Hi Daniel, Well, searching "inside of words" requires special treatment, because normally searches work on words/terms/tokens.
Make use of the following: $ ff \*NGram\*java ./src/java/org/apache/solr/analysis/EdgeNGramTokenizerFactory.java ./src/java/org/apache/solr/analysis/NGramTokenizerFactory.java ./src/java/org/apache/solr/analysis/NGramFilterFactory.java ./src/java/org/apache/solr/analysis/EdgeNGramFilterFactory.java Use these to create a new field type make Solr tokenize and index your terms as, say, uni-grams. Instead (or in addition to) indexing "Termobyxa", index "T e r m o b y x a". Do the same with the query-time analyzer, and you'll be able to search within words.

We're using it for searching on our site right now though. The configuration is however pretty much based on the example-files that come with Solr and there's one type of search that I can't get to work. Each item has fields called "title" and "description", both of which are of type "text". The type "text" is defined like this in our schema.xml : <fieldType name="text" class="solr.TextField" positionIncrementGap="100"> <analyzer type="index"> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/> <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0"/> <filter class="solr.LowerCaseFilterFactory"/> <filter class="solr.EnglishPorterFilterFactory" protected="protwords.txt"/> <filter class="solr.RemoveDuplicatesTokenFilterFactory"/> </analyzer> <analyzer type="query"> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/> <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0"/> <filter class="solr.LowerCaseFilterFactory"/> <filter class="solr.EnglishPorterFilterFactory" protected="protwords.txt"/> <filter class="solr.RemoveDuplicatesTokenFilterFactory"/> </analyzer> </fieldType> My problem is that if I have an item with "title"="Termobyxa", a search for "Termo" gives me a hit but if I search for "ermo" or "byxa" I get no hit. How do I make it so that this kind of search "inside a word" returns a hit? Sincerely, Daniel Löfquist
