Hi, i’m using Django Haystack 2.1.0 with Solr 4.8.1 in an auto-complete application. I’ve noticed that words containing digits are not being matched. Examples are ‘B2B’, ‘PSG4’, and ‘5S_rRNA’. The words match up to the occurrence of the digit and fail starting with the digit.
Below is what I believe to be the relevant chunk from the Haystack-generated Solr schema.xml. If I need to include more, let me know. COPB2 <fieldType name="edge_ngram" class="solr.TextField" positionIncrementGap="1"> <analyzer type="index"> <tokenizer class="solr.WhitespaceTokenizerFactory" /> <filter class="solr.LowerCaseFilterFactory" /> <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0" splitOnCaseChange="1"/> <filter class="solr.EdgeNGramFilterFactory" minGramSize="2" maxGramSize="15" side="front" /> </analyzer> <analyzer type="query"> <tokenizer class="solr.WhitespaceTokenizerFactory" /> <filter class="solr.LowerCaseFilterFactory" /> <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0" splitOnCaseChange="1"/> </analyzer> </fieldType> Can I get this to work by tweaking the WordDelimiterFilterFactory attributes somehow, or do I need to do something else? Thanks, Kevin
