Class SpanTermQuery
- Cloneable, Serializable
public class SpanTermQuery
Matches spans containing a term.
boolean | equals(Object o) - Returns true iff
o is equal to this.
|
void | extractTerms(Set terms) - Expert: adds all terms occuring in this query to the terms set.
|
String | getField() - Returns the name of the field matched by this query.

|
Term | getTerm() - Return the term whose spans are matched.
|
Collection | getTerms() - use extractTerms instead

SpanTermQuery
public SpanTermQuery(Term term)
Construct a SpanTermQuery matching the named term's spans.
equals
public boolean equals(Object o)
Returns true iff o
is equal to this.
extractTerms
public void extractTerms(Set terms)
Expert: adds all terms occuring in this query to the terms set. Only
works if this query is in its
rewritten
form.
- extractTerms in interface Query
getField
public String getField()
Returns the name of the field matched by this query.
- getField in interface SpanQuery
getSpans
public Spans getSpans(IndexReader reader)
throws IOException
Expert: Returns the matches for this query in an index. Used internally
to search for spans.
- getSpans in interface SpanQuery
getTerm
public Term getTerm()
Return the term whose spans are matched.
getTerms
public Collection getTerms()
use extractTerms instead
Returns a collection of all terms matched by this query.
- getTerms in interface SpanQuery
hashCode
public int hashCode()
Returns a hash code value for this object.
toString
public String toString(String field)
Prints a query to a string, with
field
assumed to be the
default field and omitted.
The representation used is one that is supposed to be readable
by
QueryParser
. However,
there are the following limitations:
- If the query was created by the parser, the printed
representation may not be exactly what was parsed. For example,
characters that need to be escaped will be represented without
the required backslash.
- Some of the more complicated queries (e.g. span queries)
don't have a representation that can be parsed by QueryParser.
