Hello,
solr.KeywordTokenizerFactory seems splitting by whitespaces though according
SOLR documentation shouldn't do that.
For example I have the following configuration for the fields "proj_name" and
"proj_name_sort":
<field name="proj_name" type="sortable_text_general" indexed="true"
stored="true"/>
<field name="proj_name_sort" type="string_sort" indexed="true" stored="false"/>
......
<copyField source="proj_name" dest="proj_name_sort" />
..................
<fieldType name="string_sort" class="solr.TextField" sortMissingLast="true"
omitNorms="true">
<analyzer>
<!-- KeywordTokenizer does no actual tokenizing, so the entire
input string is preserved as a single token
-->
<tokenizer class="solr.KeywordTokenizerFactory"/>
<!-- The LowerCase TokenFilter does what you expect, which can be
when you want your sorting to be case insensitive
-->
<filter class="solr.LowerCaseFilterFactory" />
<!-- The TrimFilter removes any leading or trailing whitespace -->
<filter class="solr.TrimFilterFactory" />
</analyzer>
</fieldType>
There are 3 indexed documents having the respective field values:
proj_name:
Test1008
CR610070 Test1
CR610070 Another Test2
Searching on the "proj_name_sort" giving me the following results:

Please, advise the way to search on un-tokenized fields using partial criteria
and wild cards.
Thanks
