Re: Lucene Error : java.io.FileNotFoundException

[Michael McCandless]

Are you getting exactly the same error (same source files and exact  
same line numbers)?  If so, somehow a Lucene 1.4 JAR is still sneaking  
in.


Lucene 1.4 won't be able to read an index created by Lucene 2.3.   
You'll see exactly that FileNotFoundException because newer versions  
of Lucene write to a segments_N file, while 1.4 tries to open just the  
file "segments".

OK, so I tried that by doing:

SortField sortField = new SortField(
sortFieldName,
new CaseInsensitiveStringSortComparator(), descending
);

where CaseInsensitiveStringSortComparator is:

class CaseInsensitiveStringSortComparator extends SortComparator {
public Comparable getComparable( String termText ) {
return new CaseInsensitiveStringComparable( termText );
}
}

and CaseInsensitiveStringComparable is:

public class CaseInsensitiveStringComparable implements Comparable {

public CaseInsensitiveStringComparable( String s ) {
m_string = s.toLowerCase();
}

public int compareTo( Object o ) {
final String s;
if ( o instanceof CaseInsensitiveStringComparable )
s = ((CaseInsensitiveStringComparable)o).m_string;
else if ( o instanceof String )
s = ((String)o).toLowerCase();
else
throw new ClassCastException();
return m_string.compareTo( s );
}

public boolean equals( Object o ) {
if ( !(o instanceof CaseInsensitiveStringComparable ) )
return false;
final CaseInsensitiveStringComparable c =
(CaseInsensitiveStringComparable)o;
return m_string.equals( c.m_string );
}

public int hashCode() {
return m_string.hashCode();
}

private final String m_string;
}

But when my code runs, I get a NullPointerException in Lucene's  
SortComparator,

line 54 which reads:

return cachedValues[i.doc].compareTo (cachedValues[j.doc]);

because cachedCalues[i.doc] is null.  But why is it null?

I'm not familiar with JBoss' error output, but, maybe this is telling

Re: Search question (newbie)

John,

Thanks, I think I'm getting this now  So you created your own 
BooleanQuery and parsed the string yourself, adding strings as  
TermQuerys etc., rather than using a QueryParser ?


Cheers,

John Griffin wrote:

Chris,

I've had similar requirements in the past. First strip the quotes then
create a BooleanQuery consisting of two separate queries.

1. TermQuery for the first term - Fred
2. PrefixQuery for the second term - Flintstone

When you add each individual query to the BooleanQuery make sure the
BooleanClause.Occur parameter is set to MUST (look at the BooleanQuery API
docs). 


Use the toString() method on the BooleanQuery after it's created to make
sure you did it correctly.

Hi,

Can someone point me in the right direction please?
How can I trap this situation correctly?  I receive user queries like 
this (quotes included):


/from:"fred flintston*"/

Which produces a query string of

/+from:fred  body:flintston/   (where /body/ is the default field)

What I want is:

/+from:fred +from:flintston*/

In other words, I want quoted expressions to be treated as single units..
Thanks for any pointers,

- Chris

Moving to java-user.

Index the field and use the FieldCache.
You don't want to modify core lucene classes for this common use-case.

 You need to understand the inverted index format.  Documents that
 match a term is determined at index time, not at query time.  The .frq
 file lists all documents that match each term.

 TermDocs iterates over all documents that match the term by reading
 the .frq file.

RE: Search question (newbie)

[John Griffin]

Chris,

Yes, when there are multiple types of queries involved (Term & Wildcard in
this case) that's how I handle it. A disadvantage of this is that the user
input must be somewhat restricted since you need to know what's coming.

An important thing to remember is that Wildcard, Prefix and one other I
can't remember at the moment (sorry :>() are not passed through an analyzer.
So, the QueryParser's analyzer has no effect on them.

RE: Lucene Error : java.io.FileNotFoundException

[John Griffin]

Yug,

In the root directory of your JBoss install there is a file that lists all
the jar files your version of JBoss is guaranteed to work with
(jar-versions.xml). It looks like the jar you're trying to add has a
dependency on another jar that doesn't have what it's looking for.

Get on the JBoss forum and with luck someone will know what else you need to
replace.

John G.

