Hmm, as far as I can tell, neither of those should give suggestions,
as they both have edit distances less than 0.70.
In the Lucene code, I ran the following test against the Levenshtein
Distance:
public void testJava() throws Exception {
float d1 = sd.getDistance("jav", "java");
System.out.println("di: " + d1);
d1 = sd.getDistance("jav", "javas");
System.out.println("di: " + d1);
}
It prints:
di: 0.6666666
di: 0.3333333
Is "javas"/"java" the only entry in your spellings?
I presume it does give you the expected suggestion or is it giving you
something else?
Also, what does your query look like?

Hi all
The search with an accuracy defined by user in SOLRCONFIG.XML is not
working
for me. I have provided an example below.
Please let me know your valuable suggestion.
For example:
Accuracy tag is used in Solrconfig.xml file in below manner.
<searchComponent name="spellcheck" class="solr.SpellCheckComponent">
<str name="queryAnalyzerFieldType">textSpell</str>
<lst name="spellchecker">
<str name="name">default</str>
<str name="classname">solr.spelling.FileBasedSpellChecker</str>
<str name="sourceLocation">./spellings.txt</str>
<str name="characterEncoding">UTF-8</str>
<str name="spellcheckIndexDir">./spellcheckerFile</str>
<str name="accuracy">0.70</str> </lst>
</searchComponent>
As per above description, the accuracy set to 0.70 which means to 70%
The keyword ( java ) is stored in spellings.txt file which is also
mentioned
above.
Now if I try to make search for "jav" word, there is no result found
(This
is the problem, why there is no result ??)
where as
If I replace (java) keyword with (javas) in spellings.txt file and
keep the
accuracy 0.70 ...
Now if I try to make search for "jav" word, I start getting the
results ...
What is this behaviour ?? Does anyone knows what is the reason ...
Regards,
Navdeep
