I wrote this method, which returns me the analyzer:
static public Analyzer getAnalyzer()
{
PerFieldAnalyzerWrapper analyzer = new PerFieldAnalyzerWrapper(
new KeywordAnalyzer());
analyzer.addAnalyzer("placas", new UniqueTokensAnalyzer());
analyzer.addAnalyzer("ano", new UniqueTokensAnalyzer());
analyzer.addAnalyzer("no_reds", new NumberAnalyzer());
analyzer.addAnalyzer("nomes", new SimpleBrazilianAnalyzer());
analyzer.addAnalyzer("apelidos", new SimpleBrazilianAnalyzer());
analyzer.addAnalyzer("historico", new SimpleBrazilianAnalyzer
()); analyzer.addAnalyzer("modosAcaoCriminosa", new
SimpleBrazilianAnalyzer()); analyzer.addAnalyzer("nomeMunicipio", new
SimpleBrazilianAnalyzer()); analyzer.addAnalyzer("nomeBairro", new
SimpleBrazilianAnalyzer()); analyzer.addAnalyzer("logradouro", new
SimpleBrazilianAnalyzer()); analyzer.addAnalyzer("textoComplementar",
new SimpleBrazilianAnalyzer());
return analyzer;
}
SimpleBrazilianAnalyzer is my own analyzer that uses stopwords.
I pass that analyzer to MultiFieldQueryParser together with an array
with all the fields, ie. those fields and more.
When I do an AND search I'd like it to ignore stopwords. My best idea
so far is to make my own tokenizer and remove stopwords from the
search. How does that sound?