Re: Search question (newbie)

[Chris Hostetter]

: How can I trap this situation correctly?  I receive user queries like this
: (quotes included):
: 
:/from:"fred flintston*"/
: 
: Which produces a query string of
: 
:/+from:fred  body:flintston/   (where /body/ is the default field)

either you've left something out, or some aspect of your situation is 
broken ... passing the string you describe -- including the quotes -- to 
QueryParser will not create an optional clause for body:flinston ... it 
will create a PhraseQuery consisting of whatever Terms are produced by 
your analyzer for the (unquoted) string...
 fred flinston*

...note that the "*" is included in the input passed to your analyzer, 
because it has no special meaning inside quotes.

: What I want is:
: 
: /+from:fred +from:flintston*/

that would require both fred, and something starting with flinston, but it 
wouldn't require them to be close together -- you can achieve that by 
overriding QueryParser.getFieldQuery(String,String).  inspect the 
termText, if it contains something that looks prefix/wildcardish, then 
split the input to get what you want, and delegate to 
QueryParser.getPrefixQuery or getWildCardQuery and then combine up your 
parts into a BooleanQuery.

Or... if you want to take it one step further and require that the clauses 
are near eachother, you can construct a MultiPhraseQuery -- but you'll 
need to have access to an IndexReader in your QueryParser so you can 
expand the prefix/wildcard into it's Terms.

Re: Store/Index Email Address in Lucene

[Karl Wettin]

Please show us a couple of examples from the "various type of search"  
you want to be able to handle. The information you supply says nothing  
about your use cases.


In what way do you want to use phrase queries on email addresses? Do  
you want to tokenize parts of a single email address? Or do you want  
to place phrase queries on fields that contains multiple indexed  
single token email addresses? Perhaps a combination? Something else?

Hi there,
I want to index email address in such a way that i can do WildCard,  
Phrase

and Simple search on those items.

for each document i will have email addresses string just like in  
the case

of CC and TO in mails.
for eg "[EMAIL PROTECTED]; [EMAIL PROTECTED]; john hopkings;  
[EMAIL PROTECTED]"


Now what is the best way to store them so that i can do various type  
of

search on them.

Do i need the split the email address first and further split the  
single

email address as well and store them in multiple fields?

What is the best way to deal such case?

Your help is highly anticipated

Thank You
miztaken

Re: Multifield Search with OR and AND on different doc Fields

[Karl Wettin]

4 jul 2008 kl. 08.30 skrev RanjithStar:




My requirement is to search on SEVEN Fields say F1,F2,F3,F4,F5,F6,F7  
having

F1,F2,F3,F4 on one doc index
and F5,F6,F7 on a different doc index


I need to perform a search with ((F1=9 AND F2=4) AND (F3=keyword OR
F4=keyword)) OR (F5=9 AND F6=4 AND F7=keyword)


For normal search I was doing like this:
String[] sFields = { ID1, ID2, TITLE, CONTENT };
String[] sQuery = { id1, id2, sKeyword, sKeyword };
Occur[] flag = { BooleanClause.Occur.MUST, BooleanClause.Occur.MUST,
BooleanClause.Occur.MUST, BooleanClause.Occur.MUST };

Query oQuery = oMultiParser.parse(sQuery, sFields, flag, oAnalyzer) ;
Hits hits = indexSearcher.search(oQuery);



Do you hav some sort of problem with executing the code above? What  
did you expect it to do and what was the results?





How can I modify the above query in such a way that it has to search  
on

different doc Indexes?



I'm sorry, but I don't understand your question.

You want to know how to search in another directory than the one  
associated with your indexSearcher object?

Re: Store/Index Email Address in Lucene

[miztaken]

Hi there,

for email addresses string such as "[EMAIL PROTECTED]; jack smith"

I might do wild card search like john* or jack* or [EMAIL PROTECTED] for 
*wherever.com
for phrase search i can do "jack smith"
for general search i might do "[EMAIL PROTECTED]"

I tokenized the string and indexed it into single Field using the Java File,
as mentioned in my earlier post and did searching.
Its working fine.

I want to know what can be the pitfalls of doing like this:
One i know is.. for each string, i should maintain two fields.. one to store
the original string and one that holds tokenized string.

What else ?

Thank You
miztaken
