Hi everybody
I have a simple but (for me) annoying problem. I'm happy user of Solr
1.4 with a small collection of documents. Today one of the users has
reported that a query returns documents that are non-pertinent to the
expression. I have spanish, portuguese and english text inside the
collection. Using the Solr administration interface I've found that
she was right, if I search for the spanish term "represion", I found
just only the word root, I mean it returns every document with the
term "repres". Using the admin-debug search I found this:
<lst name="debug">
<str name="rawquerystring">description:represion</str>
<str name="querystring">description:represion</str>
<str name="parsedquery">description:repres</str>
<str name="parsedquery_toString">description:repres</str>
the "ion" part of the term was deleted by the query parser. The first
question is: I don´t know now where should I see to correct this, at
the schema.xml or at the solrconfig.xml.
At schema, description is
<field name="description" type="text" indexed="true"
multiValued="true" stored="true"/>
and text is:
<fieldtype name="text" class="solr.TextField" positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.ISOLatin1AccentFilterFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt"/>
<filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1" generateNumberParts="1" catenateWords="1"
catenateNumbers="1" catenateAll="0"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.EnglishPorterFilterFactory"
protected="protwords.txt"/>
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.ISOLatin1AccentFilterFactory"/>
<filter class="solr.SynonymFilterFactory"
synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt"/>
<filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1" generateNumberParts="1" catenateWords="0"
catenateNumbers="0" catenateAll="0"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.EnglishPorterFilterFactory"
protected="protwords.txt"/>
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>
</fieldtype>
The only thing that is suspicious to me is the EnglishPorter. I've
deleted from the configuration but nothing changes. Should I reindex
the collection to see the changes? Should I delete also from the index
section? What I will loose deleting English porter?
Thanks a lot for the help
