Ok. I'm using positions at ANALYZED fields where search is by terms. The others
fields, "NOT_ANALYZED", the search is by complete term, as culture code, url,
document code.
The index has documents in three languages (Spanish, English and Portuguese
(BR)). When perform a search, I realize filters using TermoQuery with fields
"NOT_ANALYZED" and use PhraseQuery or PrefixQuery TermoQuery and added in a
BoolenQuery with fields analyzed. The same code works with StandardAnalyzer. By
using BrazilianAnalyzer most terms do not return a result of the stored
documents with this analyzer.
In the code attached to "searchExpresion" is the phrase containing the words
entered to search by the end user. I do search containing all the words, or any
of the words or the whole phrase. This method makes my object "BooleanQuery"
only for the content (full text).
Below is a sample of the settings of my columns to index. Some values ??are
listed here with the names of the columns.
Below this code snippet, a snippet of the implementation of the search.

It's working perfectly just to other analyzers. With BrazilianAnalyzer I search
the term "ferramenta" and returns nothing. There are documents in "es-ES" and
"en" in the index with this term. If I search by filtering the field
"DocumentCulture" with value "es-es" (field of culture not_analyzed and text
field [SnowBallAnalyzer ("Spanish")]) has documents. If I filter by "pt-BR"
(field of culture not_analyzed and text field [BrazilianAnalyzer]) comes
nothing.
Is it a bug in [BrazilianAnalyzer]?

Assunto: Re: BrazilianAnalyzer don't woks with any BooleanQuery
can you tell us more about your index side of things? Are you using positions
in the index since I see PhraseQuery in your code?
Where are you passing the text you are searching for to the BrasilianAnalyzer,
I don't see it in your code. You need to process you text at search time too to
get results.
