Examples of org.apache.nutch.searcher.QueryFilters

org.apache.nutch.searcher.QueryFilters
Creates and caches {@link QueryFilter} implementing plugins. QueryFilterimplementations should define either the "fields" or "raw-fields" attributes for any fields that they process, otherwise these will be ignored by the query parser. Raw fields are parsed as a single Query.Term, including internal punctuation, while non-raw fields are parsed containing punctuation are parsed as multi-token Query.Phrase's.

    throws IOException {
    NutchAnalysis parser = new NutchAnalysis(
          queryString, (analyzer != null) ? analyzer : new NutchDocumentAnalyzer(conf));
    parser.queryString = queryString;
    parser.queryFilters = new QueryFilters(conf);
    return parser.parse(conf);
