Searching all the fields
If I want to search a word in all my fields, can I do it passing the String field like a null to a QueryParser ? If I can´t do it this way, what must I do ?

You're most welcome.

Are you looking to search on all the fields? If so, I guess this is an OK
approach, but I believe your results may be distorted unless all Hits are
sorted by score before adding to the HashSet.

First thank to Kelvin Tan and the rest of the people for his support and help.
Well, I talked to my boss and I suggested the posibility of create a new field with all the content. This thing duplicate the Index but the search was still very very quick. But the man didn´t accept this way so... now I make one search for each of my fields and, at the same time, I filt the hits with a HashSet. What do you think about this ?

Yep, I posted the code on Tuesday. It's somewhat more flexible than the
method suggested in the FAQ.
It's not in the mail-archives yet, so if you want it just drop me an email.

Kelvin

You can't do it that way. One way is to gather all the fields
you want to search across into one big field called "contents"
or something. That is in the FAQ at
http://www.lucene.com/cgi-bin/faq/faqmanager.cgi?file=chapter.search&toc=faq#q12
and is the way I do it.
A few days ago someone posted some code that, I think, took a term
and prefixed it with assorted different field names. If my
recollection is correct that might be another way.
