??????Why does QueryBuilder.createBooleanQuery create something differentfrom input?

[308181687]

Because of stupid bug in your app. I have tested your code, it work fine:


title:?? title:?? title: title:6500 title:?? title: title: 
title: title:?? title:?? title: title:??




--  --
??: "Cheng";;
: 2014??5??10??(??) 10:16
??: "java-user"; 

: Why does QueryBuilder.createBooleanQuery create something differentfrom 
input?



Hi,

I build a query using
QueryBuilder.createBooleanQuery("title","6500??").

When I check the query, the toString() of this query looks like:

Query: title:?? title: title: title:2. title: title: title:
title: title: title: title: title: title: title:?? 
title:??
title:3. title: title:?? title:?? title:?? title:?? title: title:?? 
title:
title: title:?? title:?? title: title: title: title: 
title:
title:?? title:?? title: title:?? title: title: title:logo 
title:
title: title:4.iphone title:2g title:?? title:3g title: title: 
title:??
title:?? title:0.9.3

This is totally different from the input 
"6500??".

Can someone tell me why?

Thanks

Re: Lucene: Index Writer to write in multiple file instead make one heavy file

[Michael McCandless]

You can tell the MergePolicy to limit the maximum size of segments it
should merge.

Also, you should try to upgrade: 3.0.1 is REALLY old.

I was trying to solve pretty much the same thing few weeks back and I ended
up using the NGram tokenizer. Although it made my index much larger (the
index grew 15x), the fulltext queries are pretty fast and I don't have to
use wildcards in queries.

Unfortunately not always. Looks like j.i.File is getting param child == 
null
What might go wrong in openIfChanged?
Thanks for any advices/hints

Re: How to locate a Phrase inside text (like a Browser text searcher)

[Michael Sokolov]

ShingleFilter can help with this; it concatenates neighboring tokens.  
So a search for "good morning john" becomes a search for


"goodmorning john" OR
"good morningjohn" OR
"good morning john"

it makes your index much bigger because of all the terms, but you may 
find it's worth the cost

You might be able to handle "Mailhow" using the 
DictionaryCompoundWordTokenFilter, but that requires that you create a 
complete dictionary of terms that can split off. That's not very 
practical. In truth, Lucene/Solr doesn't have a good out of the box 
solution for this use case.

Re: writer.updateDocument() not working (possible bug?)

[Jamie]

Mike

Thanks for the tip. The doc was being loaded using the method 
searcher.doc(scoreDoc.doc,getLoadFields()). Obviously, only a minority 
of fields were being loaded. However, when using the method 
searcher.doc(scoreDoc.doc), the doc appears to update when 
updateDocument(term,doc) is called. Can you confirm whether the full 
document will be returned when I call searcher.doc(scoreDoc.doc)? if 
not, what is the recommended way to get the original document from the 
index (if possible)? Perhaps, reader.document(i)?


Thanks in advance

Jamie

How did you produce the document that you are sending to
updateDocument?  Are you loading it from IndexReader.document() or
IndexSearcher.doc(), changing it, then passing that to
IW.updateDocument?  If so, that's probably your bug: a loaded document
is not identical to the original Document you indexed.  In 5.0 we've
fixed this to be strongly typed ...

Greetings

I am using Lucene NRT search. After calling writer.updateDocument(term, doc)
and then search(), the document is no longer visible in the search results.
The program must be restarted to see it again. In addition, the update is
not being applied. The original document (before the update) is visible in
the search results. If updateDocument(term,doc) is called, passing the
original doc (without any changes), the doc is still removed from the index
(i.e. the change is not the cause). On each search I am calling indexReader
= DirectoryReader.open(writer, true); We have tried to call commit() and/or
close() immediately after the update, but it makes no difference.

This occurs both in Lucene 4.7.2 and 4.8. As far as we know, our code used
to work with prior versions of Lucene. Has anyone encountered this?

Regards

Jamie

Normally Lucene does not produce a single large file. I guess you are 
performing an optimize. Don't do that (it is not really recommended anyway) and 
you should have multiple smaller files.

If that was not clear, then please show us the part of your code that handles 
index updates.
