I have a bunch of html text boxes on a page to represent database fields and
then programmatically add the field name and a colon in front of each value
before sending it on to the QueryParser--like--> description:harley
keyword:jacket

When I need to search for the same thing across multiple fields I added a
field to the document when I indexed that had the values from ALL of the
fields, a bit redundant but I can't find a better way. I have 8 fields
indexed of 1.2 million documents for a grand total of 600MB and I still get
good search times.

Hi Charles,
Currently Lucene does not give you a query which will search all fields.
The easiest way to do this is to great a queryString will all the fields
based on the enteredSearchString.

So if someone enters "foobar" then convert this into
category:foobar OR body:foobar
where the format is [fieldname]:[query string]
Of course you can use AND or OR depending on what you want to accomplish.

Hope that helps.

Good idea, I had not though to delimit any of the params. I can operate in
that fashion, but it present a few problems:
All fields would have to be concatenated.
Date (Search by date < or >) would have to be pulled out to java
All IS queries would have to be pulled by java.

This means that I would have to get the entire result set back based only
on the actual word query, and then sort through the documents turning those
params into date object, etc - performing an entire extra set of search and
elimination operations... doubtlessly slowing the whole efficient process
down to a crawl.

However, if it is the only way...

I looked at the MultiSearcher, but that only seemed to possess the ability
to search multiple indexes, not fields. I also look at the multi-term
query, but the constructor for that only takes one term, not an array of
terms, and I don't see that a term can be constructed that contains
multiple terms !? I'm a bit lost as to why it should be called multi
anything in the first place.

So if I have three fields in my Document, labeled on insert into the
document as:
headline
category
pub_date


and I need all headlines that contain 'Bush'
from all stories with a category of 'National'
that were published on 2002/01/05:

Would I:

1. Have to have inserted upon concatenation all of this data into a single
field?
pub_date:2002/01/05 category:National headline:A whole lot of people really
love Bush

The query would be put together so?
pub_date:2002/01/05 AND category:National AND Bush
This doesn't seem like it would work specifically for the headline field,
though it would work just fine for the others... maybe a solution here
would be to tag entire fields before concatenation into the searchable
field and use regular expressions so we could query for
/<headline>.*Bush.*<\/headline>/i. Seems a bit complicated, though.

Or, does Lucene actually understand that the field:content is a field pointer?

The only other way that I can think would be usable (especially for date >
some_time) is to search only for the keyword query ('Bush' in this case),
enumerate through all of the Documents returned, add them to my own
collection, and then begin to weed them out condition by condition.

This is great Kelvin,
Sorry I didn't see it before.
I'll add it to the list of contributions.

Peter,

As advised, re-released under APL. :) There were some changes to QueryParser
constructors in rc3, and these are reflected here as well.

FWIW, I've also attached a javascript lib and accompanying HTML which
constructs a Lucene multi-field query using a HTML form.

Regards,
Kelvin

Odd, I'm positive I uploaded the HTML file with the other attachments. I've
