public MultiFieldQueryParserWrapper(String[] fields, Analyzer analyzer, Map<String,Float> boosts)
It will, when parse(String query) is called, construct a query like this
(assuming the query consists of two terms and you specify the two fields
title
and body
):
(title:term1 body:term1) (title:term2 body:term2)
When setDefaultOperator(AND_OPERATOR) is set, the result will be:
+(title:term1 body:term1) +(title:term2 body:term2)
When you pass a boost (title=>5 body=>10) you can get
+(title:term1^5.0 body:term1^10.0) +(title:term2^5.0 body:term2^10.0)
In other words, all the query's terms must appear, but it doesn't matter in what fields they appear.

public static Query parse(String[] queries, String[] fields, Analyzer analyzer) throws ParseException
If x fields are specified, this effectively constructs:
<code> (field1:query1) (field2:query2) (field3:query3)...(fieldx:queryx) </code>
queries
- Queries strings to parsefields
- Fields to search onanalyzer
- Analyzer to useParseException
- if query parsing failsIllegalArgumentException
- if the length of the queries array differs from the length of the
fields arraypublic static Query parse(String query, String[] fields, BooleanClause.Occur[] flags, Analyzer analyzer) throws ParseException
Usage: <code> String[] fields = {"filename", "contents", "description"}; BooleanClause.Occur[] flags = {BooleanClause.Occur.SHOULD, BooleanClause.Occur.MUST, BooleanClause.Occur.MUST_NOT}; MultiFieldQueryParser.parse("query", fields, flags, analyzer); </code>
The code above would construct a query:
<code> (filename:query) +(contents:query) -(description:query) </code>

- Query string to parsefields
- Fields to search onflags
