Hi,
Right now when I perform a sort I am getting result as following:
"[\"18 hotfix3\"]"
"[\"Godzilla\"]"
"[\"Godzilla, King of the Monsters!\"]"
"[\"Harry Potter and the Sorcerers Stone\"]"
"[\"How to Train Your Dragon\"]"
"[\"Jurassic Park\"]"
"[\"My Big Fat Greek Wedding\"]"
"[\"National Treasure\"]"
"[\"Palmer\"]"
"[\"Patch Adams\"]"
"[\"Rajan\"]"
"[\"Sanity\"]"
"[\"Stardust\"]"
"[\"Superman\"]"
"[\"The Amazing Spider-Man 2\"]"
"[\"The Godfather\"]"
"[\"The Lord of the Rings: The Fellowship of the Ring\"]"
"[\"The Matrix\"]"
"[\"V for Vendetta\"]"
"[\"abcdefgh\"]"
"[\"autoui1466571231695\"]"
"[\"autoui1466605339320\"]"
"[\"name\"]"
"[\"test\"]"
"[\"test2\"]"
The field type has been defined as follows :
<fieldType class="org.apache.solr.schema.TextField" name="TextField"
sortMissingLast="true">
<analyzer>
<tokenizer class="solr.KeywordTokenizerFactory"/>
<!-- lower case everything -->
<filter class="solr.LowerCaseFilterFactory"/>
<!-- remove lead/trail whitespace -->
<filter class="solr.TrimFilterFactory"/>
<!-- pad and trim numbers to an even 6 digits with leading 0's
-->
<filter class="solr.PatternReplaceFilterFactory"
pattern="(\d+)" replacement="00000$1" replace="all"/>
<filter class="solr.PatternReplaceFilterFactory"
pattern="0*([0-9]{6,})" replacement="$1" replace="all"
/>
</analyzer>
</fieldType>
And for sorting purpose we have a dynamic field in place that used the above
field type
<!-- fields for sorting -->
<dynamicField indexed="true" multiValued="false" name="sort_str*"
stored="false" type="SortTextField"/>
