Hi,
the following seems to work pretty well.
<fieldType name="text_ws" class="solr.TextField"
positionIncrementGap="100">
<analyzer>
<tokenizer class="solr.KeywordTokenizerFactory" />
<filter class="solr.ShingleFilterFactory"
maxShingleSize="4" outputUnigrams="true"
outputUnigramIfNoNgram="false" />
</analyzer>
</fieldType>
<!-- A text field that uses WordDelimiterFilter to enable splitting and
matching of
words on case-change, alpha numeric boundaries, and non-alphanumeric
chars,
so that a query of "wifi" or "wi fi" could match a document
containing "Wi-Fi".
Synonyms and stopwords are customized by external files, and
stemming is enabled.
The attribute autoGeneratePhraseQueries="true" (the default) causes
words that get split to
form phrase queries. For example, WordDelimiterFilter splitting
text:pdp-11 will cause the parser
to generate text:"pdp 11" rather than (text:PDP OR text:11).
NOTE: autoGeneratePhraseQueries="true" tends to not work well for
non whitespace delimited languages.
-->
<fieldType name="text" class="solr.TextField" positionIncrementGap="100"
autoGeneratePhraseQueries="true">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<!-- in this example, we will only use synonyms at query time
<filter class="solr.SynonymFilterFactory"
synonyms="index_synonyms.txt" ignoreCase="true" expand="false"/>
-->
<!-- Case insensitive stop word removal.
add enablePositionIncrements=true in both the index and query
analyzers to leave a 'gap' for more accurate phrase queries.
-->
<filter class="solr.StopFilterFactory"
ignoreCase="true"
words="stopwords.txt"
enablePositionIncrements="true"
/>

<copyField source="cat" dest="text"/>
<copyField source="subject" dest="text"/>
<copyField source="summary" dest="text"/>
<copyField source="cause" dest="text"/>
<copyField source="status" dest="text"/>
<copyField source="urgency" dest="text"/>
I ingest the source fields as text_ws (I know I've changed it a bit) and
then copy the field to text. This seems to do what you are asking for.
