Hello all,
I'm getting a strange suggestion for a purposely mistyped word in Solr 1.4.1
I search for the term "snia", and I would expect the term "sina" to be
suggested, as this is a fairly common word in quite a bit of the indexed
documents.
Instead, I'm getting india as a suggestion, which is only indexed once, and
has (at least as far as my understanding of the algorithm goes) a greater
Levenshtein distance than sina.
The configuration for the spellchecker is pretty straigforward, basically
taken directly from the examples:
<searchComponent name="spellcheck" class="solr.SpellCheckComponent">
<str name="queryAnalyzerFieldType">textSpell</str>
<lst name="spellchecker">
<str name="name">default</str>
<str name="field">spell</str>
<str name="buildOnOptimize">true</str>
<str name="buildOnCommit">true</str>
<str name="spellcheckIndexDir">./spellchecker1</str>
<str name="comparatorClass">freq</str>
<float name="thresholdTokenFrequency">.01</float>
</lst>
I have tried to use the comparatorClass there (as frequency would probably
yield better results for me), but only saw after that it is only available
for Solr4.
The complete suggestions I get from the standard search component is:
<lst name="spellcheck">
<lst name="suggestions">
<lst name="snia">
<int name="numFound">5</int>
<int name="startOffset">0</int>
<int name="endOffset">4</int>
<int name="origFreq">0</int>
<arr name="suggestion">
<lst>
<str name="word">india</str>
<int name="freq">1</int>
</lst>
<lst>
<str name="word">sina</str>
<int name="freq">30</int>
</lst>
<lst>
<str name="word">soa</str>
<int name="freq">4</int>
</lst>
<lst>
<str name="word">unit</str>
<int name="freq">3</int>
</lst>
<lst>
<str name="word">sei</str>
<int name="freq">2</int>
</lst>
</arr>
</lst>
<bool name="correctlySpelled">false</bool>
</lst>
</lst>
Apart from the india suggestions, the other ones are okay, though I need to
tune my stopwords for the (German) indexer a bit more.
Is there any explanation why india is chosen over sina in the suggestions?
Is there anything I can tweak in the configuration to get the desired
result?
If some information is missing, don't hestitate to ask, I will try to supply
it then.
Many thanks in advance,
Jens
