How can i get collect stemmed query?
Hi~. I'm beginner who wanna make search system by using solr 1.4.1 and lucene
2.92.
I got a collect lucene query from my custom Analyzer and filter from given
query,
but no result displayed.
Here is my Analyzer source.
------------------------------------------------------------------------------------------------------
public class KLTQueryAnalyzer extends Analyzer{
public static final Version LUCENE_VERSION = Version.LUCENE_29;
public static int QUERY_MIN_LEN_WORD_FILTER = 1;
public static int QUERY_MAX_LEN_WORD_FILTER = 40;
public int elapsedTime = 0;
@Override
public TokenStream tokenStream(String paramString, Reader reader) {
StandardTokenizer tokenizer = new StandardTokenizer(
du.utas.mcrdr.ir.lucene.WebDocIR.LUCENE_VERSION, reader );
TokenStream tokenStream = new LengthFilter( tokenizer,
QUERY_MIN_LEN_WORD_FILTER,
QUERY_MAX_LEN_WORD_FILTER );
tokenStream = new LowerCaseFilter( tokenStream );
//My custom stemmer method
KLTSingleWordStemmer stemer = new
KLTSingleWordStemmer(QUERY_MIN_LEN_WORD_FILTER, QUERY_MAX_LEN_WORD_FILTER);
//My custom analyzer filter. this filter return sub-merged query.
//ex) INPUT : flyaway
// RETURN VALUE : fly +body:away
tokenStream = new KLTQueryStemFilter( tokenStream, stemer, this );
return tokenStream;
}
}
------------------------------------------------------------------------------------------------------
example query) Input User query : +body:flyaway
Expected analyzed query : +body:fly +body:away
INDEXED DATA : body> fly away
I'm expecting 1 docs returned from index, but I have no result returned.
explain my custom flow
1. User input query : +body:flyaway
2. Analyzer return that : fly +body:away
3. Solr attach search field tag at filter returned query : "+body" as i
defined at schema.xml.(default operator "AND")
4. I'm indexed 1 docs that have field name "body", has containing this
phrase "fly away"
5. I expect 1 docs return of result by query "+body:fly +body:away" but 0
docs returned.
What's the problem?? Anybody help me please~ :>

Oh you are constructing the string 'fly +body:away' in your StemFilter?
Just to make sure, does this q=+body:(fly away) return your document?
And analysis.jsp (at query time) displays 'fly +body:away' from the string 'flyaway'?
I don't know why are you doing this but your stemfilter should return only terms, not field names attached to it.
Maybe you can find this useful so that you can do what you want without writing custom code.

Thanks for your reply :)
1. I tested that "q=*:*&fl=body" , 1 doc returned as result as I expected.
2. I'm edit my scheme.xml as you instructed.
<analyzer type="query"
class="com.testsolr.ir.customAnalyzer.MyCustomQueryAnalyzer">
//No filter description.
</analyzer>
but no result returned.
3. I wonder that...
Tipically Tokenizer and filter flow was
1) Input stream provide text stream to tokenizer or filter.
2) tokenizer or filter get a token, and processed token and offset
attribute info has returned.
3) offset attributes has the infomation of token's.
This is a part of tipical filter src that I thought.
------------------------------------------------------------------------------------
public class CustomStemFilter extends TokenFilter {
private MyCustomStemer stemmer;
private TermAttribute termAttr;
private OffsetAttribute offsetAttr;
private TypeAttribute typeAttr;
private Hashtable<String,String> reserved = new
Hashtable<String,String>();
public CustomStemFilter( TokenStream tokenStream, boolean isQuery,
MyCustomStemer stemmer ){
super( tokenStream );
this.stemmer = stemmer;
termAttr = (TermAttribute) addAttribute(TermAttribute.class);
offsetAttr = (OffsetAttribute)
addAttribute(OffsetAttribute.class);
typeAttr = (TypeAttribute)
addAttribute(TypeAttribute.class);
addAttribute(PositionIncrementAttribute.class);
//Some of my custom logic here.
//do something.
}
private MyCustomStemmer stemmer = new MyCustomStemmer();
public boolean incrementToken() throws IOException {
clearAttributes();
if (!input.incrementToken())
return false;
StringBuffer queryBuffer = new StringBuffer();
//stemming logic here.
//generated query string has append to queryBuffer.
termAttr.setTermBuffer(queryBuffer.toString(), 0,
queryBuffer.length());
offsetAttr.setOffset(0, queryBuffer.length());
offSet += queryBuffer.length();
typeAttr.setType("word");
return true;
}
}
------------------------------------------------------------------------------------
※ MyCustomStemmer analyze input string "flyaway" to query string :
fly +body:away
and return it.
At index time, contents to be searched is normally analyzed and
indexed as below.
a) Contents to be indexed : fly away
b) Token "fly" and length of "fly" = 3(Has been setup by offset
attribute method)
has returned by filter or analyzer.
c) Next token "away" and length of "away" = 4 has returned.
I think it's a general index flow.
But, I customized MyCustomFilter that filter generate query string,
not a token.
In the process, offset value has changed : query's length, not a
single token's length.
I wonder that value to be set up by offsetAttr.setOffset() method
has influence on search result on using solr?
(I tested this on main page's query input box at
http://localhost:8983/solr/admin/ )

