Have you looked at SpanNearQuery? From what you describe, it looks to be
what you want. The constructor takes slop as well as a boolean whether order
is relevant. The array of SpanQuerys would probably consist of a bunch of
SpanTermQuerys.

Hello,
I'm trying to understand Lucene's slop value a little better, as
what I'm able to Google about it seems a little ambiguous.
My main goal is to search for a linear sequence of keywords in a
specific order over a given range. For instant I'd like a query of
"fate ships" to find

It is just a property of gmail, take a look at thee archives after a

I was reading a book on SQL query tuning. The gist of it was that the
way to get the best performance (fastest execution) out of a SQL select
statement was to "create" execution plans where the most selective term
in the "where" clause is used first, the next most selective term is
used next, etc.
Hi Mike,
Thanks for the information!

Wow. Looking at the implementation of
http://lucene.apache.org/java/docs/api/org/apache/lucene/index/IndexReader.h
tml#open(org.apache.lucene.store.Directory) I've now realised that when you
create an IndexReader (clue it is abstract), you actually instantiate a
MultiReader, with an IndexReader for
This is how we solve the range query problem using filters. The nice
part about it is you can use a range in a query so several ranges can be
ORed/ANDed or NOTed together if required, instead of applying a range
filter to the who query. (Assumes dates in MMDD format)
Hope this helps Mike.

Sorry for the delayed response. It takes me a while to get my head around
Lucene.
I've got parallel indexes, which means that chorological ordering by doc ID
would need to be a bit more sophisticated. It strikes me that there must be
some performance advantage doing it though.
I'll see if I can
What? You actually want me to put forth some effort? That's crazy talk ..
Thanks, I think I've got it now.

ARRRGH!!! That's it. Darn, I was half asleep last night when I was
experimenting. I totally feel like a dope.
It worksThanks!

Yes.
Although technically you could pass the content unparsed it will contain a lot
of unintelligible garbage in the form of markup and images.
All Lucene classes deliberately try and avoid the mucky
Hi,
I'm using MoreLikeThis class to find similar documents... but I'm not
sure if it is correct to pass as argument a Pdf file to

Trying to be more clear:

and add fields to index)
2) Now I want
