 03:04:33
