I am working on an application that requires me to use Solr for the first time. I set it up, indexed the correct data, and queried as I would like, but I cannot get the spellchecker component to work properly. No matter what I request, spell checking will not return any suggestions. I have included the relevant parts of my solrconfig and schema.xml.
schema.xml
<fieldType name="textSpell" class="solr.TextField" positionIncrementGap="100" omitNorms="true"> <analyzer type="index"> <charFilter class="solr.HTMLStripCharFilterFactory"/> <tokenizer class="solr.StandardTokenizerFactory"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/> <filter class="solr.LowerCaseFilterFactory"/> <filter class="solr.StandardFilterFactory"/> </analyzer> <analyzer type="query"> <tokenizer class="solr.StandardTokenizerFactory"/> <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/> <filter class="solr.LowerCaseFilterFactory"/> <filter class="solr.StandardFilterFactory"/> </analyzer> </fieldType> <field name="spell" type="textSpell" indexed="true" stored="true" />
solrconfig.xml

When I go to http://localhost:8983/solr/select/?q=query&spellcheck.build=true , then look at the files generated in / path / to / my / spell / index, there is segment.gen and segments_1, both of which contain only a few bytes of binary data. Then, when I enter the query and add &spellcheck=true to the query string, I get no suggestions, regardless of my query:
<lst name="spellcheck"> <lst name="suggestions"/> </lst>
Any idea what is going on here?
