document boost and omitted norms

Is it so that document and field boosts are omitted together with Field#setOmitNorms? By setting lengthNorm to 1f in the Similarity for these fields and not omitting norms would fix it? karl - To unsubscribe, e-mail: [EMA

Question About Hits

This is more of a trying to understand the design sort of question, but its still something I need to able to succinctly express to my project manager. I know that lucene is by design not allowing us to see which fields were hit for a given document in an easy manner. Instead it presents us w

Re: Ability to sort integer fields on large index

You should use DateTools to break up your time stamp into multiple fields. This can work a lot faster than using a field with so many different terms. Are you using a RangeQuery? If you are, ditch it and use a ConstantScoreRangeQuery. The former will expand the query to a boolean that contains eac

Ability to sort integer fields on large index

Here is the problem: - Single Large index with upto 200 million documents - Each document contains field using epoch timestamp format (padding is required when creating range requests) - One of the frequently used search query, a range request on the timestamp field (10 digits) - Other searc

I believe you must capitalize the AND. lower-case 'and' is ignored. you could also construct your own BoolenQuery if you wanted. I recommend copy of Luke to interactively examine how queries are parsed. Also, toString is your friend Best Erick On Fri, Apr 4, 2008 at 9:41 AM, Jamie <[EMAI

Hi there I need some help in understanding Lucene's query mechanism. I am receiving unexpected query results when combining terms with AND and OR operators. We are using Lucene to index emails. Our problem is that when we execute a search such as '(from:"[EMAIL PROTECTED]") and (to:"[EMAIL PR

I am using ngrams and I need to force that a group of them are together, but if any of them fails, I need that the document is also scored.

Re: PhraseQuery little bug?

In Lucene sytax in htis case ~5 means slop=5 - this is for Span queries. I think the problem is that in the class PhraseQuery the slop that we set some times is interpreted as inclusive other times exclusive. When it is considered inclusive then the distance between "apple" and "pear" is 5, bec
