Not quite sure what you ask for, but I think you want to use a span
near query (for adding boost to phrases) in a disjunction max query
(to define weights of the different fields).

I have a question about the reopen functionality in Lucene 2.9. As I
understand it, since FieldCaches are now per-segment, it can avoid reloading
everything when the index is reopened, and instead just load the new
segments.
For background, like many people we have a distributed architecture wher
Hello,
I have created a custom Tokenizer and am trying to set and extract my own

tags don't correspond to these values but seem to co
Hi Mike,
The first thing that comes to mind is to run a query for each document
type (assuming that you have a field that stores the type) and qualify
the document type: for example type:pdf. Then you would have to write
something to combine the query results drawing an equal number of hits
Hi Mike,
I'd simply store a field "doctype" with values "pdf", "txt", "html"
and perform a separate search for each type. Although, I'd be
interested if anyone has a cooler way of doing this.
Cheers,
Phil

I was wondering if there is any way to control what kind of documents
are returned from a search. For example, lets say we have an index
built from different types of documents (pdf, txt, html, etc.). Is
there a way to have the first x results have a specified distribution

Hi,
In an attempt to balance searching efficiency against the number of open file
descriptors on my system, I cache IndexSearchers with a "last used" timestamp.
A background cache manager thread then periodically checks the cache for any
that haven't been used in a while and removes them from
Hi Anshum,
That is exactly the same code he is using (only that he does not instantiate
the collector; IndexSearcher.search(query, int) does exactly that
internally :-)
His problem was, that if offset+limit is large or Integer.MAX_VALUE that he
runs out of memory.

@Christian : Which version of Lucene are you using?
For lucene 2.9 this would work.
*__code snippet__*
IndexReader r = IndexReader.open("/home/anshum/index/indexname", true);
IndexSearcher s = new IndexSearcher(r);
QueryParser qp = new QueryParser("testfield",new StopAnalyzer());
Query q = qp.par
I forgot to mention: Because of this, e.g. even Google (who do not use
Lucene :-]) does not let you go beyond a limit to a very large page number.

Hi, thanks for the answer but it didn't work.
I stopped rewriting the query and used the queryscorer but it don't
highlight.
The part of the query i'm doing wildcard is the number part, like this:
"HC 100930027253"
The HC is hightlighted but the numbers aren't:
"Habeas Corpus HC 100930027253 ES 10
Thanks, Mike.
The reason is I wanna dig deeply.
I just read the code. And found that the index namespace (IndexWriter!) in
so tough for me.
Is there any document, resource or blog about the code?

On Thu,
It's better to use the TermEnum API (IndexReader.terms()) to step

Can you turn on IndexWriter's infoStream and post the resulting output?
Enabling calibrateSizeByDeletes doesn't automatically mean that
segments with many deletes will be merged. EG if your mergeFactor is
high relative to the number of segments you have at each level, then
no merging will take pl
You could get the hits in a collector and pass the sort to the collector as
it would be the collect function that handles the sorting.

Hallo Chris,
You are using TopDocs incorrectly. Normally you use *not* Integer.MAX_VALUE,
as the upper bound of your pagination window as numer of documents. So if
user wants to display documents 90 to 100, just set the number to 100 docs.
If the user then goes to docs 100 to 110, just reexecute t

Per segment over many segments is actually a bit faster for none sort
cases and many sort cases -but an optimized index will still be
fastest - the speed benifit of many segments comes when reopening - so
