It turned out that there is a sorting issue with solr 3.3. As fas as I could trace it down currently:
4 docs in the index and a search for *:* sorting on field dccreator_sort in descending order http://localhost:8983/solr/select?fsv=true&sort=dccreator_sort%20desc&indent=on&version=2.2&q=*%3A*&start=0&rows=10&fl=dccreator_sort result is: ---------- <lst name="sort_values"> <arr name="dccreator_sort"> <str>convertitovistitutonazionaled</str> <str>莊國鴻chuangkuohung</str> <str>zzzzzyyyyyywwwwwwwxxxxxxx</str> <str>abdelhadiyasserabdelfattah</str> </arr> </lst> fieldType: ---------- <fieldType name="alphaOnlySortLim" class="solr.TextField" sortMissingLast="true" omitNorms="true"> <analyzer> <tokenizer class="solr.KeywordTokenizerFactory"/> <filter class="solr.LowerCaseFilterFactory" /> <filter class="solr.TrimFilterFactory" /> <filter class="solr.PatternReplaceFilterFactory" pattern="([\x20-\x2F\x3A-\x40\x5B-\x60\x7B-\x7E])" replacement="" replace="all"/> <filter class="solr.PatternReplaceFilterFactory" pattern="(.{1,30})(.{31,})" replacement="$1" replace="all"/> </analyzer> </fieldType> field: ------ <field name="dccreator_sort" type="alphaOnlySortLim" indexed="true" stored="true" /> According to documentation the sorting is UTF8 but _why_ is the first string at position 1 and _not_ at position 3 as it should be? Following sorting through the code is somewhat difficult. Any hint where to look for or where to start debugging? Regards Bernd
