Re : porting lucene on to mobile phone

Hai,

      Has any one tried to port lucene on to a mobile phone.
I need a
text-based search engine for mobile phone as part of my
project.

      Or is there any other J2ME based API which can be used
to search the
text in mobile phones.

thanks,
Saikrishna.

There was some discussion about this here on the forums some
year(s?)  
ago. The major problem back then was the lack of floaing
points.  
Also, as Lucene moves towards Java 1.5 the possible
compabillity with  
J2ME moves further away.

Before asking too much you should tell us some about your
project.  
How large is the corpus, what features do you require, et c?
I.e. do  
you really need Lucene, is it perhaps sufficient with
something  
simple as a trie-pattern?

Hai,

     Thank you for responding.

 I have abt 17,00,000 documents in 1000 files. I need to
index the titles of
those documents with out storing the titles and storing the
file name.

When ever I issue a query I need to get the name of the file
in which that
document exists.

thanks,
Saikrishna.

Not sure I understand what you say here.

You want to create 1,7 million documents containing a short
and  
indexed field: title, and a stored field: file name?

You only require boolean term queries? And no scoring,
sorting or  
anything like that?

In that case, it should not be that hard to rewrite Lucene
for your  
needs.

See LUCENE-584 for seperation of Matcher and Scorer.

Yes this is what I need.

I need the name of the file in which the best matched title
exists. Don't I
need scoring here.

Suppose my query is "q1 q2 q3" and their are
titles like "q1
q2","q3","q1",etc.  Among this the
best mateched title is "q1 q2", and I
need the name of the file in which the document with title
"q1 q2" occur.

I don't know how you would decide what the best matched
document is  
without scoring the results?

Yes we need scoring to decide what is best matched.

Can I use ucene with some changs, for the purpose of
matching and with OUT
SCORING the query given.

thnks,
Saikrishna.

Sorry, but I don't understand your question?

In order to run Lucene on J2ME you need CLDC1.1 or later,  
alternatively modify Lucene to use some sort of floating
point library.

Sorry I couldn't frame my question correctly due to typos.

this is what you said earlier

"""

sorting or
anything like that?

for your
needs.

"""

Can I rewrite lucene to match the given query with some
title ?

Sorry, I still don't understand.

If you only want matching and no scoring (i.e. you will not
get to  
know what document was the better or worse match), then it
is no that  
hard to get rid of all floating points.

See LUCENE-584 for seperation of Matcher and Scorer.
