Subject Re: How to implement Spell Checker using Solr?

Firstly, just to make it clear the dictionary is made out of already indexed
terms, rather it is built upon it if you are using *<str
name="classname">solr.IndexBasedSpellChecker</str>* which you are.

Next lot of changes are required for your *solrconfig.xml*

1. <str name="field">spell</str> is the name of the field which will be used
to create your dictionary. Does it exist in schema.xml?

2. <str name="queryAnalyzerFieldType">textSpell</str> is the name of
FieldType used for your dictionary building, as in the <str
name="field">spell</str> should be of type textSpell in schema.xml. Is it

Now for you internal error from crawling. This is most probably because your

say before trying to implement spellcheck this was working.

/Also, I am not too sure so as to how I can make my search work based on the

"form"/"formm", then I should have essentially separate URL created. Does

If you are looking for filebased searching, you are going in the wrong
direction. You are trying to use indexbasedspellchecker class when actually
what you need is

<lst name="spellchecker">
<str name="name">file</str>
<str name="classname">solr.FileBasedSpellChecker</str>
<str name="sourceLocation">spellings.txt</str>
<str name="characterEncoding">UTF-8</str>
<str name="spellcheckIndexDir">./spellcheckerFile</str>

Kindly read about spellchecker more.
