Oleg Gnatovskiy commented on SOLR-572:
--------------------------------------
Hey guys I created a dictionary index from the following XML file:
<add>
<doc>
<field name="id">1000000000</field>
<field name="word">pizza</field>
</doc>
<doc>
<field name="id">1000000001</field>
<field name="word">club</field>
</doc>
<doc>
<field name="id">1000000002</field>
<field name="word">bar</field>
</doc>
</add>
My config is the following:
<searchComponent name="spellcheck"
class="org.apache.solr.handler.component.SpellCheckComponent">
<lst name="dictionary">
<str name="name">default</str>
<str name="type">index</str>
<str name="field">word</str>
<!--<str name="indexDir">c:/temp/spellindex</str>-->
</lst>
</searchComponent>
and word is defined in schema.xml as:
<field name="word" type="string" index="true" stored="true"
required="false"/>
When I run a query with the following URL:
http://localhost:8983/solr/select/?q=barr&spellcheck=true&spellcheck.dictionary=default&spellcheck.count=10
I get the following response:
lst name="spellcheck">
<lst name="suggestions">
<int name="numFound">1</int>
<arr name="barr">
<str>bar</str>
</arr>
</lst>
</lst>
which is what I expect.
However with this URL:
http://wil1devsch1.cs.tmcs:8983/solr/select/?q=bar&spellcheck=true&spellcheck.dictionary=default&spellcheck.count=10
where bar is correctly spelled, I get the following:
<lst name="spellcheck">
<lst name="suggestions">
<int name="numFound">1</int>
<arr name="bar">
<str>barr</str>
</arr>
</lst>
</lst>
Could you please tell me where the word "barr" is coming from, and why it is
being suggested?
Thanks!
