Method Detail

parse

public static org.apache.lucene.search.Query parse(java.lang.String query,
                                                   java.lang.String[] fields,
                                                   org.apache.lucene.analysis.Analyzer analyzer)
                                            throws org.apache.lucene.queryParser.ParseException

Parses a query which searches on the fields specified.

If x fields are specified, this effectively constructs:

 
 (field1:query) (field2:query) (field3:query)...(fieldx:query)

parse

public static org.apache.lucene.search.Query parse(java.lang.String query,
                                                   java.lang.String[] fields,
                                                   int[] flags,
                                                   org.apache.lucene.analysis.Analyzer analyzer)
                                            throws org.apache.lucene.queryParser.ParseException

Parses a query, searching on the fields specified. Use this if you need to specify certain fields as required, and others as prohibited.

 Usage:
 
 String[] fields = {"filename", "contents", "description"};
 int[] flags = {MultiFieldQueryParser.NORMAL FIELD,
                MultiFieldQueryParser.REQUIRED FIELD,
                MultiFieldQueryParser.PROHIBITED FIELD,};
 parse(query, fields, flags, analyzer);
 
 

The code above would construct a query:

 
 (filename:query) +(contents:query) -(description:query)
