I assume if your user queries "delll" and it breaks it into pieces like "de l l
l", then you're probably using WordBreakSolrSpellChecker in addition to
DirectSolrSpellChecker, right? If so, then you can specify "minBreakLength" in
solrconfig.xml like this:
<searchComponent name="spellcheck" class="solr.SpellCheckComponent">
... spellcheckers here ...
<lst name="spellchecker">
<str name="name">wordbreak</str>
<str name="classname">solr.WordBreakSolrSpellChecker</str>
... parameters here ...
<int name="minBreakLength">5</int>
</lst>
</searchComponent>
One note is that both DirectSolrSpellChecker and WordBreakSolrSpellChecker
operate directly on the terms dictionary and do not have a separate dictionary
like IndexBasedSpellChecker. The only way to prevent a word from being in the
dictionary then is to filter this out in the analysis chain. For instance, if
you use <copyField /> to build a field just for spellchecking, you can use
LengthFilterFactory to remove the short terms. See
http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#solr.LengthFilterFactory

Subject: how to avoid single character to get indexed for directspellchecker
dictionary
hi all
I am using solr directspellcheker for spell suggestions using raw analyses
for indexing but I have some fields which have single characters like l L
so its is been indexed in the dictionary and when I am using this for
suggestions for query like delll its suggesting de and l l l as the spell
correction as my index has de and l as single characters in the fields.
please help.
thanks

Rohan
