createWeight

public SpanWeight createWeight(IndexSearcher searcher,
                               boolean needsScores)
                        throws IOException

Description copied from class: SpanQuery

Create a SpanWeight for this query

Specified by:

createWeight in class SpanQuery

Parameters:

searcher - the IndexSearcher to be searched across

needsScores - if the query needs scores

Returns:

a SpanWeight

Throws:

IOException - on error

setBoost

public void setBoost(float b)

Description copied from class: Query

Sets the boost for this query clause to b. Documents matching this clause will (in addition to the normal weightings) have their score multiplied by b.

Overrides:

setBoost in class Query

getBoost

public float getBoost()

Description copied from class: Query

Gets the boost for this clause. Documents matching this clause will (in addition to the normal weightings) have their score multiplied by b. The boost is 1.0 by default.

Overrides:

getBoost in class Query

rewrite

              throws IOException

Description copied from class: Query

Expert: called to re-write queries into primitive queries. For example, a PrefixQuery will be rewritten into a BooleanQuery that consists of TermQuerys.

Overrides:

rewrite in class Query

Throws:

IOException

clone

public Query clone()

Description copied from class: Query

Returns a clone of this query.

Overrides:

clone in class Query