Re: How can i get collect stemmed query?
Posted by Ahmet Arslan <io...@yahoo.com>.
rawquerystring = +body:flyaway
parsedquery = +body:fly +body:away
shows that your custom filter is working as you expected.
However you are using different tokenizers in query (standardtokenizer hard-coded) and index (whitespacetokenizer) time. That may cause numFound=0.
For example if your indexed document contains 'fly, away' in its body field, your query won't return it. Because of comma.
admin/analysis.jsp shows indexed tokens.
You can issue a *:* query to see if that document really exists.
q=*:*&fl=body
Your query analyzer definition should look like :
<analyzer type="query" class="com.testsolr.ir.customAnalyzer.MyCustomQueryAnalyzer" />
you cannot have both an analyzer and a tokenizer at the same time.
Once you get this working, in your case it is better to write a custom filter factory plug-in and define query analyzer using it. ( for performance reason)
And you can load your plug-in easier : http://wiki.apache.org/solr/SolrPlugins#How_to_Load_Plugins
<analyzer type="query">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.LengthFilterFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="com.testsolr.ir.KLTQueryStemFilter"/>
</analyzer>

Re: How can i get collect stemmed query?
Posted by Jerad <ag...@naver.com>.
Oops, I'm Sorry! I found some mistakes on previous posted source.( Main class
name has been wrong :<)
This is the collect analyzer source.
-------------------------------------------------------------------------------------------------------
public class MyCustomQueryAnalyzer extends Analyzer{
public static final Version LUCENE_VERSION = Version.LUCENE_29;
public static int QUERY_MIN_LEN_WORD_FILTER = 1;
public static int QUERY_MAX_LEN_WORD_FILTER = 40;
public int elapsedTime = 0;
@Override
public TokenStream tokenStream(String paramString, Reader reader) {
StandardTokenizer tokenizer = new StandardTokenizer(
du.utas.mcrdr.ir.lucene.WebDocIR.LUCENE_VERSION, reader );
TokenStream tokenStream = new LengthFilter( tokenizer,
QUERY_MIN_LEN_WORD_FILTER,
QUERY_MAX_LEN_WORD_FILTER );
tokenStream = new LowerCaseFilter( tokenStream );
//My custom stemmer method
MyCustomSingleWordStemmer stemer = new

// RETURN VALUE : fly +body:away
tokenStream = new KLTQueryStemFilter( tokenStream, stemer, this );
return tokenStream;
}
}
-------------------------------------------------------------------------------------------------------
[Additional info]
1. MyCustomQueryAnalyzer made outside of Solr.
I made this analyzer outside of the solr package and make it to ~.jar
and located at
~/Solr/example/work/Jetty_0_0_0_0_8982_solr.war__solr__-2c5peu/webapp/WEB-INF/lib
2. I edited field type and field name in scheme.xml which to be searched.
<field name="body" type="textTp" indexed="true" stored="true"
omitNorms="true"/>
<fieldType name="textTp" class="solr.TextField">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
<analyzer type="query"
class="com.testsolr.ir.customAnalyzer.MyCustomQueryAnalyzer">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
</analyzer>
</fieldType>
This is my custom scheme.xml and custom search field type.
3. I've got this xml result when I append &debugQuery=on to my search url.

Re: How can i get collect stemmed query?
Posted by Ahmet Arslan <io...@yahoo.com>.
Are you using KLTQueryAnalyzer outside of the Solr? (pre-process)
Or you defined a fieldType in schema.xml that uses KLTQueryAnalyzer?
Can you append &debugQuery=on to your search url and paste output?
