- public final class Term
- extends Object
A Term represents a word from text. This is the unit of search. It is
composed of two elements, the text of the word, as a string, and the name of
the field that the text occured in, an interned string.
Note that terms may represent more than words from text fields, but also
things like dates, email addresses, urls, etc.

Term
public Term(String fld,
String txt)
- Constructs a Term with the given field and text.
field
public final String field()
- Returns the field of this term, an interned string. The field indicates
the part of a document which this term came from.
text
public final String text()
- Returns the text of this term. In the case of words, this is simply the
text of the word. In the case of dates and other types, this is an
encoding of the object as a string.
equals
public final boolean equals(Object o)
- Compares two terms, returning true iff they have the same
field and text.
- Overrides:
equals
in class Object
hashCode
public final int hashCode()
- Combines the hashCode() of the field and the text.
- Overrides:
hashCode
in class Object
compareTo
public final int compareTo(Term other)
- Compares two terms, returning an integer which is less than zero iff this
term belongs after the argument, equal zero iff this term is equal to the
argument, and greater than zero iff this term belongs after the argument.
The ordering of terms is first by field, then by text.
