Hi, I'm using EdgeNGramFilterFactory to support partial search. Here's my field definition.
<fieldType name="adsktext" class="solr.TextField" positionIncrementGap="100" autoGeneratePhraseQueries="true"> <analyzer type="index"> <tokenizer class= "solr.WhitespaceTokenizerFactory" /> <filter class= "solr.WordDelimiterGraphFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="1" catenateAll= "0" splitOnCaseChange="0" /> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" /> <filter class= "solr.LowerCaseFilterFactory" /> <filter class= "solr.KeywordMarkerFilterFactory" protected="protwords.txt" /> <filter class ="solr.PorterStemFilterFactory" /> <filter class= "solr.EdgeNGramFilterFactory" minGramSize="3" maxGramSize="30" /> <filter class="solr.RemoveDuplicatesTokenFilterFactory" /> </analyzer> <analyzer type="query"> <tokenizer class="solr.WhitespaceTokenizerFactory" /> <filter class="solr.WordDelimiterGraphFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="1" catenateAll= "0" splitOnCaseChange="0" /> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" /> <filter class= "solr.SynonymGraphFilterFactory" synonyms="synonyms/synonyms.txt" ignoreCase ="true" expand="true" /> <filter class="solr.LowerCaseFilterFactory" /> < filter class="solr.KeywordMarkerFilterFactory" protected="protwords.txt" /> <filter class="solr.PorterStemFilterFactory" /> <filter class= "solr.RemoveDuplicatesTokenFilterFactory" /> </analyzer> </fieldType> I run into an issue when I'm trying a numeric terms in search. For e.g. if I search for *72 hours*, EdgeNGramFilterFactory ignores 72 and only stores *hou* and *hour* in index. Since I'm using AND operator, the query fails to match *72 *hours. I can enable EdgeNGramFilterFactory in the query chain, but I thought that would be an un-necessary overhead. Is there a reason why 72 is ignored and what'll be the best way to address this scenario? Any pointers will be appreciated. Thanks, Shamik
