regarding Query parser for relational operators

[Nellai]

Hi,

Is there any way to filter the search based on the modified date. For example, i need 
to fetch only those documents whose modified date > or < or between. Can any one help 
me to solve this.

Thanks a ton

AFAIK, nobody tried this yet. If you are familar with Lotus Notes
it should be esay to create your own indexer for Lucene and export
all required data from Lotus. Check out the sample code and documentation
how to write an indexer.
Using Verity Indexes causes to much work. I think it makes no sense, because
the index formats are different. So you have to write some kind of
converter.
It is much easier to create a new Lucene index using the original documents.

Re: '-' character not interpreted correctly in field names

[Terry Steichen]

I believe that the tokenizer treats a dash as a token separator.  Hence, the
only way, as I recall, to eliminate this behavior is to modify
QueryParser.jj so it doesn't do this.  However, doing this can cause some
other problems, like hyphenated words at a line break and the like.

(Of course, if you do make such a change, you'll have to go back and reindex
after such a change.)

I've run into this problem myself and I've 'punted' -  on certain fields,
when I index, I replace the dash with an underscore.  This isn't a real good
solution, and it does require me to keep remembering in which fields I have
to do this substitution in the search.  But, for the moment it works.  I'll
probably go back and make some kind of change later, when I have more time.

HTH,

Terry

Nellai,

Sounds like you want to use a range query.

[Terry Steichen]

Nellai,

That depends on how you've represented your date fields.  Please check
through the archives, 'cause there was quite a bit of discussion on this not
too long ago.

Regards,

Terry

It might be enough to just replace analyzer passed in to QueryParser
to do this? This is the case if QueryParser only handles modifiers outside
terms, and terms are passed to analyzer.
I think this is the case (QueryParser does  call the analyzer in couple of 
places, and one word may actually expand to a phrase or vice versa)?

Still, it seems like using a hyphen as separator shouldn't necessarily cause 
big problems when indexer does the same; queries against "2 - 5" would be 
phrase queries for "2 5", which is still reasonably specific (and should 
match the content).

On the other hand, simple analyzer and standard analyzer have pretty different 
tokenization rules, so it's important to make sure same analyzer is used for 
both indexing and searching (that mismatch can prevent matches easily).

Score-Limited Hits?

[Terry Steichen]

Is there an existing API that allows you to conduct a search such that only hits with 
a score greater than X are returned?

Terry

Not directly, but it's straightforward to compose from
Searcher.search(query, hitcollector)
and a hitcollector that implements
collect(docNr, score)
by comparing with your minimal score.

Have fun,
Ype

Is Java 1.4.1_01 supported?

[Justin Greene]

We are currently running lucene 1.2 on Sun Java 1.3.06_01.  We have moved a
number of our applications to 1.4.1_01.  Will lucene 1.2 work under 1.4.1_01
by just recompiling?

Thanks,
Justin
