HitCollector with RemoteSearchable

Hello, Can I use HitCollector with RemoteSearchable ? I am tring to use it. But I got the following error. java.rmi.MarshalException: error marshalling arguments; nested exception is: java.io.NotSerializableException: org.apache.lucene.search.MultiSearcher$1 at sun.rmi.server.U

Re: Blackberry

Can you provide some stats on the Zarus implementation you´re using, I´m curious about indexing and searching speeds, also memory and index space consumption, J2ME functions on a whole different level then J2SE or J2EE for that matter. Nader Henein -- Original Message ---

term scoring (idf) question

I'm trying to figure out why idf is multiplied twice into the score of a term query. It sort of makes sense if you have just one term... the original weight is idf*boost, and the normalization factor is 1/(idf*boost), so you multiply in the idf again if you want the final score to contain an idf

Re: Question: force a field must be matched?

Yes, "+" is what I missed! Thanks. Suppose there is a book published by 3 publishers (I don't know how that works in real world): // At index time: doc.add( Field.Keyword("publisher", "Manning") ); doc.add( Field.Keyword("publisher", "SAMS") ); doc.add( Field.Keyword("publisher", "O'Reilly"

: I wonder if that's the same as : : queryString + " publisher:Manning" : : and pass on to the query parser? assuming queryString is a java variable containing your initial query, then you are close, but not quite. If you want to tell QueryParser to make a clause "required" then you have to pre

Re: Question: dynamic sorting

Hi Otis, Thanks for your answer. I do have LIA (but not with me now physically), and have the impression that the search ordering is predetermined (at index time); what I want is search-time ordering, e.g., "I'm at (x,y) now and low on gas; find me the closest airports that can land 747, the clos

Re: Question: dynamic sorting

Hi James, Check out the org.apache.lucene.search.package, there are several sort classes that will let you write a custom sorter. If you have a copy of LIA, look at chapter 6 for an example ( http://www.lucenebook.com/search?query=custom+sort+section%3A6* ) Otis --- James Huang <[EMAIL PROTECT

Re: Small problem in searching

Hi, I think Lucene transforms the prefix match query into all sub queries where the searching for a prefix could result into search for all terms that begin with that prefix. For "postfix" match, I think you need to do more work than relying on Lucene's query parser. You can iterate over the

Question: dynamic sorting

Suppose I have a book index with field="publisher", field="title", etc. If a user has bought Manning books, then I like to sort the result with Manning books listed first. In essence, I'm asking for a parameterized custom sorting. Is there a way to do this? Thanks, -James -

Small problem in searching

Hi guys, I have some problem while searching using Lucene. Say I have some thing like "tirupathireddy" or "venkatreddy" in the index. When i search for string "reddy" I have to get those things (i.e. "tirupathireddy" and "venkatreddy"). I have read in Query syntax of Lucene that * wil

Re: Terms given a filter?

This sounds like another "group by" totalling question. See the generic "group by" totalling code I posted here: http://marc.theaimsgroup.com/?l=lucene-dev&m=111044178212335&w=2 In your example there is no quality threshold (just a filter bitset of "books in 2002") so you can replace the "scores"

RE: Is Lucene for Me?

It is something you have to do yourself and it depends on the requirements. One of our db-searcheengines scans the database for updates periodically (all records have a 'last-modified' field). Another of our solutions doesn`t scan the db, but is activated by a server application to update the in
